Hello and
welcome back to the course on Deep Natural Language Processing.
And today we're going to talk about the types of natural language processing.
So we've got two Venn diagrams here.
Or we've got a Venn diagram with two circles in it.
And we are going to look
at the different areas of,
natural language processing that are going to come up in this course.
So on the left we've got natural language processing overall.
And this refers to the whole circle on the left.
So the reason why we've called it in just this green part is because that's the
non-overlapping part.
So we know that anything in here, is just natural language processing.
We followed with disregard to this second circle.
But, natural language processing is indeed everything that is in this first circle.
Then we've got on the right deep learning.
So these are all algorithms that have something
to do with neural networks, deep learning.
basically anything that's called a deep learning algorithm falls in here.
They don't have to be natural language processing.
They can be, classification.
they can be anything.
So they can be that's in deep learning or here.
And natural language processing is any algorithm, any model
that has something to do with processing of natural language,
into machine terms.
And then finally
in the overlap we have deep NLP.
So these are models which have to do with natural language processing,
but also which are deep learning models which are neural network models.
And yeah.
So that's the part that we're going to be aiming for.
But it's also very good to have a visibility of all three,
because in this course we will be talking about some models that fall just in here.
And then we'll be talking about models here.
And it'll be good to compare and see how the world has changed over time,
and why these models are often better than these models.
and the other thing to note here is that the size of these diagrams
is not reflective of the importance or the volumes of these different fields.
So, I just, I set circles of the same size simply because we want
a visual representation of, of the overlap and that these fields exist.
But don't, take the size into account.
It's not to scale at all.
And, finally, there is another part,
another part of this event diagram, which is very important to us.
And it is this part over here, a
sub, section of a deep NLP called a sequence to sequence.
So sequence to sequence models are the most cutting edge, the most
powerful models that exist right now for, natural language processing.
And that's what we're going to be looking at.
So as you'll see throughout this course, we will make our way
through the natural language processing side of things into deep NLP.
And then we will go into sequence to sequence.
It'll be a fun and exciting journey.
and the other thing that I wanted to mention is you will also notice
that throughout this course, even though it's focused
on chatbots, we won't be talking about just chat bots.
We'll be looking at different examples of, how these models
from here and from here and from here can be applied to different things.
Because the applications are huge.
We can talk, we can apply them in, natural, in neural machine translation.
We can apply them, in image captioning.
We can apply them in, speech recognition,
questions and answers, text summarization, lots and lots of models.
So, we will be looking at different ones and they will be of different types.
So this map will come in handy as we go through the course.
And it will be popping up here and there.
So I think it was very important for us to set the foundation, right.
So that now we're ready to proceed.
And I can't wait to see you on the next tutorial.
And until then, enjoy a deep and natural language processing.
