This course I believe is one of the most vital one after the first course in the specialization! Professor Ng covers all the concepts required for you to understand and master this course.

You might have to refer to additional resources to get a complete grasp of the concept post each video.

Great and easy-to-follow introduction to improving deep neural networks. If you are already familiar with vector algebra, many things are explained quite slowly. One star left out because the content has not been polished, but there are minor errors here and there with separate corrections.

Going from the Basics of Logistic regression-Neural network -regularization- hyperparameter selection and finally knowing how Tensor flow makes it all come together is just brilliant.

I feel confident as I understand the basics well before using a framework that makes it so easy to execute.

Realy recommended for those who finished the first course and/or the machine learning with Prof Andrew Ng. A good in deep exploration of different topics in regularization. An efficient introduction to TensorFlow which will put your feet on the first step of using DeepLearning platforms.

Need some improvement! I think the course is a little bit rush, especially on the 3rd week. I really like the 'test' assignments, which helps me to clear out a lot of important concepts. But the programming assignments sometimes bothers me not in the way of programming, but in the way of

Excellent! Very practical intro to tuning and improving neural networks. The four star is because I felt the programming exercises could be harder and not so much fill in the blanks. I don't think I would be able to code a adam optimizer or momentum from scratch given an empty py file.

A great course indeed! I give 4 star only because I'd have liked more lectures and programming exercises about Tensorflow, and how to train models using GPUs. Similarly, it'd have been great if Andrew explained in detail how to implement Batch normalization using computational graphs.

Great course. Thanks for making it available.

I would have enjoyed more tensorflow lectures to help understand the underlying mechanism of the platform. I suppose the intention is to provide that understanding through the assignment, but more discussion in the lecture would be nice.

Good course but it would be interesting to add some other methodologies on learning rate ("Cyclical Learning Rates for Training Neural Networks", "Snapshot ensembles") and some explanations on categorical variables and embeddings matrix ("Entity Embeddings of Categorical Variables")

Great course giving insight on how to fine tune deep neural networks. I believe the contents need to be a bit polished but that's totally understandable given its early stage. The comments in the discussion group will for sure help to fix some typos and make this course even better.

This course helps me a lot in tuning hyperparameters in training machine learning model, just one issue is the last programming exercise when using framework the guide is missing something, which is hard for some to complete, for me, I have to use Google Search to find the solution

Need Information about other parameters like #of iterations, how to choose number of hidden layers?, number of neurons in hidden layers, inclusion of few other strategies to choose neural network model will be helpful. If they are covered in next courses, then please ignore.

Thanks

A useful class delving into the nuts and bolts of building a reliable nn. Well structured and explained. I feel like the use of Jupyter in the homework makes it simpler than it should be. A large portion of the code is already written and the instructions often give up the answer.

For a person, who know a little on deep learning, I learned lots of things or, at least, got a clearer view on many concepts. A little reproach on the notation system : question on quizz sometimes might not be very clear for me - and the flaws of the grader on the assignments.

A very good course for taking understanding of Deep learning one level above the basics. The course is theoretical, but the team has done their best to make it as much hands-on as possible.

I did face some intermittent platform issues with saving and submitting my assignments.

Helps to have a structured approach towards tuning the hyperparameters rather than randomly doing. Also the course also helps understanding why such tuning is necessary and what improvements are being made in the model. Useful course but not suitable for beginners in ML/DL.

Material is awesome like all courses professor Andrew does. But (a) programming assignments are in style 'fill a couple of lines in 90% ready code' instead of end-to-end developing with guidelines and (b) there are a lot of mistakes in subtitles, assignments and even videos

The theory was good, but I think jumping to tensorflow at the end wasn't a logical, progressive step forward. They should have solidified the concepts more thoroughly, rather than jumping to the Tensorflow API. One would really want to have Tensor flow in a separate MOOC.

A lot of content was repeated from the Machine Learning course by Andrew Ng on Coursera. Also, more on TensorFlow and other frameworks implementation would be interesting to learn. But at the end of the day, I did learn a lot of interesting aspects of deep neural networks.

Course is very good especially when revealing "secrets" of various optimization techniques. Once again programming excercise is rather easy to pass as you are guided step by step so there is no space for serious mistakes. More "open" excercises/chalenges would be desirable

This one took a little longer than usual to complete, It took more willpower to come back to it and continue in the course. It seemed harder, or explained lesser than the first course. Nevertheless, after spending extra time on it, Ive finally completed it. Thanks Andrew!

Parameters tuning is ok to follow, it would be easier if you have numerical methods basics. But Tensorflow is not easy to deal with. Maybe it need a separated course. I will get through to programming assignment again to understand it clearly with tensorflow manual pages.

The second class on machine learning is still very informative. However, it's very hands-on and teaches me mainly how to tune learning algorithms to run faster. Hence, it's not very intellectually stimulating. Nonetheless, this is still a very educational course overall!.

The course is great. Andrew is one of the best tutors one could get.

The only reason I rate it with 4 stars is that the TF assignment is not updated to TF2. TF 2.0 with Keras really is a state-of-the-art framework and imho there is not much value in learning TF1 anymore.

Great sequel to Neural Networks and Deep Learning. Relatively short course and the most relevant topics in Deep Learning are reviewed. You also practice with TensorFlow, a well-establish Neural Network programming framework that is widely used in academia and industry.
