This is a great course, It helped me building intuitions about how neural network works, what kind of activation functions shall we use in a problem. Overall, Great content!

Really is an introduction to neural networks. Andrew is an excellent teacher, who is able to take you through deep learning easily. Very useful if you are new in this field.

It was detailed yet very comprehensive! Andrew's approach to the problem makes the concepts of deep learning, calculus, and neural network easy to understand and comprehend.

Excellent course I had already understood the programming part but getting the insight and knowledge behind it was something I always wanted to do and this course delivered.

Very interesting assignments. Got to learn python numpy & how effectively to build a neural network. Also the back-propagation implementation demonstrated was quite helpful.

You will learn to implement neural networks from basics in python without using any bulit-in libraries. It will train your basics of forward and especially back propagation.

This is the best course I've ever seen. Their explanations are pretty clear, Those who are interested in neural networks & deep learning I will always suggest this course...

Difficult because I have not programmed in Python. I trained in C and c++

I have done research in Neural networks in the 1980's and wanted to start applying it to healthcare.

Great course, I would've just preferred to learn a bit more about the calculus behind back propagation using sigmoid activation as I think that would've helped me out a bit.

Great course for those who are new to Deep Learning. For those who are familiar with DL, this course is an excellent way to revise the principle of how DNNs work in details.

This course really helped me understand what goes on behind the scenes in a neural network. It has also given me the ability to implement basic neural networks from scratch!

Appropriate content, very easy to follow and not get lost in the formulations. You end up with a very clear idea of both the concept and the methodology for its application.

It is great and Mr Wu is a patient teacher. I learnt a lot from this course which leads me to know about deep learning. I will try to learn more courses about deep learning.

If you have don't Machine Learning by Andrew Ng, then completing this course should be like cake walk for you...Very Interesting course, also Andrew Ng is just amazing <3 <3

谢谢吴博士

吴博士的课讲的非常的通俗易懂，我在学习了google出版的机器学习的速成课，对机器学习的理解还是很抽象，

但是在听了吴博士的课之后，对机器学习的原理有着具体的一些概念，懂得了怎么将图片进行特征化，懂得了前向传播和反向传播的方法，以及机器是如何进行学习的，吴博士的课让我对deep learning 产生了很大的兴趣，我收获良多。

祝一切安好

The Best course on Neural Net, Deep learning and it was taught clearly and intuitively. The Best course that I've ever seen. Thank you Andrew Ng sir for this great teaching.

Andrew Ng has an elegant knack of adjusting his speed and depth accordingly in his courses. His speed resonates exactly with mine and I thoroughly enjoyed doing this course.

Starting from very basics, the course provides a full hands-on experience in building deep NN.

Algorithms are made very clear and mathematical part of it is explained nicely.

It's super cool as a cours!!! The teacher began with basic and easy neural network and make it deeper through the course, and I found the exercises are always interesting !!

It was the basic discription of deep learning and neural networks. And I learnt some basic conceptions clearly. Andrew WU was a great teacher! I love these online classes .

课程讲的非常好，由浅至深，无论是之前接触过深度学习还是没有接触过的同学都会学到自己想学的知识。作业板块更是非常棒，讲述了编写程序的过程，一些数据处理的细节已经完成，只需要完成核心算法解决了很多时间，同时也可以阅读优秀代码理解思维过程。非常好！就是字幕有些问题，无论是英文还是中文字幕，都有翻译错误和音轨不同步的问题。希望能够更好的改善一下这个问题

Professor Ng does a great job of teaching about neural networks. I took his Machine Learning class and this was a natural extension on the one week spent on neural networks.

Very good intro on neural network. I had basically no significant previous knowledge and now I feel very motivated on keep learning and possibly experimenting on some ideas.

Best course I've seen yet on Deep Learning - very approachable, builds up from basic principles and really keeps the beginner state of the participant in mind along the way.

Easy to learn with step by step instructions with theory and programming knowledge. You gained great knowledge and will be able to implement DNN model from scratch yourself.
