I really enjoyed this course, it would be awesome to see al least one training example using GPU (maybe in Google Colab since not everyone owns one) so we could train the deepest networks from scratch
Great course for kickoff into the world of CNN's. Gives a nice overview of existing architectures and certain applications of CNN's as well as giving some solid background in how they work internally.

I can't believe the number of technical problems I've had with notebooks not saving my work on homework assignments. It's very frustrating. The content is good and I will continue with the course, but this is the first Coursera course I've had (actually, the whole series in this topic) where I have experienced the lost of work - I just lost about an hour on a homework assignment.

I am very annoyed with the evaluation of the notebooks. Not with the content itself, but with the support from instructors, which is non existent.
It took me two days and 10 re-submitions to solve a problem that was unrelated to the code, but to the behavior of the grader system. No one replied my cries for help in the discussions.
Very disappointed with the lack of support.

The content of the course is very good, as with all the Andrew Ng / deeplearning.ai material. However production standards seem to have slipped for this one. Repeated sections in video material and a final notebook exercise that contained errors and required finding a work around that was posted in a discussion forum. I hope these things can be corrected for others.

I have mixed feelings about this course in particular, although one learns many interesting and useful concepts, I did little implementation on my own. Also the involvement of Keras I found annoying, yes it eases the implementation of ConvNets, but while learning I would have preferred to use tensor flow instead, or even implement a simple NumPy ConvNet on my own.
by Francesco B•
The content is very good. The exercises are a bit useless. Don' expect to be able to use tensorflow after this course. Furthermore, they teach the syntax of tensorflow 1 rather than the new 2. Therefore, when you try to solve the exercises you don't understand the discrepancies between the online documentations and what they want for these exercises

Excellent course! I have learned the skills to combine image processing with machine learning.
However, the assignment of the Week 3 has a problem that you have not fixed for a long time, and thus it wasted some time. And the assignment in Week 4 has problems of submitting, and that's why I only rated three stars. Hope you can fix the problems soon.

First, there should be an upgrade to TF 2.0. In at least one instance the documentation for a function was non-existent. Second there are many places the videos can be cleaned up eg. transcriptions are just wrong like a machine did it, or the speaker repeats the same thing twice in rapid succession. Overall the course felt unpolished and dated.

The Face_recognition assignment was a tough one to solve, i only got grader problems but still i wasnt able to figure out how to pass grader even though my code yieded right answers. That's my only complaint otherwise the videos from Andrew were really easy to understand and the programming assignments were very well documented. Thanks :)
by Chris M•
The assignments are less copy paste and some allow the student to explorer different NN architectures. However, most of the videos are still a waste of time. And the methods needed to complete the assignments aren't taught to the student. Instead you have to spend a lot of time searching and hoping you find the right method.

video courses were really good, but the programming assignments drove me nuts. I am a senior software developer and I am writing software for more than 10 years now. I had a really hard time understanding the Tensorflow code. I think it is better to suggest a student to learn the basics of Tensorflow before doing this course

This course is well organized with CNN knowledge. However, it seems like the team is overwhelmed to maintain both a big Tensoflow tech stack in programming assignments while keeping academic science core concepts. Some code comments are outdated and the mentors definitely can not follow up all the issues raised by students.

Couple of suggestions: 1) fix the artwork via neural networks assignment as there is a bug in your code 2) With the lectures I would suggest that you do a summary explanation of how the whole process works (all steps and motivation - a review) at the end of each group of lectures (one for artwork one for face recognition)
by Quoc B D•
The theory is very good but the exercise part is not good enough for me (For example in the Face Recognition exercise, I'd like to build (even a simple model) and train the triplet loss function... However, all that I can do is only loaded a trained model and then apply some simple similarity measure on encoding vector)
by Zach L•
videos are excellent and insightful as always. I thought the homework assignments for this section were the worst yet. simultaneously holding your hand so much you don’t do or learn anything meaningful, and also providing you with obscure or insufficient guidance in the moments when you’re asked to fill in the blanks.
by Ernesto G d l P•
There is major room for improvement on the automatic grader, under some particular cases, the answers are correct but the grader will give you zero with no feedback (in my case, I made a mistake with declaring local variables as global in the code). This issue is quite frustrating, the forums helped a lot though.

Great class and amazing assignments. I really enjoyed learning about CNNs, YOLO, and Neural Style Transfer.
Errors with submitting the assignments, particularly weeks 2 & 4 took away considerably from the overall satisfaction with the course.
Thank you once again for providing a rich learning environment. :)

Programming assignments were not to the level of the prior courses in the series. Should have more illustration of using Keras/Tensorflow. Assignments either were too spoon fed or there was too little reference information whereas prior courses had a good balance. Many of the keras links are dead.
by Luis F A•
Theoretical content was very informative and high quality. However, some problems with the programming assigments were annoying. For instance, for the last programming assigment some weights would not load and it was necessary to go get the weights from the github repository of some other person.

The week 1 and 2 were perfect, then week3,4 had some issues with the lectures- Andrew sir was repeating some parts and the problems/corrections in the slides.Also the week3 object detection was tough n the hints were not enough, with the errors in the assignment submission costing me a day
by Achille H•
Great content, veerything is clear and concise. Only downside is the grading of the exercises, which sometimes requires you to use a very specific syntax (even though another syntax gives the exact same results) and causes hours of painful debugging and reading through the forums.
by Cory N•
Model implementation is abstracted in many exercises. Many helper functions are created to just make things work. TensorFlow feels a little foreign still, not enough of an overview. Higher level APIs like Keras and/or PyTorch might do better here instead of mixing in TF randomly
by Cristina B•
The last two weeks sometimes bored me and sometimes I had hard time in doing the assignments. The intuition behin object detection/face recognition and neural style transfer are well explained, but some more details for understaing how these models work is missing in my opinion.
by ALEXEY P•
The lecture content is good but the programming exercises are not explained well. Quite often you are left on your own to go through Keras and TensorFlow documentation. So, don't expect much help in learning how to implement the theoretical ideas explained in lectures.
by Jaspreet S•
The course gives a high level understanding of CNN's, which is good but missing details. The content is okay. However, Andrew sounds very monotone and I happend to lose me focus very quickly in that case. Also, the many errors and corrections are confusing sometimes.
by Richard S Z•
The lectures are very good. The programming assignments are sometimes infuriating and do not add to an understanding of the subject at hand. More can be done to explain the Tensorflow and Keras code. Also complete code explained line by line would be VERY helpful.
