The course was very engaging and mathematically intensive. It provides background for all the necessary tools one must know to start clustering. Great Course. Will miss this course format as 5 and 6 are cancelled!

Amazing course. The Instructors did an awesome job of preparing and presenting the material.

I think there is no better and more approachable in-depth course out there. Thank you so much!

Al inicio del curso, toda la programación es fácil, pero a medida que avanza se va complicando. Sugeriría que pusieran más notas en el código para entender las operaciones más complejas.

I really learn a lot in this course, although the materials are very difficult at first read, but Emily's explanation were clear and I would be able to get the idea after a few review.

This was another great course. I hope that the instructors indulge in a little bit more theory. Anyway it was a magnificent course. Hope the coming courses are as good as this one.

The material is complex and challenging, but the teaching procedure is carefully thought out in a way that you quickly get it, giving you a great sense of accomplishment.

A great course, well organized and delivered with detailed info and examples. The quiz and the programming assignments are good and help in applying the course attended.

Excellent course. I liked the material and the assignments are great to consolidate the learning. I really liked the recap videos to solidify even more what I learned.

Excellent course! Subjects are explained very well! Excellent quizzes that allow understanding of lectures better and excellent (challenging ) programming assignments.

Everything is clear in the course. A suggestion: for the programming assignments it would be better to write more than just 1 line of code in the proposed functions.

I really enjoyed and learned a lot from this class. It made me interested to go out and learn other machine learning methods which are derived from what was taught.

A great course to understand clustering as well as text mining. Lectures on KDD and LSH are equally important to understand and implement these algo . Many thanks

I liked it a lot. My only problem was to get the GraphLab to work here. Loved the option to download the videos and material before and the content is awesome.

Excellent Course. This course provides in depth understanding of what's going in the background when an algorithm runs and how we can tune it for our purpose.

Excellent course material and fantastic delivery. You guys made this complex learning so simple and interesting . Thanks for all this, keep the good works.

Fascinating course…

LDA is little bit difficult to understand, but K-mean and Mixture models are easy to understand and quite important for clustering..

Good presentation of topics. Detailed walk through of few advanced topics covered at the end would have been great. Felt the presentation went too fast.

A challenging course!!! It's necessary to fix some compatibility problems with Tury and Windows, because Python 2.7 it's obsolete. I really enjoy it!!!

The material covered in this course is immense and gives a deep understanding of several algorithms required to perform unsupervised learning tasks.

This is the toughest courses in the specialization so far. But if you manage to complete it, you'll have some really advance skills under your belt.

The course is really helpful, though it would be better for teacher to illustrate the concepts by using examples, instead of abstract terminologies

Excellent course. Emily and Carlos are fantastic teachers and have clearly put in a huge amount of effort in makign a great course. Thanks guys!

I​t's a really challenging course, but I didn't regret taking it since it covers many advanced concepts that could not be found in other courses.

Since I took the courses 1, 2 and 3 of this series, I really enjoyed this fourth part a lot!

Now I'm really looking forward to do some clustering!

This was probably the most challenging course of them all, I thoroughly enjoyed it! Looking forward to dimensionality reduction and the capstone.
