Q & A

  • Что такое искусственный интеллект?

    -Искусственный интеллект - это раздел компьютерных наук, который занимается созданием программ или машин, способных выполнять задачи, требующие человеческого интеллекта, такие как обучение, понимание языка и решение проблем.

  • Какие существуют подходы к созданию искусственного интеллекта?

    -Существуют два основных подхода: bottom-up (снизу вверх), который изучает внутреннюю структуру объекта с интеллектом (например, человека) для имитации интеллектуального поведения, и top-down (сверху вниз), который сосредотачивается на изучении самого интеллектуального поведения и разработке систем, способных его воспроизводить.

  • Чем отличается сильный искусственный интеллект от слабого?

    -Слабый искусственный интеллект способен выполнять конкретные задачи в рамках определенной области, в то время как сильный ИИ обладает общим интеллектом, сравнимым с человеческим, и может решать задачи в различных областях.

  • Какова основная идея теста Тьюринга?

    -Основная идея теста Тьюринга заключается в том, что если машина способна убедить человека в том, что она не отличается от другого человека, отвечая на вопросы через текстовый чат, то машина может считаться обладающей интеллектом.

  • Почему поведение не всегда является показателем интеллекта?

    -Поведение может быть сложным и разнообразным даже у существ без развитого интеллекта, как, например, у крокодилов. Наличие сложного поведения не обязательно указывает на способность к планированию или размышлению, которые являются ключевыми аспектами интеллекта.

  • Что такое обучение в контексте искусственного интеллекта?

    -Обучение в контексте искусственного интеллекта - это процесс, в ходе которого машина или программа улучшает свои способности к решению задач или адаптации к новым условиям на основе предыдущего опыта или данных.

  • Какие методы используются для оценки детского интеллекта?

    -Для оценки детского интеллекта используются различные задачи, например, тесты на сообразительность, в которых детям предлагается дополнить последовательность слов или изображений, либо решить логические головоломки.

  • Что такое глубокое обучение?

    -Глубокое обучение - это подмножество методов машинного обучения, использующее многослойные нейронные сети для анализа больших объемов данных, что позволяет системам обучаться, распознавать образы и делать выводы на уровне, сравнимом с человеческим.

  • Почему искусственный интеллект считается менее развитым, чем интеллект мыши?

    -На момент речи искусственный интеллект считается менее развитым, чем интеллект мыши, потому что ИИ еще не способен к такому же уровню принятия решений, обучения и адаптации к изменяющимся условиям, как живые существа с развитым мозгом.

  • Как изменится общество с развитием искусственного интеллекта?

    -С развитием искусственного интеллекта многие задачи, традиционно выполняемые людьми, будут автоматизированы, что может привести к изменениям в структуре трудового рынка, требованиях к образованию и социальной организации общества.

🧠 Введение в искусственный интеллект

Александр рассказывает об основах искусственного интеллекта (ИИ), различая подходы к его созданию: снизу вверх, изучая внутреннее устройство интеллекта, и сверху вниз, фокусируясь на внешнем поведении. Обсуждается разделение ИИ на слабый и сильный, а также введение в тест Тьюринга как метода определения наличия интеллекта у машин.

05:01

🧩 Понимание интеллекта и обучения

Обсуждается различие между поведением и интеллектом, подчеркивается, что наличие сложного поведения не обязательно указывает на интеллект. Александр разъясняет, что истинная суть интеллекта заключается не в вычислениях в ответ на вопросы, а в способности к обучению и запоминанию информации для будущего использования.

10:04

🔬 Структура мозга и нейрокортекс

Разбирается структура мозга, включая нейрокортекс, который отвечает за высшие когнитивные функции. Александр объясняет, как работают нейроны и нейронные сети в мозгу, создавая иерархические связи для обработки и анализа информации.

15:04

📚 Обработка информации и глубокое обучение

Обсуждается, как человек обрабатывает информацию, начиная с восприятия простых форм и заканчивая сложными абстракциями. Александр вводит концепцию глубокого обучения в нейронных сетях, сходство их структуры с нейрокортексом человека и их способность к обучению на примере контента из интернета.

20:06

💡 Искусственный интеллект и общество

Александр рассматривает социальные и экономические последствия развития искусственного интеллекта, включая потенциальное превосходство ИИ над человеческим интеллектом и вызовы, связанные с автоматизацией труда. Предлагаются способы адаптации общества к новым реалиям, в которых ИИ играет ключевую роль.

Highlights

Two different approaches to creating artificial intelligence: bottom-up and top-down.

In 2015, creating programs that act as if they were intellectual is called programming.

Artificial intelligence can be divided into strong and weak.

Alan Turing's test for machine intelligence involves a machine persuading us it is human.

Turing's test involves a quizmaster, two players, and a machine, with the goal of indistinguishing the machine from a human.

Intelligence is often associated with human abilities such as analyzing the world, learning, and rational behavior.

Behavior alone may not be an index of intelligence, as demonstrated by the complex behaviors of crocodiles versus humans.

The human brain's cerebral cortex is responsible for high-level memory and intellectual functions.

The neocortex is a crucial part of the human brain, involved in complex behaviors and decision-making.

Intelligence is the ability to predict the future and create programs or algorithms based on those predictions.

Deep learning, a significant advancement in neural networks, is inspired by the structure of the human neocortex.

Artificial intelligence has surpassed human accuracy in picture recognition tasks, including identifying cats in images.

The evolution of AI is expected to surpass human intelligence at an exponential rate once it reaches a certain threshold.

The development of AI may lead to machines outperforming humans in most tasks, necessitating a reevaluation of human labor and purpose.

The speaker suggests that AI could potentially be the last invention of humanity, as it may evolve beyond our control.

The future of AI development requires careful consideration to ensure it aligns with human goals and survival.

The speaker proposes that work may need to become independent of salary, with people working because they enjoy it, not for financial necessity.

AI development must focus on creating AI that will not destroy humanity, which is an even more challenging task than creating AI itself.

play00:06

Hello,

play00:07

I’m Alexander and I read

play00:09

popular-science lectures. And now I’m going to tell you something

play00:11

about artificial intelligence.

play00:12

We’ll talk little about

play00:14

computers,

play00:15

much about intellect and a bit about

play00:16

artificial intelligence -

play00:18

what it is, how to create it and so on.

play00:20

play00:21

There are two essentially different approaches to

play00:24

the creation of artificial intelligence:

play00:26

a bottom-up

play00:28

approach,

play00:28

when we

play00:29

study something with

play00:31

an intellect, for example,

play00:33

us,

play00:34

and try to represent

play00:36

the inner stucture with a view

play00:38

to get some kind of intellectual behaviour.

play00:41

A top-down approach is

play00:42

when we study

play00:44

the intellectual behaviour itself,

play00:46

for example an ability to

play00:47

distinguish a text by hearing it or to distinguish

play00:50

a text from images

play00:52

and then design some

play00:54

computer systems that

play00:56

implement this intellectual

play00:57

function.

play01:00

In 2015, creation of programs that act as

play01:02

if they were intellectual

play01:04

is called just programming.

play01:06

Nobody needs silly programs

play01:08

so we’ll talk about

play01:09

bottom-up coding, about

play01:11

creation of programs that are

play01:13

or may some day be intellectual.

play01:18

Except dividing into bottom-up and

play01:20

top-down, we can also divide artificial intelligence into

play01:22

strong and weak ones.

play01:23

All the things you see

play01:25

can discern the object,

play01:27

pursue an aim and wash your sweater gently,

play01:30

they all exist,

play01:31

but none of them has

play01:33

AI.

play01:34

On the other hand,

play01:36

all these guys

play01:39

(laughing)

play01:41

all these guys

play01:42

have AI, in my opinion,

play01:44

but still do not

play01:46

exist. We will talk mostly about them.

play01:52

How to distinguish intelligence or consciousness

play01:54

in a robot or a computer

play01:55

program?

play01:56

Alan Turing, one of the computer science pioneers,

play01:59

offered an elegant answer:

play02:01

let the machine persuade us itself.

play02:03

His method of verification is, basically, as follows:

play02:05

there is a quizmaster and two players,

play02:07

one of which is a machine.

play02:09

The quizmaster does not know who is who.

play02:11

The quizmaster asks players some questions

play02:13

using a chat, the players answer them.

play02:16

The quizmaster’s task is to define which of players

play02:18

is a machine.

play02:20

The machine’s task

play02:22

is to confuse the quizmaster in order

play02:24

he couldn`t define who is a machine

play02:26

and who is a person.

play02:27

The game is not cut down to

play02:29

the ordinary phrases, such as “what’s your name?”

play02:31

One can ask, for instance: “Could you please compose a poem about poetry

play02:34

and autumn?”

play02:35

And a normal adequate

play02:37

computer’s answer would be “For goodness sake, I can’t write a poem!”

play02:41

Or, you can ask a computer:

play02:44

What, in your opinion, equals 314 plus 567?

play02:48

And a computer, having self-respect,

play02:50

should think for three seconds at least

play02:52

before he answers 881.

play02:55

But by highest standards he should make a mistake.

play02:57

That is, this game is more difficult

play02:59

than just correctly answering questions -

play03:00

you need to answer as a person.

play03:02

If you ask which question I would ask as quizmaster in a Turing test

play03:08

I would answer:

play03:09

"Which question would you ask

play03:11

as a quizmaster in a Turing test?”

play03:16

Turing’s idea is as follows:

play03:18

if a machine can convince us

play03:21

that

play03:22

we can’t distinguish between a machine and a person,

play03:25

then it is probably intelligent,

play03:27

has consciousness or at least

play03:28

is more intelligent then people, then how can people define

play03:30

what is intelligent?

play03:32

On the other hand, Turing’s test

play03:34

is just an imitation game.

play03:37

That is, does a computer which

play03:39

says that he loves autumn

play03:41

or that he loves autumn and poetry really loves autumn and poetry?

play03:44

Maybe he lies?

play03:45

And if he lies, does he feel

play03:47

remorse?

play03:49

And, eventually, why do we believe that

play03:52

an ability to make a fool of a person

play03:54

proves intelligence?

play03:58

The “I” in letter combination “AI”

play04:01

means “intelligence”

play04:03

Usually, one has in mind human

play04:04

intelligence.

play04:05

And usually one considers intelligence,

play04:07

at least the “Wikipedia” tells us that -

play04:09

as humans’ ability to

play04:11

analyze the outer world,

play04:13

to learn and to generate some

play04:14

rational behaviour.

play04:16

A long phrase, meaning nothing. If we throw out

play04:18

humans, hesitate about

play04:19

“rational”, we’ll have only “behaviour” left. May behaviour be an index of

play04:24

intelligence?

play04:25

I am a human. It is a crocodile.

play04:28

Both of us have very complex behaviour.

play04:31

Both of us can move,

play04:34

attack a prey, run away if the battle is

play04:36

unequal,

play04:37

but crocodiles can not plan

play04:39

future. A crocodile does not think:

play04:41

“Now I’ll kill this antelope,

play04:43

I’ll leave half of it for tomorrow, I’ll call my friends

play04:45

and we’ll discuss the problems of

play04:46

artificial intelligence."

play04:48

A crocodile does not make plans,

play04:50

he just implements his complex low-level

play04:52

predator behaviour.

play04:54

Mammals' brain structure has a

play04:55

crucial difference from the

play04:58

other animals’ brain structure. We have cerebral cortex.

play05:00

And this cortex perform many functions that

play05:04

we call intellectual

play05:05

and which include high-level memory.

play05:08

Lizards

play05:09

can not move through the labirynth in which

play05:11

the reward is hidden

play05:13

once more,

play05:14

they just seek everywhere again.

play05:16

In the same time mice

play05:18

having done the labirynth

play05:20

will at once go to the place where they found the

play05:22

reward last time, because they can memorize

play05:24

the way to this place.

play05:25

It is what the cortex is responsible for.

play05:29

We are all present here,

play05:30

we all seem to be in cosciousness

play05:33

and seem to be intelligent.

play05:35

I can’t be sure about you, but we are alike, and I believe that I’m in consciousness

play05:40

But still we implement actually no

play05:42

behaviour.

play05:43

You may do nothing, just lie

play05:46

and consider yourself to be intelligent.

play05:48

Thus,

play05:53

behaviour

play05:54

is not intelligence.

play05:57

And the most wonderful consequence of our

play05:58

intelligence is that we do not calculate an answer

play06:01

when we are asked a question.

play06:03

We know it, we remember it, well, you know this effect.

play06:06

And the calculation is made

play06:07

when we come to know

play06:09

the information necessary to

play06:10

give an answer in future.

play06:12

And this process is called learning.

play06:15

And

play06:16

I want to hold an experiment.

play06:20

I need your help.

play06:22

At first sight it may seem

play06:23

that I got crazy,

play06:24

but wait a little bit.

play06:26

So, I need your help. Now I will

play06:28

give you rather difficult

play06:30

tasks,

play06:31

you need to concentrate

play06:33

and answer in chorus

play06:34

in a very concentrated way.

play06:36

You’ll manage, I believe in you.

play06:37

You need silence and concentration.

play06:41

Are you ready?

play06:43

I feel that you are ready.

play06:48

It’s so fluffy and so nice

play06:49

il licks milk and catches mice

play06:51

it’s a cozy lovely pet

play06:52

who is it?

play06:54

It is a cat!

play07:00

Squirrel’s hollow’ s safe and good On an oak in the

play07:03

wood. Well done!

play07:05

If you want a chocolate cake, mix ingredients and

play07:09

bake!

play07:10

I can jump and I like carrot. Who am I? I am a… rabbit!

play07:17

With the help of such question we test children’s intelligence.

play07:20

Let us find out what is going on.

play07:23

First we need to understand the speech

play07:25

then to divide the sentences into words

play07:27

then to understand the meaning of the words

play07:29

and so on.

play07:30

And after that

play07:32

we need to make a prediction.

play07:35

We need, using some parametres,

play07:37

to complete a sentence,

play07:39

to predict the following word.

play07:41

According to this

play07:42

prediction algorithm

play07:44

our perception and our intellect

play07:46

generally

play07:47

function.

play07:49

A simple example is face recognition.

play07:51

Your eyes are moving in short

play07:55

hops, called saccades.

play07:57

When you suddenly find an eye,

play07:59

your brain says like: “wow, an eye!”

play08:01

And he adds:

play08:03

“Dear visual cortex, responding for the eye-movement,

play08:05

look around, there should be one more

play08:08

eye, nose and mouth,

play08:10

look closely."

play08:11

And now your eye which has found

play08:13

the first eye, has a particular task

play08:14

to find the second eye, and to find nose and mouth.

play08:17

And we quickly - blink-blink-blink - realize that

play08:19

it is a face.

play08:22

If you

play08:23

suddenly teleport to

play08:25

some other place, you’ll be ultimately

play08:27

surprised.

play08:27

If you close your eyes and then open them,

play08:29

you won’t be surprised.

play08:31

Your brain can predict that barely

play08:33

something could change during this blink.

play08:35

Another example of how

play08:38

prediction works

play08:39

is reading.

play08:40

Remember how you read

play08:43

in childhood.

play08:44

You read the first letter,

play08:47

the second one,

play08:48

you can see: m, o

play08:51

and you think: “phew, maybe, I’m lucky”, - mother!

play08:54

And they answer you:

play08:57

“no, motorbike!”

play08:58

Children so to say try to guess

play09:00

what is next, and parents critisize them for that

play09:02

but that’s how we actually learn to read.

play09:04

When an adult person reads

play09:06

a sentence, he moves over it

play09:07

in such hops,

play09:08

containing several words.

play09:09

What is our brain doing in this moment?

play09:11

Well you are actually relaxed,

play09:13

you are inside the story,

play09:15

your brain tries to predict

play09:17

what will happen next, what are the following

play09:19

words.

play09:20

Each such hop checks if everything is ok, is the prediction correct and if

play09:24

not

play09:24

he compensates everything,

play09:26

it corrects something

play09:29

and you read the text. It seems to you

play09:31

that everything comes into your head very smoothly

play09:33

but in fact you do make these hops.

play09:39

Let us get back

play09:40

to the question of the machines’ intelligence defining

play09:43

and recall how we define

play09:45

adults’ intelligence, because we have just

play09:46

proven that on children's level we are surely intelligent.

play09:50

IQ

play09:51

IQ... Test

play09:53

Ah, by the way here’s one more good example

play09:55

considerig how our brain works in prediction sphere. You look at the picture

play09:59

and you can see spots, spots, spots. Your brain tries to set up a hypothesis.

play10:03

It sets up a hypothesis and tries to find something

play10:05

similar to understand what is depicted there.

play10:07

As soon as the hypothesis is set up,

play10:09

you can not cease to see

play10:10

this Dalmatian dog.

play10:12

With a face, paws

play10:14

and body.

play10:15

As soon as your brain has set up a correct hypothesis,

play10:17

it can predict what is

play10:19

on the picture, it knows what to look at.

play10:22

(Laugh)

play10:23

Not everyone has such a talent.

play10:26

Well, adults’ intelligence

play10:27

defining.

play10:29

IQ test consists of the questions

play10:31

where you should continue a sequence.

play10:32

Sometimes this sequence consists of several ciphres, sometimes of several words or

play10:35

pictures.

play10:36

Sometimes it is some logical puzzles.

play10:38

But in any case it is an IQ test, where

play10:41

you should

play10:41

recognize a pattern

play10:43

and make a prediction.

play10:47

I offer to use an IQ test

play10:48

or some similar things instead of the

play10:50

Turing test, which is

play10:52

wonderful and nice but shows absolutely other things,

play10:55

to measure one’s/ something’s

play10:56

intelligence.

play10:58

And I want to finally represent

play11:00

the definition of the intelligence,

play11:02

which will be appropriate for us today.

play11:03

Intelligence is an ability

play11:05

to predict future

play11:07

and to create programs.

play11:08

Programs are not obligatory

play11:09

computer progrms, they may be

play11:11

just some easy programs, for instance,

play11:13

‘if there are bananas, buy, please,

play11:15

some bananas, and if there are no, then buy some apples’.

play11:17

It is a short computer

play11:19

program in which we make

play11:20

two predictions.

play11:22

There will be apples, almost for sure;

play11:24

if we are lucky there will be bananas.

play11:26

Bananas will be there less likely,

play11:29

we are not sure that they will be there. So, we make

play11:30

some predictions about future and according to them

play11:32

we predict some actions, we predict that

play11:34

we will have to act in this or that

play11:36

way.

play11:36

And

play11:38

the ability to create such algorythms

play11:41

and the ability to solve such tasks

play11:43

make up, in my opinion, intelligence.

play11:45

Let us find out how it works

play11:47

with humans

play11:50

and other living beings before we

play11:51

move on to computers.

play11:52

Here is an image of a brain.

play11:56

It consists,

play11:58

roughly speaking, of three sections.

play12:00

This section, this section and this

play12:03

section.

play12:04

This first section we share with

play12:06

fish, snakes and others, and

play12:09

it is responsible

play12:10

for the physiological

play12:12

behaviour of an organism,

play12:13

for us having pulse, breathing and not forgetting

play12:16

to do that.

play12:17

The next section

play12:18

we share with all the mammals and with

play12:21

some other animals.

play12:23

It is responsible for our complex hormone

play12:25

reactions - all this complex social

play12:27

behaviour, love, affection, friendship, everything around,

play12:31

for our non-adequate actions, for our adequate ac..

play12:33

And it is our adequate actions

play12:35

that the third section is responsible for.

play12:37

Some mammals

play12:38

have some traces of it, but

play12:40

it takes the most considerable part in humans’ brain.

play12:42

And this section is called ‘neocortex’.

play12:44

It is 2-millimetre’s thick,

play12:46

2-4 millimeters.

play12:47

And it is nearly of this size.

play12:49

Well, I won’t tell you that it is like a napkin or

play12:51

something. It is of this size.

play12:53

My brain is of that size.

play12:55

And that is how big neocortex is.

play12:56

And it is squeezed like that

play12:59

and is put into the cranium, that is why there are tubers.

play13:02

There is no other reason for that,

play13:04

it is not an architectural project,

play13:06

there’s no magic in those tubers.

play13:07

The neocortex is flat,

play13:08

it is just put into a brainpan,

play13:09

that is why there are tubers.

play13:11

It consists of four sections.

play13:14

Here we’ve got the left cerebral hemisphere, you see, the eye is here.

play13:19

It consists of the left hemisphere and the right hemisphere

play13:21

and besides,

play13:21

it is virtually divided

play13:23

into the front and the back part of neocortex.

play13:25

The back part responds mostly

play13:27

for the sensorial information processing, and the front part

play13:29

of neocortex responds mostly

play13:31

for various motor activity and

play13:33

for processing the behaviour itself.

play13:36

It is very homogeneous,

play13:38

a piece from here and a piece from here

play13:41

and a piece from here will be very

play13:42

similar.

play13:43

There will be the same neurons,

play13:45

the same composed layers,

play13:46

the same complicated connections.

play13:50

So, what is its structure

play13:53

if we look at it closer?

play13:55

If we make a cut - we have two millimetres here -

play13:57

you imagine, don’t you? We’ve taken a piece of neocortex

play14:00

play14:00

and we’ve made a cut.

play14:02

We can see different neurons - such cells -

play14:04

Merkulov has given

play14:05

a separate talk about neurons,

play14:07

so I won’t explain in detail.

play14:07

Roughly speaking, they have one output,

play14:09

many inputs,

play14:10

and, you see, they are all turned there

play14:12

and in that direction their amount grows.

play14:14

If we look closer, we will see some

play14:15

virtual layers.

play14:17

Look, there’s some differentiation.

play14:20

Let us look at these layers even

play14:22

closer.

play14:26

Usually they single out six layers,

play14:29

and besides,

play14:31

four first layers

play14:33

process information

play14:35

and the others are more likely to summarize it. And the last layer

play14:37

consists of, if you remember

play14:39

the last slide,

play14:39

greater amount of axons

play14:42

which lead to other neurons to

play14:45

the other parts of neocortex. That is, we have

play14:47

such a column.

play14:48

Why do we need to know it and why do I show you

play14:50

neocortex and neurons?

play14:52

This thing

play14:53

is a piece of our neocortex,

play14:56

having six layers,

play14:57

it is of two millimetres.

play15:00

These pieces of neocortex which are very

play15:02

homogeneous and very similar

play15:04

are connected hierarchically.

play15:06

That is, one piece is connected with its output with

play15:08

some other piece,

play15:10

those pieces are connected with

play15:11

some other pieces and they make up a kind of hierarchy,

play15:13

so, all these rectangles

play15:15

are the pieces of neocortex of some

play15:17

size,

play15:18

which have a great amount of inputs and

play15:21

less outputs, less outputs, less outputs.

play15:23

This structure

play15:25

transfers some abstract things into some

play15:27

more specific things. Let us

play15:29

examine this process through

play15:31

reading.

play15:32

We read the word “mother”.

play15:34

We have the lower layer

play15:36

which accepts the information

play15:37

from our visual

play15:39

receptors.

play15:41

And this lower layer can do

play15:43

some easy things. There is a big

play15:45

group or neurons in it,

play15:47

a huge family (this small piece)

play15:50

which can distinguish

play15:51

this kind of lines.

play15:53

A piece next to it

play15:55

can distinguish this kind of lines,

play15:56

another one - this kind of lines.

play15:58

Now if they are in the correct order,

play16:00

these pieces get activated,

play16:02

and on the second or the third level

play16:04

we already can distinguish letter ‘A’.

play16:07

If we have found a letter, having simultaneously

play16:09

this line, this line and

play16:11

this line,

play16:12

then on the next level we recognize letter ‘A’.

play16:15

Here we can

play16:16

already recognize

play16:17

syllables, there we recognize words,

play16:19

and so on, and so on and so on. Why do we need to know it?

play16:22

We are now focused on

play16:24

recogniton, what does this have to do with the intelligence?

play16:26

It appears a bit later,

play16:28

because

play16:29

you remember, we have just seen

play16:30

all that

play16:31

things, responsible for

play16:32

recognition, which are interconnected

play16:34

into more high-level things

play16:36

and even more high-level things

play16:38

and even more high-level things.

play16:39

When I say the word “mother” or when I read the word “mother”

play16:42

or when I think about my mother

play16:44

or when something reminds me my mother,

play16:46

let it be Mom’s shoes,

play16:48

quite different information comes

play16:49

through the inputs:

play16:51

it may be either visual information or audio

play16:53

but in all cases you will eventually recall

play16:55

the same image of your mother from your brain.

play16:58

When you hear me talking about your Mom

play17:00

or read me talking about you Mom,

play17:02

you think about the same Mom,

play17:03

you see?

play17:04

Thus, all these sections

play17:06

are connected in the end with high-level

play17:08

abstractions

play17:09

and the arrows go into both directions.

play17:13

What are the characteristics of all this structure?

play17:15

First of all,

play17:17

this structure keeps the

play17:19

sequences of patterns.

play17:21

That is, the letters in the word “mother” are arranged in some

play17:23

sequence.

play17:24

If I start singing some melody

play17:27

which you know,

play17:28

you will be able to continue from the place I stopped,

play17:30

but you don’t the member the whole song, you can

play17:32

take up from this place.

play17:33

You can not

play17:35

start singing it from a random sound,

play17:37

can not sing it from the end to the beginning,

play17:39

you see. There is a sequence

play17:40

and there is direction in which we

play17:42

read this sequence.

play17:45

Our memory works in associated way:

play17:47

in order to recall something

play17:49

we need to give to an input something

play17:52

similar to what we want to recall.

play17:54

play17:55

You do not keep your Mom in your head all the time.

play17:57

But as soon as I say “mother”,

play17:58

something connected with the word “mother”

play18:00

gets activated in your brain.

play18:01

When you try to recall some

play18:03

fact,

play18:03

it is very helpful to enumerate synonyms or associations.

play18:05

play18:07

In such a way you activate some

play18:09

neurons close to this fact and

play18:10

you recall this fact.

play18:13

Thus, our memory works with associations.

play18:15

We

play18:16

need some association to match it

play18:18

with some association.

play18:21

Our memory, due to the great amount of layers,

play18:23

there may be much more of them,

play18:25

keeps the patterns

play18:26

in an unchanged form.

play18:28

Look, here is letter ‘A’.

play18:30

And it is obvious for all of us, that it is letter ‘A’

play18:33

but we have just put a sheet on its side,

play18:34

you see.

play18:35

But in fact this letter ‘A’ and this letter ‘A’

play18:37

consist of compeletely different components.

play18:40

Our memory, using many layers,

play18:42

eventually turns all these letters into

play18:44

some abstraction of letter “A”,

play18:47

and it is of no importance after that, how it is written.

play18:49

It is easy to understand on the example of letters,

play18:51

but it is the same with all the other things. When you look at

play18:53

me like that,

play18:55

when you look at me like that,

play18:57

you do not have any difficulties to recognize

play18:59

the same person, though

play19:01

in such a way I don’t look like myself at all.

play19:07

Ok, what does it result in?

play19:11

Since 2007 approximately we

play19:13

witness a huge fresh leap

play19:16

in neuron networks development (which have been

play19:17

developing for the last 50 years),

play19:19

called Deep learning.

play19:21

What is it about?

play19:23

Its essence, in a couple of words, is in multilayer

play19:25

hierarchic neuron networks, similar to our

play19:27

neocortex.

play19:28

Multilayer neuron networks

play19:30

are known since long ago,

play19:31

approximately since the middle-the end

play19:33

of the twentieth,

play19:36

but there was a range of difficulties and problems, connected

play19:38

with their learning.

play19:39

Usually,

play19:41

simple neuron networks are educated in a

play19:43

comparatively easy way. Imagine, here is a simple neuron network:

play19:44

we have an input,

play19:46

we have some outputs

play19:48

and now we need to tune

play19:49

these inputs and these outputs in such a way,

play19:51

that with some coefficients some signal on an input

play19:53

lead to some signal on the outputs.

play19:54

When we have a greater amount of the layers,

play19:57

the quantity of the elements taking part in the process becomes so high,

play19:59

that the classical

play20:01

methodics of learning do not work.

play20:03

In 1995 a new mathematical machine was invented.

play20:05

At the beginning of 2000-s

play20:06

was developed a speсific soft

play20:08

which could do that, and in the same time

play20:10

appeared the Internet,

play20:11

developed the Internet.

play20:14

The Internet has lead us, sapienses to

play20:16

furious generation of content:

play20:19

various images,

play20:21

videos and so forth. This content appeared to be

play20:23

this very thing, necessary for

play20:25

neuron networks learning.

play20:27

It needs to learn on some material.

play20:29

And Google, having bought Youtube in 2012

play20:33

first of all -

play20:33

what would you do? -

play20:34

certainly, it took 16 000 computers,

play20:37

installed a neuron network , set it at Youtube.

play20:39

They were doing something for a week (there was no

play20:42

specific task, just Youtube and neuron network)

play20:44

play20:45

so, a week later

play20:47

they said “We found object “A”,

play20:49

it is noticed in all those videos.

play20:51

It happened to be homo sapiens.

play20:52

“We found object “B” - it occurs in all those videos. This happened to be a cat.

play20:57

In a week’s term a neuron network came to know

play20:59

how to distinguish people from cats

play21:01

and how to find cats in a video,

play21:02

though there was no task to find cats.

play21:05

Cats just seem to be popular enough

play21:06

for it to decide that cats are important

play21:09

for sapienses.

play21:11

Simultaneously, the same neuron network,

play21:14

absolutely the same, the same abstract of code,

play21:16

learned on different test-kits

play21:17

may perform different

play21:20

tasks. Assume,

play21:21

often we can teach

play21:23

the same piece of code to recognize

play21:24

pictures

play21:25

and, with minimal changes,

play21:27

recognize sound.

play21:28

These are quite different tasks, but remember our neocortex.

play21:32

It is absolutely homogeneous,

play21:33

its sections complete different tasks

play21:35

and it is almost identic everywhere.

play21:37

play21:37

Google’s cars

play21:38

have already run more then a million kilometres -

play21:41

when I gave a talk this summer I said:

play21:43

“and not single a car crash has taken place”,

play21:45

but after that there was a crash,

play21:47

they were stricken, they are not guilty.

play21:49

So,

play21:51

in 2015, this year

play21:54

many interesting things have happened. Since 2013,

play21:57

play21:59

nearly since 2013 the amount of mistakes

play22:00

made by the AI

play22:02

in the process of different items recognition

play22:03

dramatically diminished.

play22:06

And,

play22:09

it moved, moved, moved and here

play22:12

in 2013 it considerably decreased

play22:13

and this is 100% of

play22:15

accuracy.

play22:16

So,

play22:16

we are in this point.

play22:18

Machines now recognize pictures

play22:20

in average better than people. Computers

play22:22

defeated people in several competitions

play22:24

concerning picture recognition,

play22:26

including finding a cat in a picture,

play22:29

including road signs recognition,

play22:31

and so on, and so on,

play22:33

and so forth.

play22:36

Why am I telling al these things?

play22:41

The important question is as follows.

play22:43

When we compare and speculate about

play22:45

the intelligence, the foolness and such things,

play22:48

we usually

play22:49

compare a rural fool

play22:52

and a Nobel prize

play22:57

winner.

play23:01

Here we need to understand

play23:03

that even a rural fool is dramatically, considerably much more clever than any other non-homo sapiens.

play23:10

If we take a mouse,

play23:12

mouse is a mammal, mice have a thin

play23:14

layer of neocortex - they can do

play23:16

a lot of cool things, they are really clever. If we take

play23:18

a mouse,

play23:19

its intelligence leaves much to be desired, its

play23:21

difference from a rural’s fool intelligence is enormously huge, still the difference between a fool and a

play23:23

genius is tiny.

play23:25

If we would like to compare some other animals,

play23:27

they will arrange like that

play23:28

and a lot of them will be sillier than a mouse.

play23:32

And when we look at this picture,

play23:34

we need to understan, that the artificial intelligence

play23:35

existing now

play23:36

is, in average, more primitiv, than the mouse’s one.

play23:38

Mice are cool.

play23:39

Contemporary artificial intelligence is a bit less

play23:41

cool than a mouse’s one,

play23:42

but it improves itself.

play23:45

One day it will overcome mouse,

play23:46

then we will make more efforts for a long time

play23:49

and artificial will overcome

play23:51

primates

play23:52

and then some moment artificial intelligence

play23:53

will reach a rural fool’s level.

play23:57

And in the next moment after that moment

play24:00

just in a couple of days

play24:01

artificial intelligence will overcome a genius.

play24:04

This difference is not so huge as

play24:06

that one.

play24:11

And very soon, in a couple of days after

play24:13

the day when artificial intelligence reaches

play24:15

the fool’s level, the situation will be like that.

play24:17

And this difference is really

play24:18

huge.

play24:19

Why will it happen like that?

play24:22

Now I will show you an example of a

play24:24

normal process.

play24:25

Here is a diagram of GDP for the last 10 thousand years.

play24:33

Moreover, it is a normal process, many

play24:37

things in the Universe move like that.

play24:38

If we take the figures away

play24:39

we will get an amount of iron mined on our planet for any

play24:44

amount of years, and so on.

play24:45

Many thing related

play24:47

to technological progress look

play24:48

quite the same. At first there is nothing and then, well

play24:50

you know, don’t you?

play24:57

What am I getting at?

play24:58

I’m getting to the fact, that now we are

play25:00

approximately here.

play25:02

People’s productivity

play25:03

grows step by step,

play25:05

we learn, a 100 years ago

play25:07

education became whole-planet

play25:09

then higher education became available for everyone,

play25:11

we have better and better and better results and people become

play25:13

more and more intelligent.

play25:14

At the time we didn’t have computers,

play25:16

we were already cool,

play25:19

we were given odds.

play25:20

First computers didn’t exist,

play25:21

then they became cooler and cooler

play25:23

then they are on this level.

play25:25

And the moment they reach this point

play25:27

we will be hardly able to bother them anyhow.

play25:33

Maybe, AI invention

play25:35

will be last humanity’s

play25:36

invention.

play25:39

Why?

play25:41

Chimpanzee is strong.

play25:42

Chimpanzee is really strong,

play25:44

it is like two times stronger

play25:46

than an adult man. If a dozen of chimpanzees

play25:48

will come in now

play25:52

they will for sure defeat us.

play25:54

I am just ready to bet.

play25:55

There are two doors here, behind me and right there,

play25:58

we will run to these doors

play26:00

from everywhere.

play26:02

We will be helpless against

play26:04

chimpanzees.

play26:05

But chimpanzees can not turn off

play26:07

people.

play26:08

They do not have such a button.

play26:09

They can do nothing. And all chimpanzees’ lifes

play26:11

on our planet

play26:12

are connected first of all with

play26:14

humans’ intention.

play26:16

We can not turn off the internet,

play26:18

the internet has been invented recently

play26:19

it does not have its own intelligence

play26:21

but there’s no button “Turn the Internet off”.

play26:22

In the same way there won’t be a button

play26:24

“Turn the AI off”.

play26:26

And we well be like those chimpanzees

play26:28

which are much stronger then us -

play26:31

we will also be stronger than that iron box - we can surely beat it,

play26:34

but the button “Turn AI

play26:36

off” won’t exist and even hackers

play26:38

constantly find weak points

play26:40

in computer systems.

play26:41

AI and hackers will find them much

play26:43

faster. Even if

play26:44

we take this iron box, disconnect it

play26:47

from the internet, put it into other box,

play26:49

hackers

play26:51

with the help of social engineerins, bribes and other people

play26:53

will be able to open those

play26:55

iron boxes, disconnected from the

play26:56

internet. Why should AI fail to do that?

play26:59

It may set contact with the maintenance stuff,

play27:00

hire people.

play27:02

I think that if someone will try

play27:03

to hurt really smart AI

play27:06

with people’s hands,

play27:07

it will hire other people

play27:09

to protect it from those dangerous for it.

play27:11

Well, you’ve got the idea.

play27:16

They say that something like that

play27:18

took place during the industrial

play27:19

revolution.

play27:20

play27:22

During the industrial revolution, remember,

play27:24

luddites and all those things.

play27:26

And people decided: “Let us ruin factories

play27:28

because if we install machines everywhere,

play27:29

there won’t be any work for us."

play27:32

Machines were being installed and installed

play27:34

and finally they were installed everywhere.

play27:36

And it occurred that people still do have what to do.

play27:39

What is the difference between AI evolution

play27:40

and the evolution of machines?

play27:44

The most part of people in different countries

play27:46

(80 per cent)

play27:47

are now performing the tasks

play27:49

which computers will soon do better

play27:51

than people.

play27:53

Computers will answer people’s questions

play27:56

more accurately,

play27:57

will drive better,

play27:59

will better answer questions in call-centres,

play28:01

will better identify criminals

play28:02

on video surveillance cameras,

play28:04

will sell goods in supermarkets

play28:06

better.

play28:07

Well, they will do better

play28:09

almost everything that most people do now.

play28:11

If people will be substituted by the computers

play28:13

so what should all these people do?

play28:15

Taking into the account the fact that

play28:16

AI and computers’ evolution

play28:17

doesn’t seem to be a process

play28:19

which may

play28:20

finalize.

play28:22

In contrast to machine evolution

play28:24

when we have equipped every

play28:25

factory with a mechanized lathe

play28:27

and that was actually

play28:28

all

play28:29

we could do.

play28:35

And we.. (this “thank you” is not yet for you)

play28:38

It is important to understand, that

play28:39

the problem of “odd” people

play28:41

should be solved now, immediately.

And being more clever or working harder

play28:47

won’t change anything

play28:48

because we should remember that:

play28:49

here is our productivity’s

play28:51

growth,

play28:52

and here is the computers’ one

play28:53

what means that we won’t

play28:55

be able to become more intelligent and efficient than them again.

play28:57

play28:59

One of the possible ways of this problem solving,

play29:01

the first one that comes to my mind

play29:03

is to make job independent from salary

play29:06

so people should work because they like it

play29:08

and get money because all the

play29:09

homo sapienses get money via delivery.

play29:13

Well, either it may be manual labour higher appreciation,

play29:15

with the growing need to buy the products

play29:18

made by homo sapienses and not by

play29:20

soulless machines and so on.

play29:22

But all these ways are rather controversial

play29:24

and some new methods should be

play29:26

invented.

play29:28

I want to summarize:

play29:30

we won’t be able to control and restrict AI

play29:31

play29:33

if it appears.

play29:34

And it will appear for sure

play29:36

in the future 50 years or sooner.

play29:39

The only thing that can help us somehow

play29:41

is having common goals

play29:43

with the AI and

play29:45

being allies with it.

play29:48

AI development is a very

play29:50

difficult task, but

play29:52

AI which won’t destroy the humanity development is

play29:54

an even more difficult one.

play29:56

And it is very important

play29:57

that these tasks were solved in a

play29:59

correct order.

Thanks a lot!
