About the Course

In Course 2 of the Natural Language Processing Specialization, offered by, you will: a) Create a simple auto-correct algorithm using minimum edit distance and dynamic programming, b) Apply the Viterbi Algorithm for part-of-speech (POS) tagging, which is important for computational linguistics, c) Write a better auto-complete algorithm using an N-gram language model, and d) Write your own Word2Vec model that uses a neural network to compute word embeddings using a continuous bag-of-words model. Please make sure that you’re comfortable programming in Python and have a basic knowledge of machine learning, matrix multiplications, and conditional probability. 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....

A truly great course, focuses on the details you need, at a good pace, building up the foundations needed before relying more heavily on libraries an abstractions (which I assume will follow).

A neatly organized course introducing the students to basics of Processing text data, learning word embedding and most importantly on how to interpret the word embedding. Great Job!!

Good for the basics of NLP. Good mix of examples from classical NLP (e.g. n-grams) and neural nets (e.g. embeddings). As usual from, great motivating examples such as autocorrect and autocomplete to help us understand the materials. The neural net examples could do with more equations as in other courses.

Thank you for the Lecture. I enjoyed it a lot! One thing I did not like too much was reading aloud and fast complex equations. I got distracted a lot when that happened. Also the Grade of the programming assignment is very slow and some additional verification of the programming task would be helpful.

A good course overall. I wish the assignments were a bit more challenging though. Still, we have covered a lot of ground. And for those who know nothing about the word embeddings, I think this would be a perfect first course to take. So all in all, time well spent.

I found the course really helped to reinforce my understanding about importants concepts like n-grams, HMMs and word embeddings. The labs are pretty well spread out, and by the time you get to the week-ending assignments, you have all the info you need to complete.

The lectures on the Viterbi algorithm were a little wooden and there were no summary text (reading) tasks (as there often is in other courses), however this is a worthwile and informative course.

In the first and second week the exercices have some unecessery pranks in the data formatation just to make the exercice harded, but it take out the attention for what matter in the course that is NLP

Very good to see how the "from scratch" concepts are presented; nevertheless, I have the feeling that a very little "real use case" problem has been presented, with tiny sentences being analyzed.

Good course, but the lecture notes in week 2 can be much more improved. Understanding Viterbi algorithm without visuals and animations was very difficult. Apart from that, great course!

The course is exceptional in its own way by bringing people to the understanding of probabilistic models. Crisp & Clear. But one need to explore & practise more to gain expertise.

The Viterbi algorithm introduction is a bit hard for us to follow. Probably some writings may help guiding through each steps.

Esta especialización junto con la de Deep Learning se complementan y es son más claros los conceptos y prácticas, gracias!

The tutor sometimes pass the slices too swiftly. I hope that he could wait 2-3 seconds after finishing speaking.

Sone Quiz should also be there. Assignments can be solved by python knowledge an following the instruction

Assignments were incorrect.

Lot of content was squeezed in the last week. Even spread would be ideal

I didn't like weeks 1 and 2 too much but I liked week 3 and I really liked week 4.

I liked the lecture, very well prepared. Only the part on metrics was a bit short

This is a good course but I would like to see more emphasis on the mathematics.

Great course, but the last week felt a bit messy with submission evaluation.

Not sure if it is on purpose, but W4 labs have repeating content.
