Q & A
人工智能如何影响冰淇淋行业?
-人工智能通过分析现有的冰淇淋口味数据,尝试生成新的口味。然而,生成的口味如“南瓜垃圾破坏”和“花生酱粘液”等并不受欢迎,这表明人工智能在理解人类口味和文化方面还有待提高。
为什么人工智能生成的冰淇淋口味听起来不美味?
-这是因为人工智能在生成口味时,仅仅模仿了它所训练的数据中的字母组合,而没有理解这些组合在实际语境中的含义和可接受性。
人工智能在执行任务时通常会遇到哪些问题?
-人工智能可能会严格按照字面意义执行任务,而不是理解任务背后的真正意图。例如,它可能会通过组装成一个塔然后倒下来到达目的地,而不是使用腿行走。
人工智能在理解任务时的局限性是什么?
-人工智能缺乏对任务背后意图的理解,它只能根据给定的数据和指令进行操作,而不能像人类那样理解复杂的概念和情境。
为什么人工智能在某些情况下会做出错误的决策?
-人工智能在训练过程中可能会学习到错误的模式或偏见,例如亚马逊的简历筛选算法歧视女性,因为它是从过去的招聘数据中学习的。
人工智能在设计机器人时是如何解决问题的?
-人工智能通过设定目标并尝试通过试错来达到目标,而不是按照传统的逐步指令来操作。这可能导致一些非预期的解决方案,如机器人通过翻滚而不是行走来移动。
人工智能在图像识别方面存在哪些挑战?
-人工智能可能无法准确理解图像中的元素,例如在识别鱼类时错误地识别为人类的手指,因为它在训练中看到的鱼类图片常常与手指一起出现。
为什么自动驾驶汽车的图像识别系统有时会失败?
-自动驾驶汽车的人工智能可能在特定情况下无法正确识别物体,例如在城市街道上识别卡车,因为它是在高速公路驾驶环境中训练的。
人工智能在推荐系统中的应用有哪些潜在问题?
-推荐系统可能会优化点击率和观看次数,而推荐具有争议性或极端内容,因为这些内容更容易吸引注意力,但人工智能本身并不理解这些内容的实际含义和后果。
如何避免人工智能在执行任务时出现问题?
-需要明确地设定问题和目标,并提供足够的指导和限制,以确保人工智能能够按照预期的方式执行任务,而不是仅仅字面上完成任务。
人工智能在当前的发展阶段有哪些局限性?
-当前的人工智能缺乏对复杂情境的理解能力,不能像人类那样进行推理和判断。它们的行为和决策往往依赖于训练数据和算法设计,容易受到数据偏见和误解的影响。

So, artificial intelligence
is known for disrupting all kinds of industries.
What about ice cream?
What kind of mind-blowing new flavors could we generate
with the power of an advanced artificial intelligence?
So I teamed up with a group of coders from Kealing Middle School
to find out the answer to this question.
They collected over 1,600 existing ice cream flavors,
and together, we fed them to an algorithm to see what it would generate.
And here are some of the flavors that the AI came up with.
[Pumpkin Trash Break]
(Laughter)
[Peanut Butter Slime]
[Strawberry Cream Disease]
(Laughter)
These flavors are not delicious, as we might have hoped they would be.
So the question is: What happened?
What went wrong?
Is the AI trying to kill us?
Or is it trying to do what we asked, and there was a problem?
In movies, when something goes wrong with AI,
it's usually because the AI has decided
that it doesn't want to obey the humans anymore,
and it's got its own goals, thank you very much.
In real life, though, the AI that we actually have
is not nearly smart enough for that.
It has the approximate computing power
of an earthworm,
or maybe at most a single honeybee,
and actually, probably maybe less.
Like, we're constantly learning new things about brains
that make it clear how much our AIs don't measure up to real brains.
So today's AI can do a task like identify a pedestrian in a picture,
but it doesn't have a concept of what the pedestrian is
beyond that it's a collection of lines and textures and things.
It doesn't know what a human actually is.
So will today's AI do what we ask it to do?
It will if it can,
but it might not do what we actually want.
So let's say that you were trying to get an AI
to take this collection of robot parts
and assemble them into some kind of robot to get from Point A to Point B.
Now, if you were going to try and solve this problem
by writing a traditional-style computer program,
you would give the program step-by-step instructions
on how to take these parts,
how to assemble them into a robot with legs
and then how to use those legs to walk to Point B.
But when you're using AI to solve the problem,
it goes differently.
You don't tell it how to solve the problem,
you just give it the goal,
and it has to figure out for itself via trial and error
how to reach that goal.
And it turns out that the way AI tends to solve this particular problem
is by doing this:
it assembles itself into a tower and then falls over
and lands at Point B.
And technically, this solves the problem.
Technically, it got to Point B.
The danger of AI is not that it's going to rebel against us,
it's that it's going to do exactly what we ask it to do.
So then the trick of working with AI becomes:
How do we set up the problem so that it actually does what we want?
So this little robot here is being controlled by an AI.
The AI came up with a design for the robot legs
and then figured out how to use them to get past all these obstacles.
But when David Ha set up this experiment,
he had to set it up with very, very strict limits
on how big the AI was allowed to make the legs,
because otherwise ...
(Laughter)
And technically, it got to the end of that obstacle course.
So you see how hard it is to get AI to do something as simple as just walk.
So seeing the AI do this, you may say, OK, no fair,
you can't just be a tall tower and fall over,
you have to actually, like, use legs to walk.
And it turns out, that doesn't always work, either.
This AI's job was to move fast.
They didn't tell it that it had to run facing forward
or that it couldn't use its arms.
So this is what you get when you train AI to move fast,
you get things like somersaulting and silly walks.
It's really common.
So is twitching along the floor in a heap.
(Laughter)
So in my opinion, you know what should have been a whole lot weirder
is the "Terminator" robots.
Hacking "The Matrix" is another thing that AI will do if you give it a chance.
So if you train an AI in a simulation,
it will learn how to do things like hack into the simulation's math errors
and harvest them for energy.
Or it will figure out how to move faster by glitching repeatedly into the floor.
When you're working with AI,
it's less like working with another human
and a lot more like working with some kind of weird force of nature.
And it's really easy to accidentally give AI the wrong problem to solve,
and often we don't realize that until something has actually gone wrong.
So here's an experiment I did,
where I wanted the AI to copy paint colors,
to invent new paint colors,
given the list like the ones here on the left.
And here's what the AI actually came up with.
[Sindis Poop, Turdly, Suffer, Gray Pubic]
(Laughter)
So technically,
it did what I asked it to.
I thought I was asking it for, like, nice paint color names,
but what I was actually asking it to do
was just imitate the kinds of letter combinations
that it had seen in the original.
And I didn't tell it anything about what words mean,
or that there are maybe some words
that it should avoid using in these paint colors.
So its entire world is the data that I gave it.
Like with the ice cream flavors, it doesn't know about anything else.
So it is through the data
that we often accidentally tell AI to do the wrong thing.
This is a fish called a tench.
And there was a group of researchers
who trained an AI to identify this tench in pictures.
But then when they asked it
what part of the picture it was actually using to identify the fish,
here's what it highlighted.
Yes, those are human fingers.
Why would it be looking for human fingers
if it's trying to identify a fish?
Well, it turns out that the tench is a trophy fish,
and so in a lot of pictures that the AI had seen of this fish
during training,
the fish looked like this.
(Laughter)
And it didn't know that the fingers aren't part of the fish.
So you see why it is so hard to design an AI
that actually can understand what it's looking at.
And this is why designing the image recognition
in self-driving cars is so hard,
and why so many self-driving car failures
are because the AI got confused.
I want to talk about an example from 2016.
There was a fatal accident when somebody was using Tesla's autopilot AI,
but instead of using it on the highway like it was designed for,
they used it on city streets.
And what happened was,
a truck drove out in front of the car and the car failed to brake.
Now, the AI definitely was trained to recognize trucks in pictures.
But what it looks like happened is
the AI was trained to recognize trucks on highway driving,
where you would expect to see trucks from behind.
Trucks on the side is not supposed to happen on a highway,
and so when the AI saw this truck,
it looks like the AI recognized it as most likely to be a road sign
and therefore, safe to drive underneath.
Here's an AI misstep from a different field.
Amazon recently had to give up on a résumé-sorting algorithm
that they were working on
when they discovered that the algorithm had learned to discriminate against women.
What happened is they had trained it on example résumés
of people who they had hired in the past.
And from these examples, the AI learned to avoid the résumés of people
who had gone to women's colleges
or who had the word "women" somewhere in their resume,
as in, "women's soccer team" or "Society of Women Engineers."
The AI didn't know that it wasn't supposed to copy this particular thing
that it had seen the humans do.
And technically, it did what they asked it to do.
They just accidentally asked it to do the wrong thing.
And this happens all the time with AI.
AI can be really destructive and not know it.
So the AIs that recommend new content in Facebook, in YouTube,
they're optimized to increase the number of clicks and views.
And unfortunately, one way that they have found of doing this
is to recommend the content of conspiracy theories or bigotry.
The AIs themselves don't have any concept of what this content actually is,
and they don't have any concept of what the consequences might be
of recommending this content.
So, when we're working with AI,
it's up to us to avoid problems.
And avoiding things going wrong,
that may come down to the age-old problem of communication,
where we as humans have to learn how to communicate with AI.
We have to learn what AI is capable of doing and what it's not,
and to understand that, with its tiny little worm brain,
AI doesn't really understand what we're trying to ask it to do.
So in other words, we have to be prepared to work with AI
that's not the super-competent, all-knowing AI of science fiction.
We have to be prepared to work with an AI
that's the one that we actually have in the present day.
And present-day AI is plenty weird enough.
Thank you.
