课程概述

In the fifth course of the Deep Learning Specialization, you will become familiar with sequence models and their exciting applications such as speech recognition, music synthesis, chatbots, machine translation, natural language processing (NLP), and more. By the end, you will be able to build and train Recurrent Neural Networks (RNNs) and commonly-used variants such as GRUs and LSTMs; apply RNNs to Character-level Language Modeling; gain experience with natural language processing and Word Embeddings; and use HuggingFace tokenizers and transformer models to solve different NLP tasks such as NER and Question Answering. The Deep Learning Specialization is a foundational program that will help you understand the capabilities, challenges, and consequences of deep learning and prepare you to participate in the development of leading-edge AI technology. It provides a pathway for you to take the definitive step in the world of AI by helping you gain the knowledge and skills to level up your career....

The course is very good and has taught me the all the important concepts required to build a sequence model. The assignments are also very neatly and precisely designed for the real world application.

This one went a little fast for me, can't say that I'm confident on the shapes of tensors going through RNNs and why

I was really happy because I could learn deep learning from Andrew Ng.

The lectures were fantastic and amazing.

I was able to catch really important concepts of sequence models.

Thanks a lot!

Some coding assignments were too hard to follow what was required.

Assignments were extremely didactic; there was no room for creativity. They were not transparent and gave a minimal idea of how to implement these things properly. Course moderators did not bother to answer any of my queries, making the course even less intellectually stimulating. The lectures were monotonous, and hence, I was having trouble finding them to be very engaging. Although, the professor did give some insightful points.

In conclusion, I wouldn't recommend this course to someone unless they are extremely novice programmers. Yet, one may refer to the videos to gain some conceptual clarity on specific topics.

This course felt rushed. Especially, the programming assignments, which had many errors and were frustrating at time. It is still worth it since the content is really good -- only if you are willing to go through the frustration during the programming exercises.

This course has many inconsistencies and errors in the homework. Seems like a rushed job.

some optional exercises are wrong, wasted a lot of time on LSTM backward propagation

It was difficult to follow the programming exercises because many of it had already been written. I think it would be more useful to learn one framework instead of using both keras and tensorflow in one course. I still don't know how to debug any of these frameworks. Without the forums, it would be very difficult to pass the assignments. Sometimes there were bugs in the jupyter notebook, sometimes typos that were misleading. As a result, it took me many hours stuck on one assignment. It would be good if these comments are taken into account for the future classes of this course. I really enjoy Andrew Ng.'s courses but I was disappointed at this last course's assignments.

Wonderful end to this Deep Learning Specialization. The programming assignments cover up a variety of hot topics in the Deep Learning market. The videos are very well made and teach the content in depth. A special thanks to Prof. Andrew for yet another amazing course in this wonderful specialization!

Great module, I am lucky to have used this resources in learning sequence models, I can imagine running LSTM using one of the frameworks without ever implementing it myself, Andrew Ng/Deeplearning.ai is the best!

Professor Andrew is really knowledgeable. I learn a lot from his lecture videos.

Very good course which gives a nice intuition to sequence deep learning modelling. Unfortunately, this is the weakest one among the whole specialization. There are no deep explanation of LSTM as well as GRU and back-propagation algorithm. Seq2seq models explanation is not clear and looks too inconsistent. I had to read a lot of the additional materials and blogs in order to understood a theory behind lectures. Hence, the first week assignments were disagreeably difficult to complete, whereas second and third week assignments were comparatively easy. I think this course should be revised or prolonged for 4 weeks to cover LSTM models more profoundly. Nevertheless, I would like to thank Prof. Andrew Ng for really great job and initiatives in such an important area of study!

Little bit math heavy. It was sometimes hard to understand the intuition, e.g. RNN, LSTM, GRU

I have no idea how we're supposed to walk out of these courses with the knowledge of how to build a neural network. The practice exercises are a joke. It's a bunch of functions taken out of context, with "instructions" on how to complete each. I don't understand how to do any of it, and I passed all the quizzes.

This specialization gets good reviews because people love Andrew, and although I'm sure he's a great guy, these courses provide no real practical information on how to build neural networks from scratch. I don't even know where to begin, and at this point I'm just copying solutions from the internet to complete the projects so I can just get my completion certificate.

I only recommend taking this from a theoretical perspective. If you're looking to get started with deep learning from a practical standpoint, look elsewhere. This isn't worth it.

I will remember this course for all bad reasons. Poorly written programming assignments. These things not only wasted the time but days in doing the nonsense. It must be understood that people who are enrolled in such courses and specializations are doing it in their part-time and wasting their time in solving someone else's crap is totally not acceptable. I will never recommend this specialization to anyone. It is a waste of resources (time, money and energy).

Poor submission system. Failed many times to upload and had to redo the assignments. I was using a 250Mbps high speed network. Also course materials are problematic. The instructors are not willing to fix the problems for many years.

The unit tests in the programming assignments are poorly implemented. They will fail you if your code is not exactly as expected, even when it runs and returns the correct output.

TensorFlow and Keras basics are not covered. The course states no pre-requisites as well. This was really disappointing.

What to say after spending this whole weeks in the digital company of Andrew? :) Well, I have to words but to thank Andrew and the team for making the effort and putting all this together and pulling it off the way they did! I did already the NLP Specialization of DeepLearning.AI and wanted to learn more about the inner workings of neural nets and I was not a single minute disappointed by my decision! Extremely well done overall! In particular the course on Sequence models is very enjoyable and will give you all the tools and intuition necessary to understand the background and the basis of such models and how they work! You even have a last week on Attention-based models, which is a little bit introductory, given that Attention as a concept exploded after this course was developed. Nevertheless, it is very well executed! My only critique is that, the whole specialization was developed before TensorFlow 2.0, and later on it the assignments were ported and Keras is used. But during the lectures on will not find any introduction to Keras and all this content is left for the assignments. This requires from the student more effort to understand and use Keras. What can be a bit frustrating, because Keras API also evolved during this time. I would suggest adding a couple of videos or ungraded labs in order to teach the student a bit better how to use the framework. But well, this is a minor issue. 5 Stars are for the overall amazing presentation of what is indeed important, the Deep Learning fundamentals. Moreover, Andrews last video is just very much aspiring and a powerful message that everyone in the field should come in contact with! Congrats! I hope the team plan to execute soon an updated version of the specialization in order to incorporate the new advances and to adapt it to the newest DL Framework. Apart from that the theory videos are 5 out of 5. Clear recommendation!
