Transcripts
In this video
we'll be covering what generative AI is.
What machine learning is and the
different types of machine learning,
what LLMs are what's deep learning
and all the other jargon you hear
when you think about generative AI.
This is Suraj and he's a non coder.
This is Siddhant and he's a pro coder.
Siddhant, every reel, blog post and
tweet is about generative AI today.
Even Ola's founder launched the AI platform.
EY says generative AI is going to add
1.5 trillion to the Indian economy.
Sam Altman says that this is a bigger
revolution than the internet itself.
So what is generative AI?
Let's break it down.
The term is made up of two things,
Generative and AI.
So Generative refers to creating new
content such as text, images, videos.
AI stands for artificial intelligence,
which is a branch of computer science.
That deals with making computers
and machines smart enough so
that they can behave like humans.
For example, understanding language,
recognizing objects and patterns.
And when this AI starts Generating new
content, that is called Generative AI.
Okay
but why is everybody
talking about it now?
What happened?
What changed?
It's a combination of these three things,
hardware, software, and data.
Since late two thousands, GPUs have
increasingly replaced CPUs in all the AI tasks
but what exactly is A GPU?
The GPU stands for Graphics Processing Unit.
Think of GPU as a team of
workers in a factory and A CPU.
As A CEO.
The CPU like the CEO
by nature is a generalist.
Which is really good at performing
complex tasks and decision making.
It can handle a variety of different
jobs, but it works on them one at a time.
On the other hand, GPUs as factory workers
aren't as versatile as the CEO, but they are
great at doing simpler, repetitive tasks.
And importantly, there are a lot of them
so they can work on many tasks at the same time.
This is similar to how a GPU works.
It has hundreds or even thousands of smaller,
less complex processing cores that
can handle many operations simultaneously.
This makes the GPU an obvious choice
for handling graphics and video games.
So whenever you play a video game
or watch a 4k movie.
Your GPU quickly renders images and videos by
processing lots of calculations in parallel.
It's like having an army of workers painting
a huge wall at the same time, while the
CPU would be like one person carefully
painting detailed features on a small canvas.
Watch this demo of GPU vs CPU by NVIDIA.
So basically GPUs are like graphic
cards we use for gaming, right?
But how is it being used in AI?
So GPUs aren't only just for graphics.
Their ability to handle multiple operations
at once makes them ideal for tasks such as
artificial intelligence and machine learning.
In fact, NVIDIA reports that since the
introduction of GPUs, The performance
in AI has seen an extraordinary increase
improving by as much as
1000 times over the span of a decade.
Now, along with hardware improvements, there
have been notable development in AI research.
In 2016, a significant breakthrough
happened with the introduction of
transformers in a research paper
titled attention is all you need.
This is the foundation of
GPT-Generative Pre-Trained Transformer
which became the fastest growing consumer app.
of all time
Getting over 100 million monthly
users in just two months of launch.
GPD-4 even passed all the tough tests
like bar exams and your SATs.
But how did GPD pass the SATs and bar exam?
Even a normal person can't do that.
It's really difficult, right?
So this is because GPD was trained
on a large corpus of
Text data from the internet, including
including thousands of books
millions of articles and Â
the entirety of Wikipedia.
So you'll know everything about each topic.
Exactly.
Okay.
I'm starting to understand what
Gen AI is all about, right?
But what is machine learning
AI got to do with this?
So let's understand this one by one.
AI is a broad discipline.
AI to computer science is similar
to what physics is to your science.
Machine learning is a subset, or you can say
a type of AI that focus on building systems
that learns from data and behave like humans.
It is a program or system that trains
a model from input data that trained
model can make useful predictions from
new or never before seen data drawn from
the same one used to train the model.
Machine learning gives the computer
the ability to learn without explicit
programming, just like how human learns.
And two of the most common types
of machine learning models are
unsupervised and supervised models.
The key difference between the two
is that with supervised models.
We have labels.
Label data is the data that comes with
a tag, like a name, a type, or a number.
Unlabeled data is the data
that comes with no tags.
so what I'm understanding is So what I'm understanding is that
that supervised
machine learning
is when the data comes
with tags and labels
and the machine knows
what it's learning,
like it's a cat and dog and everything,
it knows the correct answers.
The unsupervised machine learning
is when the data is unlabeled,
so it's learning those structures
and the patterns behind the data
That's exactly correct.
You perfectly nailed it Suraj
I knew it.
But now I'm a little confused.
What is machine learning
and what are models?
So machine learning is a field of study
and you can think of it as a process.
And machine learning
model is a specific
output of this process.
it is what machine
learning system creates
after being trained on the data,
this model contains the knowledge
and the patterns
learned from its training.
Got it! That's machine learning.
But what about deep learning?
So deep learning
is a subset of machine learning.
You can think of it
as one more type of machine learning
that uses artificial neural networks,
What are Artificial Neural Networks?
So Artificial Neural Networks
are inspired by the human brains.
They are made up of
interconnected nodes called neurons
that can learn to perform tasks
by processing data
and making predictions.
Deep Learning models
typically have many layers of neurons,
which allows them to learn more complex
patterns than traditional Machine
Learning models.
And neural networks can be both labeled
and unlabeled data.
In semi supervised learning,
a neural network is trained
on a small amount of labeled data
and a large amount of unlabeled data.
But labeled data
helps the neural network
to learn the basic
concepts of the task.
While the unlabeled
data helps the neural networks
to generalize the new examples.
Okay.
Is this similar to generative AI?
Yes, that's correct.
I know that's a very good observation.
so generative. A.I.
is a type of deep learning
which uses
these artificial neural networks
and can also process
labeled and unlabeled data
to generate new content.
I guess this is all pretty much.
Humans also learn.
You go to school
where you learn the label data
and then you go to the real world
and you learn the unlabeled data.
And at the end of the day,
you come here
and generate content, right?
so where do alums
and all come into this?
so large language
model are also type of deep
learning models.
these models are large
both in terms of their physical size
and also the amount of data
they have been trained on.
now, to understand
how everything is connected.
Let's move one
step above deep learning and LLMs
based on the type of output
they generate.
Machine learning
models can be divided into two types
Generative and Discriminative
A discriminative model
is used to classify or predict labels
for data point.
For example,
a discriminative model
could be used to predict
whether or not an email is a spam.
Here, spam is the label
and email is the data point.
Discriminative models
are typically trained
on a dataset of these labeled
data points,
which means while training
we will show model
all the Emails which look like spams
so that it learns the relationship
between the label and data point.
Once a discriminative model is trained,
it can be used to predict the label
for new data points.
In health care, a discriminative model
could be used to predict
whether a patient
has a specific disease
or not based on their symptoms
and test results.
for example,
it might analyze blood test data
to predict the likelihood of diabetes.
on the other hand,
a generative model
is designed to understand and reproduce
the characteristics of data
rather than just
distinguishing between
different categories or labels.
Suppose
we are training a generative model
with pictures of cats.
the models
task is not just to identify
whether an image is a cat or not.
Instead,
it learns the features that make up cat
images, shapes, colors,
textures and patterns. Common to cats.
It understands these features
so well that it can generate
new images of cats that look realistic
but do not replicate
any specific cat
from the training data.
Large language
models are a specific type
of generative models
focusing on the language, and GPT
is one of the example
of generative large language model.
Okay, now I have a good idea
of what gender is all about.
Now I want to start using this.
I want to start building models.
So where do I start for that?
Well, lucky for you,
I'll be giving you the roadmap
to become a GenAI
engineer in this video.
