In Course 1 of the Natural Language Processing Specialization, you will: a) Perform sentiment analysis of tweets using logistic regression and then naïve Bayes, b) Use vector space models to discover relationships between words and use PCA to reduce the dimensionality of the vector space and visualize those relationships, and c) Write a simple English to French translation algorithm using pre-computed word embeddings and locality-sensitive hashing to relate words via approximate k-nearest neighbor search. By the end of this Specialization, you will have designed NLP applications that perform question-answering and sentiment analysis, created tools to translate languages and summarize text, and even built a chatbot! This Specialization is designed and taught by two experts in NLP, machine learning, and deep learning. Younes Bensouda Mourri is an Instructor of AI at Stanford University who also helped build the Deep Learning Specialization. Łukasz Kaiser is a Staff Research Scientist at Google Brain and the co-author of Tensorflow, the Tensor2Tensor and Trax libraries, and the Transformer paper....




Great Course,

Very few courses where Algorithms like Knn, Logistic Regression, Naives Baye are implemented right from Scratch . and also it gives you thorough understanding of numpy and matplot.lib



One of the best introductions to the fundamentals of NLP. It's not just deep learning, fundamentals are really important to know how things evolved over time. Literally the best NLP introduction ever.

No longer required. Beyond my present knowledge.

Content is verbose and locks context in places

by Lorena P


I believe that explanations where too shallow

v​ery good course, a lot of stat and math

So many small mistakes here and there

Problems in week 3 Assignment

Just ignore the video!

Too easy

I believe the course does not allow you to study NLP in depth. Compared to the deep learning specialisation by, this course has probably hours(!) of video material less. PCA is for instance presented in ~4 minutes and the lecturer concludes with "now that you know all about PCA". The only further reference provided is a link to the standard textbook in the field, no detailed study guide or references for individual topics. Excercises are done in notebooks and test beginner python skills instead of nlp understanding (Basically: "Look up key i in dictionary j and store vector k"). It does do a good job in giving an overview about NLP.

I was torn between two and three stars. Two, as mathematics are dealt with far to shallow. No proofs, no motivation, nothing. And in the final week, there is a massive notebooks with a lot of flaws and a lot of cells you have to code in a specific, sometime suboptimal, way. Otherwise, the grader will throw errors. All in all, things are handled to shallow and it is more of a coding lesson than a deep dive into ML, which necessarily requires mathematics. This is one more of those "Become a data scientist without mathematics" things the world does not need.

by Shawn


lectures are pretty mediocure. basically it lacks motivation behind algorithms, you are simply told what to do, really like "machine" learning

you'll spend a lot of time in the assignment, not focusing on implementing your algorithm, but adjusting incorrect input or output format that passes all tests but fail the final grading for some reason (also in week 3 the assignment has one or two questions that do not even tell you what's the input data and you have to "print" them to get an idea lol)

The lectures skip over important features that should be explained in more detail. Other important concepts are left to the labs, even if those require a good explanation. Evaluations are not a help to practice or understand concepts. Most of the time spent on evaluations is figuring out how to do things in Python rather than follow the concepts. People can obtain 100% in the evaluations but learn nothing. It is indeed a very poor course.

by Paul D


Rather shallow and elementary course, I am disappointed. I did the deep learning specialization so I expected the same quality level here, but no it's not the case. In a way you're exploiting the fame of Andrew Ng to attract students, but Andrew is not teaching here and you're offering a content that is not up to expectations. I will try the following course and hopefully it will be more interesting.

by Foteini D


The course covers some basic aspects of Natural Language Processing and can serve as an introduction to NLP, but it definitely not an in-depth course. The assignments are just some Python scripts where you have to fill in the gaps, which is not a helpful learning strategy, since you aren't given the opportunity to try things out by yourself and figure out what works.

by Darien S


There are too many errors in this course. The lecturing is uninspired. The assignments are boring and weak. Coming from many Andrew Ng courses and the Deep Learning Specialization, this is a huge disappointment. You had an opportunity to create an organization responsible for top tier tutorials and learning, and this level of commitment wastes that potential.

by Jus P


T​his particular course was not as good as other DeepLearning.AI courses are. This one was a bit non-intuitive and a lot of not so real life useful modules. Would be more interested in implementaion of applications, rather than building from scratch, because in real life implmentaion, we all are going to use libraries only.

by Fabian Z


The content is pretty nice, but the videos are so superficial. The assignments provide more theoretical background than the input sessions. There are many mistakes in the slides as well as in the assignments. I feel that this course is not mature yet.

by Krithika R


The course runs through the important NLP topics at a very high level. It mostly explains the steps to solve problems using various methods, but an intuitive explanation of the techniques is missing.

by Yu Z


The concept explanation is too weak in videos. The homework is too much focus on coding. The overall course lacks interactions between teachers and students , but I do learn some new stuff.

by Tim L


Exercises can be completed without the need to understand the methods. No flexibility in solving the programming assignments. Many small inconsistencies in the notebooks.

by Shafquat M


The course is very hurried without going into much details. It would be better if the instructors spend more time on the theory rather than skimming through codes.

by Kabakov B


Too superficial. Without DL specialization it could be too tough to understand what is takes place here. With it, everything is just too simple and flat.
