Hey guys welcome to the session by Intellipaat.
Now you guys must have come across the terms artificial intelligence, machine
learning and deep learning and numerous questions would have popped into your
head, what exactly are they how they are different from each other and what
purpose do they serve. So today's session would help you to understand the
difference between these three terms so I'll start off by asking you a very
simple question, so tell me what is it that makes humans intelligent, well we as
humans can think learn and make decisions and that is what what makes us
intelligent. Now imagine if machines can show human-like intelligence, a machine
which can think and make decisions like humans, that is truly amazing isn't it? So
artificial intelligence is basically that field of computer science which
emphasizes on the creation of intelligent machines which can work and
react like humans. So now that we know what artificial intelligence is, let's see
where do machine learning and deep learning fit in. So you can consider
artificial intelligence to be the broader umbrella and machine learning
and deep learning to be a subset of it or you can also say that machine
learning and deep learning are a means to achieve artificial intelligence. Now
let's see what machine learning is. So machine learning is basically the subset
of artificial intelligence where we teach a machine how to make decisions
with the help of input data so we'll understand machine learning with this
little example. So what do you see over here, what is this exactly? well it's a bird
and what about this, this again is a bird and this? well this too is a bird. Now how
do you all of these are birds? Well as a kid you might have come across a picture
of a bird and you would have been told by your kindergarten teacher or your
parents that this is a bird and your brain learned that anything which looks
like that is a bird and that is how our brain functions. But what about a machine
now if I take in this image of the bird and feed it to a machine will it be able
to identify it as a bird? So this is where machine learning comes in so what
I'll do is I'll take all of these images of the birds and keep on feeding them to
the machine until it learns all the features associated with it and
once it learns all the features associated with it
I'll give it new data to determine how well it has learnt or in other words
first I'll feed in training data to the machine so that it can extract or learn
all the features associated with the training data and once the learning is
done I'll give it new data or the test data to determine how well the learning
is done and this is the underlying concept of machine learning. Now let's
head on to deep learning, so deep learning is the subset of machine
learning where we develop intelligent algorithms which mimic human brain. So
now the question which arises over here is how do we mimic human brain? Well to
answer that let me ask another question. So what is the brain composed of? Well a
brain is primarily composed of neurons Isn't it and these neurons send and
receive electrochemical signals so we have a neuron over here and the
electrochemical signals are received through the dendrite, the processing of
these signals is done in the cell body and the output of these input signals is
sent to other neurons to the axon and if our task is to mimic human brain all we
have to do is create artificial neurons and these artificial neurons work the
same way as biological neurons. So to implement deep learning
we'll have to create artificial neural networks and these artificial neural
networks comprise of an input layer, a hidden layer and an output layer so all
of the inputs are received through the input layer and the processing is done
in the hidden layer and the final output is received through the output layer and
to sum it up artificial intelligence is the broader umbrella, machine learning is
the sub set of artificial intelligence and deep learning is the sub set of
machine learning and machine learning and deep learning are basically methods
to achieve artificial intelligence. So guys this brings us to the end of the
session and do stay tuned to Intellipaat youtube channel for more such
