1.利用python实现了多层的standard NN。实现了cat 的识别。

2.对比了两层和多层的识别效果。

3.从单个logistic regression单元讲起，由浅入深！

但是我想利用编写好的代码在别的数据集上进行训练，如何更改数据集呢？

A great step by step learning experience, however, I would like to see a little less hand-holding to complete assignments.

The assignments in the course are well-designed. Learners can get through the course without too much specific background.

Brilliant. Deep explanations to help learners grasp the complexities of neural networks from the foundation up. Thank you.

The videos are very detailed, the homework tasks cover all the necessary steps of training neural nets. Loved this course!

Awesome course. Videos, Notes and Assignments really solves the purpose. Looking forward to do more courses from the team.

Great insight into the topic. Andrew is every time super-clear. I'm looking forward to see the rest of the specialization!

Thank you! Andrew, I love this course so much especially its offering easy-to-follow explanation on all important details.

a good start! very helpful to grain a overview the deeplearning algothim, know it's basic idea, and how it doing wthe real

The exams were perfect to implement the basics learned during the course. Very much like how Andrew explains the material.

Hands on instruction on this extremely powerful nascent technology is priceless. And auditing the course is free, no less!

Amazing as always. But please correct all the typos in the notebooks (especially the ones related to backward propagation)

Great introductory course to deep neural networks. Best part is the hands on excersise to code the algoriths on your own.

very deep understanding of how deep neural networks initially work were given. the problem and the solutions were clear.

This course was really good. It taught me not only the mathematics of Neural Networks but also its implementation to code

this course was amazing and I learn a lot. Andrew really teaches incredibly and understanding, I truly appreciate it.

Very good course! But I really hope the last programing assignment could be more difficult by giving fewer instructions.

Amazing course.... For a person doing my Mathematics major, I found it very interesting and learned some crucial concepts

Thank You Andrew for such valuable knowledge. Great content, great delivery ,must go through this course. I learnt a lot.

Great introductory course on Deep Learning! Maybe would be useful to include more applied use cases in the video lessons.

Great course for newcomers!, maybe more optional material for people that know calculus and lineal algebra would be great

there is no one that can teach you ML & Deep Learning better than andrew ng.

thank you very much for this excellent course

It was definite a good course and it was very challenging. Thank You for this course. Instructors are awesome. Thank You.

Amazing course, Andrew is such a great teacher. I loved the exercises in the notebooks and the mentors were very helpful.
