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.

Very good. I have no complaints. I though instruction was very clear. Assignments were very helpful and challenging enough that I learned something, but not so challenging that I got stuck too often.

The course is very interesting and it gives an insight into recurrent neural networks (RNN). The practical exercises are interesting but I found them in a bit raw state compared to the previous courses of the Deep Learning Specialization. Nevertheless I would still highly recommend to follow this course. Thanks a lot to organizers.

Everything seems logical, except the programming assignments. Although I went through week 1 programming assignments only, I often had to face some problems with insufficient information. Lecture videos are easy to understand, but not all the details are explained. (This is the point where I need to find some information by hand.)

As a non-computer science background student, the course was overwhelming, I got lost in the equations most of the time. Maybe a lower level course could be considered before starting this one. Nevertheless, this was an informative course about sequence models. Lots of quizzes and programming assignments reinforced my learning.

Videos are great; but as usual TP are too guided (hence boring) and do not use today frameworks (Pytorch, tensorflow 2). TPs should either be completely coded by candidates (only introduction + resfresh on concepts + objectives) with evaluation on final accuracy/f1 score <or> they should be no TPs at all and more MCQ tests

Content her is great - the first week covers the basic RNN models in a very clear way and the assignments are interactive and interesting, building on the explanations in lectures. One downsides is that the production quality is poor and would benefit from some re-recording to remove bloopers and make it smoother to watch.

I wish it was a bit more interesting. It also kinda feels like Andrew has a bit of a problem himself in understanding the paradigms stated in this course, and that makes me feel somewhat confused as well. Would recommend for the math, the notations are weird and confusing sometimes but it is understandable for most parts.

This is a very interesting course with good explanations, which give a brief but sufficient introduction to sequential models like GRU and LSTM. One star is dropped because the CNN course (#4) is still better than this one in terms of explanations, while course #2 is better in terms of relevant material and pace (to me).

Although I really really really love this series and although I always gave 5 stars, I think the quality of this last module is a lot less better than the previous ones. I think convolution was way more difficult but the explanation was awesome. Unfortunately, i think explanations in this module are a little sloppy.

As usual, Andrew Ng's stellar talent as an educator shines through. Unfortunately, some of the video editing is a little scrappy, and the assignments could use some more polish. Especially in areas where they catch quirks in the grader. Luckily the forum support is excellent. This course is definitely worth doing.

Overall nice course, learned a lot about NLP and Speech to text. Course is more oriented towards NLP applications, I was also hoping to learn more about time series analysis. Feel like the course could have been longer 4-5 weeks since RNN, LSTM and GRU is pretty long topic and 3 weeks seems to be too short for it.

Recomiendo ampliamente este curso, te proporciona un claro entendimiento de los modelos secuenciales y recurrentes. Es excelente, aunque a diferencia de otros cursos de esta especialización no explicaron en detalle algunos aspectos de las RNN, me hubiese gustado que profundizaran un poco más en backpropagation.

The RNN, LSTM< and GRU were very good. But the Week 3seemed a bit abstract. More could have been covered in Audio, Attention.

ALso the Jupyter Notebooks was frequently crashing, and it took lot of attempts to re-open the existing one. Lot of time wasted. Also it took long time to to submit and run the program

This course provided a nice high level overview of RNN models and associated Keras implementations. The tricks and tips given were a useful addition to my ML arsenal. The only thing that I feel discredits this course is that the programming assignments are easy to gloss over and pass without much engagement.

Great introduction to RNNs and how to implement them in keras. I suspect it is a relatively new course as there are still typos and a few errors in the assignments (otherwise I would have given 5 stars) but the forums help you to find your way around them and hopefully in future versions they will be fixed.

Excellent lectures, some part was difficult and it took time for me to imagine the content of each parameter (e.g. when we talk about X, or a, or Waa what is the size of them and what do they represent). But in the exercises, it became more understandable. Exercises need previous knowledge of Keras and OOP.

It is a fabulous course content-wise. However, I personally find the programming exercises overly easy (the instructors already build the framework for you and the only thing you need to do is to fill in the blanks), s.t. I'm still not able to build an RNN from scratch after completing all those exercises.

This course is good. It introduces the concepts regarding recurrent models. I specially like the attention model videos. In general, the exercises are well written. However, I'm not very familiar with Keras and working on the Keras code really takes my time even I'm quite experienced with Tensorflow.

Professor Ng did a good job explaining sequence model and I finally understand the basic theories. However, there is room to improve especially on the Keras library part. I hope you can add some simple tutorial for that. Also, I still don't understand how to translate the architecture to Keras code.

This is a very well structured course. I initially started this course almost 10 months ago but got distracted and started to learn sequence models on my own. But, at the end end I resorted to this course again and got my basics cleared out. Thanks to team for designing this course!

Great explanations on the videos, and well designed programming exercises. However, the complexity of the programming tasks is not well dimensioned (1h - 1:30 h may be too little). Worse, some of the exercises are not well explained, with misleading information (e.g. about model tensor dimensions).

this is a well structured course, but it is not for beginners at all, andrew ng had put alot of his efforts in this. As a computer science major, I was able to grasp the maths concepts but for anyone comming from diffrent background its far from possible to understand all the theoratical concepts.

There was not enough theory as the first three courses. Some explanations were superficial and difficult to understand. Maybe drawing the shape of the inputs, outputs, and other matrices in lectures would help to better visualize what's going on inside the networks. Overall, it was a great course.

It's a great course. The information and knowledge that you get about Sequence Models is fantastic as a primer. Andrew is an amazing teacher throughout the entire specialization altough I found the content of the videos in the Sequence Models slightly more rushed than the previous 4 courses...

The theory was absolutely interesting and an eye-opener. The programming exercises were hard to make because of the keras/tensorflow knowledge and I actually ended up just fill-in in things, as were given in the examples, without really knowing what I was doing. Time for a Tensorflow course.

Poderia dar um pouco mais de instruções na hora de usar as funções do Keras. Ficou um pouco confuso.

No assignment da semana 3 (Machine translation). Tem um output que não precisa estar exatamente igual mas o curso não fala isso e acabei gastando bastante tempo nisso, só vi depois no fórum.
