This is a good introduction to Tensorflow. Like all Coursera courses I've experienced to date, there were plusses and minuses.

The good side of each of these courses: * The courses cover the main concepts (building models, limitations, challenges, etc). They covered activation functions, Convolutions, width and depth of models, Gradient Descent and learning rate issues.

* The lessons don't oversimplify, but give you the tools you need to explore further on your own if you wish.

* Replies to my forum questions were actually surprisingly quickly answered. I was expecting the forums to be filled with months-old unanswered questions.

* Being able to replay videos was invaluable.

The less-good side:

* The exams are token, often multiple choice with unlimited retries. That is fine.

* The lessons are often replete with misspellings, grammar errors and ambiguous quiz questions.

* Sometimes, due to the stochastic nature of ML models, the errors/mispredictions differ between the Grading Rubrics and legitimately obtained results.

Would I do it again? My answer is this- I feel for six courses I have the equivalent of one junior-level semester survey course's worth of information and experience. However I was able to do it on my own time starting immediately, at my own pace, replaying the lectures at will and all for a tiny fraction of the cost and time of a college course. I do believe I have a starting point to pursue more advanced topics and for that I believe it was well worth it.

I felt the labs failed to illustrate the reasons why we were learning the concepts. They did not use examples that would have shown how the tools would have value with real projects. For example: Building Deep Learning Models with TensorFlow/ML0120EN-3.1-Reveiw-LSTM-basics only illustrated some very limited concepts. Instead of an example that had value, it was just variables and numbers. The same is true for labs_ML0120EN-3.2-Review-LSTM-LanguageModelling_with_results.ipynb. It did not actually model anything of relevance. It had a section on # Define the gradient clipping threshold, without explaining why that is important. This was true with most of the exercises. When I compare that with a course like Introduction to Deep Learning & Neural Networks with Keras the differences are vast. Keras is a simple interface and all the examples were clear and had real world applications for business. Not so with this course. A huge disappointment, and a terrible waste of time.

This is a great course and a great instructor. I also loved his course on Machine Learning with Python. My major criticism, relevant also for the course on Keras in the AI Engineering program, is that the lectures and labs are not updated to the new versions of packages. The new versions of Tensorflow, Tensorflow2.0, were changed significantly relative to the version used here. Moreover, Keras in now TensorFlow's official high-level API, which means that the code learned in these courses cannot be used for new data without implementing the new syntax of these libraries. I hope IBM will update the learning material more frequently so these wonderful courses will keep being relevant.

The instructor Saeed Aghabozorgi did an excellent job in explaining the concepts in a way everything can be understood easily. However, I still think 5 weeks is not enough for this course, given TensorFlow is more difficult to learn than PyTorch. The basics could be covered in more detail, including the tf.get_variable(), tf.gradient(), calculating gradients and other functions that were used. There could be a lecture for Linear Regression and Logistic Regression and these 2 could be moved to a separate week instead. Also, please upgrade the code to work on TensorFlow 2.1. The current code designed for TensorFlow 1.8 didn't work especially the part where datasets are to be loaded.

Four stars because some of the labs (and none of the lectures) have not been brought up to the current version of TensorFlow. There are significant differences between 1.x and 2.x, especially in the paralell processing. I don't expect a course to send me on wild goose chases across the internet having to bring their examples up to current versions. I guess you get what you pay for, no surprise that Big Blue isn't current.

A good introduction to AI networks in raw Tensorflow without heavy reliance on Keras, definitively matched my expectations!

The LSTM model and Restricted Boltzmann Machine explanations were quite hard to follow and I had to resort to other websites to learn more about the basics of these topics...

Otherwise, very interesting and I would definitively recommend it!!

Very interesting material, and easy to follow along. The notebooks are a great resource. I am glad to have been introduced to these concepts. However, I felt this course was too easy and it did not encourage the student to complete projects or any independent work. In any case, this course was worth taking.

I liked the course; however, there was no sound or transcripts for the last week of the course. This required me to research all the topics that I saw on the screen. Still a good learning experience but put more responsibility on me to learn the topics.

Building Deep Learning Models with TensorFlow Has a lot of math explanation and good visuals, but lacks training cells for the labs and there are no questions during the videos. If you want to practice Tensorflow, you´ll have to do it on your own.

Interesting course but I wish there were more opportunities to add code myself or even a proper task. I was sad not to have videos from Romeo. However, I thought that the explanations of the different deep learning models were very clear.

Quite a basic course, you don't get to learn much of tensorflow. This is an introduction to some deep learning models, the content is clear and the course it is well-structured, but it does not go very much in depth.

Excellent notebooks. I don't give 5 stars because the quality of videos could be improved and the quizzes could be made tougher. It is easy to pass the class with a superficial understanding of concepts.

Nice course to introduce you to more advanced neural network algorithms, I wish the evaluations were more challenging and based on practical exercises... there is no final assignment either.

It would have been nice if the video tutorials would explain the code section as well, and if there would have been some in-depth teaching of the code part. But this course did benefit.

Videos are good, but the code is more complex than other courses and it needs better description of what is happening, or less complicated code

Good an simple videos to understand the concept. The notebooks are very detailed and give a second layer of knowledge with practical example

Videos are good. Lab notebooks are a bit stale (still on tensorflow 2.2), so there are few wrinkles in getting them to work.

The course concepts are not in-depth enough, and the server for Jupyter notebook running is way too slow...

I expected some more explaination for the concepts. However from tensorflow website, more could be learnt.

The coding part was hard to understand. If that part could also be covered in videos as a tutorial.

Great introduction to unsupervised learning. However its an easy course with not much to offer

challenging but i wish the quiz questions were more useful in testing our understanding.

Missing more theory in the course, some labs is not working well. Need review all labs.
