Thank you very much for the excellent lectures. I am just wondering about the back propagation algorithm. When we calculate the errors backward, why do we use matrices theta instead of their inverses.
It is the best online course for any person wanna learn machine learning. Andrew sir teaches very well. His pace is very good. The insights which you will get in this course turns out to be wonderful.

This course i actually the first decent course I have taken in Machine Learning. It's really good if you have absolute no idea about what machine learning is. Don't fear the math, because Andrew (the instructor) really explains everything really good. Although a bit of programming experience is necessary, you can cover it while watching the lectures. I wanted to say the Instructor and the Mentors THANK YOU for sharing these extrordinary material with us.

I came to this course because I thought it might be a fun way to learn something about Matlab and Octave. Eleven weeks later, I'm leaving with an intense passion for studying and applying machine learning systems. Even more than that, I now have a bucket list of exciting ideas to develop as I enter my eighth decade. Thank you, Dr. Ng, for crafting such a well-balanced survey course and for making it so widely available. You are an inspiration to us.

I guess it's been a good start for me. At the beginning it was a bit challenging but after passing couple of weeks it got easier to understand. I think I have learned a lot and I am planning to do more, thanks to the Prof. Andrew Ng, who is the one of the best and most kind teachers I have ever seen. Everything he explains is pretty clear. And the motivational speeches that he made several times were really encouraging. I strongly recommend this course!

Amazing Course by an amazing professor ! I am a Mechanical Engineer, and don't have any IT / Data experience. But even then how Professor Ng laid down ML foundations and took the course forward was very smooth. I am glad I took this course and I hope that the Professor keeps coming out with more advanced videos on ML. Thank you Andrew Ng for the months of work and dedication you put in for coming out with such a brilliant course for us students !

Best online course I've ever taken so far, and it's free! Please keep it always free! ML is not my field but thanks to this wonderful course I now have a very good high-level grasp of the argument as well as some technical knowledge to start tackling real-word problems. Andrew Ng is an exceptional teacher. Assignments are a great way to commit theoretical concepts to memory. You will also learn the basics of Octave/Matlab which is useful per se.

Amazing class, great lecturer. A really good introduction and overview of machine learning concepts. It often skips the detailed mathematical background, to make it accessible for a wider audience, but I still found that enough information was given that allowed me to work out these details on my own. A lot of effort was put into creating the programming assignments, they provide a great hands-on experience with machine learning algorithms.

By far the best course you find online to learn the fundamental and math behind machine learning. Despite my hectic life and work schedule, I am grateful and so glad that I took the time to complete this course including all programming assignments and quizzes. I highly recommend this course for anybody who wants to build a strong foundation on AI science and has a sound understanding of linear algebra and some programming experience.

Although this is an introductory Machine Learning course, it covers all the important aspects and all the common algorithms, the programming skill is not so necessary with Matlab, a production-ready software, or its free software clone Octave, even if it is needed GPU acceleration. This course was much easier than I expected, even considering the lack of unnecessary mathematical theory, it was teacher Andrew Ng who made it possible.

Outstanding course. While learning to use Python or another software package to implement machine learning algorithms is critical, this course instead focuses on teaching the student to use the actual "under-the-hood" math. Using Matlab or Octave to manually implement machine learning algorithms is challenging and offers deeper insight than just calling an ML algorithm and feeding it parameters ever could. Highly recommended.

Hello this is Sparsh kaushik and i just completed my ML course offered by Stanford.
To be honest this course offered exactly what i was looking, a proper Introduction into the world of Machine Learning.I really appreciate the efforts of prof Ng for making this course and all the mentors who guided me throughout the course.
Overall this course is a must if you are new to ML and want to dive into this beautiful word of data.

This course teaches the fundamentals of Machine Learning very well. Although the use of Octave can be questioned, the exercies generally served as a good addition to the lecture videos. Aside from minor complaints like not editing mistakes from the videos in some occasions, i am very satisfied with this course! Perhaps Prof. Ng could reshoot the lecture videos to improve the video quality in the future.

Fabulous course for starters of machine learning.
Even without a solid foundation of linear algebra, calculus, statistics, one can still have a good sense of machine learning by professor Andrew's patient teaching. And the coding exercises helps me a lot in comprehending some concepts that are unclear when watching the videos.
Sincere gratitude for the teacher Andrew. Real respect.

Great Course to start with Machine Learning. All algorithms and technical expects are covered and explained in detail. Assignments are well framed and gives you a proper intuition on algorithms use and performance on real world data. Also appreciate the advise on debugging and optimizing algorithms on small test examples, before running on large data sets.

Amazing course for beginners who love challenges. Certain parts of course require lots of thinking and advanced math skills, and others are so complex that you just have to trust the teacher with it. But, in the end, you learn a very practical and useful skill that you can use to improve your and others' everyday life.

Very eye-opening for a person with a very little knowledge of the aspects and maths behind machine learning. The exercises were somewhat difficult since it's been 15 years since my last maths class and I really haven't been doing it since. So a lot of effort really needed, but once you've done it, it feels great!

I loved this course. Loved the way of teaching and how well structured it was. I can only recommend using the programming test cases when doing the exercises. I wanna thank Prof. Ng and the Tutors of this course. It has been a great experience. If I had the choice, I would purchase this course again, no doubts!

There are a lot of courses about Machine Learning, but this one is very comprehensive and it also goes deep to the theoretical base, so you do not rely on ready-made libraries, rather you have to write your own code in GNU Octave. I highly recommend this course for everyone who wants to do ML as her career.
Great comprehensive way to break into machine learning as a subject. I feel confident that this has provided the foundation I need to further explore the subject either by reading up on new topics in the machine learning area or thinking about how to apply machine learning concepts to my personal projects.
