The "Unsupervised Learning, Recommenders, Reinforcement Learning" course on Coursera is excellent for anyone looking to deepen their understanding of these advanced machine learning topics. The course content is well-organized and covers key concepts in a clear and engaging manner. The instructors do a fantastic job of explaining complex ideas with practical examples, making the material accessible and relevant.

Very Useful Content from the basics and way to studying things is unique by choosing the real-life example and application and hands-on practice by given me the opportunity to use lab section. Every things are well drafted in lab also and lecture also. I want to say Thank you much team Coursera and Specially Andrew for give me such great opportunity for forward stepping my career. Again thank you very much ....

Thank you to the entire team on Coursera as well as deepLearning.ai for the wonderful course that was structured beautifully to help me gain knowledge of algorithmic underpinnings of machine learning as well as practically implement the many algorithms that have been covered as part of the specialization. Thank you so much for the opportunity to learn, and looking forward to the deep learning specialization!

One of the best courses I've ever done. I love how it touches on first principles, but without getting bogged down by them - I feel I've come out of it with a well-rounded understanding of and ability to implement in Python the core topics - but perhaps more importantly have been inspired by the friendly and enthusiastic (and super-clear!) delivery style to keep going and dive further in. :-)

Very good course for a strong foundational understanding of machine learning. I feel very greatful that courses like this are even available for people like me and I will definitely continue to take other courses provided by Andrew. A very comfortable and friendly person who also provides explanations in a way that makes me understand concepts I didn't think I would be able to understand.

One of the best courses I have taken. A solid theoretical foundation combined with practical work and the availability of valuable code for learning and independently developing knowledge. The immense preparation behind it is evident and highly appreciated. If you want to enter the world of ML at a high level, this is the course. A special mention goes to Prof. Ng and his collaborators.

This was an amazing first course to take. I was originally taking the original Machine Learning course when this came out. I switched and it was a very welcome change. Using Tensorflow and Python instead of Octave/Matlab was nice and getting to learn from all the advances was really cool. The interactive notebooks made learning really fun and much easier to get my hands on the material.

This course (along with the other two in the Machine Learning specialization series) is the best course to learn about Machine Learning topics like unsupervised learning, recommenders and reinforcement learning and #BreakIntoAI. Sir Andrew Ng is the best ML teacher ever and I thank him and his team for having provided me with such a great opportunity to learn. Thank You !!!!

In this beginner friendly course, Andrew taught the basic Machine Learning learning concepts in an easier to follow manner. The videos cover Mathematical intuition behind many of the basic machine learning algorithm, while the practice labs helps you to implement them. Thanks to Andrew and rest of the team for this amazing introductory course to Machine learning. Thank You...

The course covers a very broad spectrum of working of Machine Learning Algorithms with all of the mathematical concepts required to have an extensive understanding of Machine Learning Algorithm, the course is very well paced and the talent of Andrew Ng to deliver each and every idea that he has is what makes this course very well for any type of learner, Thank You Andrew Ng.

I would like to thank all the members of Coursera for designing this course, especially Dr. Andrew Ng for teaching such complex stuff with much clarity and with fun-based activities (videos and labs). I really like the tools you used for the demonstration purpose (e.g. the toys of your daughter :))

I hope to make the best use of this learning.

Thank You once again.

A sincere thanks to Andrew and all Deep learning AI crew, you guys/gals are the light of machine learning community.

I have a kid of 3, cant wait to introduce all your guys hard work to him someday in the future. Maybe (hopefully not) he is not interested in these topics, but the thing I want him to know is " how to define good people", my answer is "they share and care".

Andrew is an excellent instructor who can break down complicated concepts into pieces that are much easier to understand. I enrolled both Machine Learning course (the old version) and Machine Learning specialization (latest version) and found both of them entertaining and informative. Hopefully I will learn more about AI from courses provided by Andrew in the future!

This is a generic review for the entire specialization. Thank you so much for creating these detailed video tutorials, with almost all the required information that a newbie requires. I got a little confused with reinforcement learning and still did not get the intuition behind it, but the rest are all too good. Thank you so much again, I'm grateful for the course.

I've been previously exposed to recommender systems and reinforcement learning. However, I couldn't really understand what was going on underneath them. This course gave me the concepts and tools to understand how these algorithms actually work. Though these algorithms are a bit complex, I feel better prepared to upskill myself in using these tools. Thank you!

Good course. I learn balanced amount of theoretical and practical knowledge in Machine Learning. This course equips me extravagantly to wide range of knowledge in machine learning. However, there is no in video quizzes which I believe useful to check my knowledge before graded quizzes. Overall, I satisfied with the course and very recommend this to others.

Outstanding set of courses.

My only criticism is that it is not at all clear how/where to download the lecture slides or the files for the programming assignments for ones reference later on or how to access the discussion forums - there are absolutely no links on any of the courses' pages.

Overall, the instruction quality and content are simply superb.

With the last course of the specialization, I gained useful knowledge about machine learning techniques such as recommender systems or reinforcement learning, which are used in modern applications today. I think this specialization will be one of the best starters for those who are starting machine learning or want to improve their existing knowledge.

My interest in Machine Learning peeked after taking this course with Andrew. He is such a great teacher. He made the most difficult concepts easy to understand. I just have to keep practicing this course again once more to "reinforce' my learning. This specialization is a solid start for anyone who wants to break into Data Science and ML. Best Wishes

Andrew Ng has an amazing talent of breaking down even the most complex topic to its core components, making it clear not only how it works, but also how, when, and why to implement different algorithms. Through diagrams and coding exercises, he has helped me to understand the processes of so many machine learning algorithms, and he made it fun.

From the three courses of the Machine Learning Specialization, this one was the one most familiar to me, specially recommenders, which I've spent some time working with before. Same as the other two courses, good content and clear explanations. The support material for all the three courses are great also, something I forgot to mention before.

This Beginner Level course provided a very interesting insight to machine learning & deep learning. The flow of the course is well structured, so I found all the topics really interesting throughout the course. I'd recommend this to anyone willing to start their machine learning journey and kudos to the authors and producers of this course!

Another terrific course with Andrew Ng, who continues to explain the topics very well, as well as adding discussion of ethical issues with Machine Learning and AI, which I really appreciate & think is incredibly important for everyone in this field to understand. I'm really looking forward to the next specialization with Andrew!

This course was like a breakthrough for me. It organized my knowledge of machine learning.

I loved Andrew's insistence on learning materials deeply, digging deeper into what's happening behind each model, and engaging with the math in a really really smooth, straightforward, and lovely way.

Many thanks to Andrew and his team.

I absolutely love how lecturer Andrew Ng guided me through the concepts and algorithms of Machine Learning. The simplistic way he explained the functions and concepts really showed that he's the top, the leading expert in this field. I'd love to thank him personally for this amazing learning experience. Andrew, you rocks!!
