谢谢Andrew！这门课太精彩了！他不仅系统性地带领我们理解深度学习理论，也帮助我们在编程上不再害怕，这对我的帮助实在太大。我觉得课程组可以提供一些不错的参考资料和文档的话，那就更好了。

Honestly, The best course that covered all topics related to tuning is this course.

Thank you

Great explanations of many of the practical details that arise when optimizing neural nets.

Great Content and a great constructor, can't wait to complete the rest of the specilization.

Really help on systematic view on optimization and tunning the deep neural network algorithm

Excellent course that supplies not only the basics but the intuition behind the applications

Such an amazing teacher to learn from and an amazing course with a lot of helpful resources!

Very good teaching. Would be great if the Tensorflow homeworks could upgrade to Tensorflow 2

Awesome and in-depth knowledge by Andrew. I bet he is an awesome mentor. Thank you Andrew :)

Introducing some deeper knowledge about the DL framework, like hyperparameter tuning and BN.

Excellent course. For understanding the essential concepts of tuning a deep learning project

Very good information on the different optimizers and strategies for hyper-parameter tuning.

Really helpful to get a general idea of how to tune the hyperparameter! Very clear teaching!

This course was just very great, I found my self very excited to learn. Thanks Sir Andrew Ng

Definitely 5 star ..This teaching is cake walk for newbies and concepts explained very well.

The teacher is awesome and if you are interested in that topic, this course is just perfect.

Got a much better understanding of the hyperparameters! Great job on explaining the details.

Gained knowledge on various techniques of hyper parameter tuning. Good intro to Tensor Flow.

Course is good for a beginner goes from basics to advanced with practice assignments as well

i am galde to finish this course and i am very interested to continue to complet all courses

Very good course! Optimization helps a lot. And there is no error in grading in this course.

Great course for building intuition about one of the most essential skills in deep learning.

Excellent refinement of the neural net basics presented in Course 1. Very effective course.

This is a very useful course for anyone interested in improving its deep learning skill set.

Overall good!If could add dropout ,L2 homework support for tensor flow ,that would be better
