About This Course (C1W1L05)

Andrew Ng outlines Course 1 of a five-course Deep Learning Specialization. Over four weeks you'll learn deep learning fundamentals, neural network programming, build a single-hidden-layer network, then a multi-layer deep network. Each week ends with a 10-question quiz you can retake.
Questions this video answers
Four weeks
10 multiple-choice questions
Starting in Week 2
Implement a single-hidden-layer neural network
Build and run a deep (many-layer) neural network
Chapters
So you're just about to reach the end of the first week of material.
On the first course in this specialization.
Let me give you a quick sense.
Of what you learned in the next few weeks as well.
As I said in the first video, this specialization comprises five courses. And right now we're in the first of these five courses which teach you the most important foundations, really the most important building blocks of deep learning. So by the end of this first course, you know how to build and.
Get to work a deep learning neural network.
So here are the details of what.
Is in this first course.
This course has four weeks of material, and you're just coming up to the.
End of the first week where you saw an introduction to deep learning.
At the end of each week, There'll.
Also be 10 multiple choice questions that you can use to double check your understanding of the material.
So when you're done watching this video, I hope you go on to take.
A look at those questions in the second week. You then learn about the basics of neural network programming. You learn the structure of what are called the forward propagation and the back.
Propagation steps of the algorithm, and how.
To implement neural networks efficiently.
Starting from the second week, you also.
Get to do a programming exercise that lets you practice the material you've just.
Learned, implement the algorithms yourself, and see it work for yourself.
I find it really satisfying when I.
Learn about an algorithm and I get.
To code it up and I see it work for myself. So I hope you enjoy that too.
Having learned the framework for neural network programming in the third week, you code.
Up a single hidden layer neural network, right?
So you learn about all the key.
Concepts needed to implement and get to work on neural network.
And then finally in week four, you.
Build a deep neural network, a neural network with many layers, and see it work for yourself. So that congratulations on finishing the videos up to this one.
I hope that you now have a.
Good high level sense of, of what's happening in deep learning.
And perhaps some of you are also starting to have some ideas of where.
You might want to apply deep learning yourself.
So I hope that after this video, you go on to take a look.
At the 10 multiple choice questions that follow this video on the course website and just use the 10 multiple choice questions to check your understanding.
And don't worry if you don't get all the answers right the first time.
You can try again and again until you get them all right. I found them useful too, to make sure that, you know, I'm understanding all the concepts and I hope they'll help you that way too.
So with that that, congrats again for getting up to here and I look.
Forward to seeing you in the week two videos.
