Machine learning is the science of getting computers to act without being explicitly programmed. In the past decade, machine learning has given us self-driving cars, practical speech recognition, effective web search, and a vastly improved understanding of the human genome. Machine learning is so pervasive today that you probably use it dozens of times a day without knowing it. Many researchers also think it is the best way to make progress towards human-level AI. In this class, you will learn about the most effective machine learning techniques, and gain practice implementing them and getting them to work for yourself. More importantly, you'll learn about not only the theoretical underpinnings of learning, but also gain the practical know-how needed to quickly and powerfully apply these techniques to new problems. Finally, you'll learn about some of Silicon Valley's best practices in innovation as it pertains to machine learning and AI.

This course provides a broad introduction to machine learning, datamining, and statistical pattern recognition. Topics include: (i) Supervised learning (parametric/non-parametric algorithms, support vector machines, kernels, neural networks). (ii) Unsupervised learning (clustering, dimensionality reduction, recommender systems, deep learning). (iii) Best practices in machine learning (bias/variance theory; innovation process in machine learning and AI). The course will also draw from numerous case studies and applications, so that you'll also learn how to apply learning algorithms to building smart robots (perception, control), text understanding (web search, anti-spam), computer vision, medical informatics, audio, database mining, and other areas.

Machine Learning is one of the first programming MOOCs Coursera put online by Coursera founder and Stanford Professor Andrew Ng. Although Machine learning has run several times since its first offering and it doesn’t seem to have been changed or updated much since then, it holds up quite well. This course assumes that you have basic programming skills. Assignments also require many vector and matrix operations and slides include some long formulas expressed in summation notation so it is recommended to have some familiarity with linear algebra. You don't need to know calculus or statistics to …

Background elements:

I'm an engineer by trade and have been working on statiscal projects in field of transport regulation for about ten years.

I have some general background in maths and theorical computer science, I'm capable of programming.

I followed this course in order to developp my professional skills.

I did perform most review test without much trouble, I didn't do most of the programming exercise due to everyday work and as I wasn't too eager to get into another programming language at the time (Octave).

I had significa…

This is possibly the most outstanding university class you will ever take. It is definitely the best university level course I have ever taken, and I have taken quite a few, both in person and online (MOOC). If you have any interest whatsoever in how computers learn to recognize faces, text, or recommend movies you might like, this class is nearly perfect in every way.

The instructor is an amazing human being and as cofounder of Coursera cares deeply about education. Yes, you will have to do some programming, but the instructor assumes no previous knowledge and all the information…

I was able to finish this 11-week MOOC in ten days because the materials are a fine balance between succinct and comprehensive and very engagingly presented. I was initially turned off by the use of MATLAB/Octave as the programming language of choice for the assignments, but I found them relatively painless and well-crafted to give the student a modular view of how these machine learning algorithms work and the possible optimizations when implementing them.

I had exposure to many of the concepts before taking the class, but had never implemented or understood the mathematics behin…

Andrew Ng is a clear and charismatic lecturer, he covers advanced techniques, and he provides a number of practical tips, but the programming exercises are a bit canned, and may not fully prepare students to write their own scripts in Octave.

The exercises involve mostly copying and pasting, rather than writing entire scripts. There's a reason for this: the focus of the course is on algorithms, not on other parts of solving machine learning problems

My final concern is that Machine Learning seems to have gone on autopilot at this point, with little or no attention from Ng or anyone else who helped him prepare the course materials. Questions in the discussion forum are answered instead by "Community TA's", that is, volunteers who took earlier sessions of the course.

Despite these concerns, I still heartily recommend Machine Learning as a valuable starting point for anyone interested in data science.

This course is famous. It’s taught by the equally famous Coursera co-founder and ML-star, Andrew Ng. Though I found this class to be one of the worst learning experiences I’ve had with a MOOC, I really have to say I love Andrew’s ability to explain things and the way he teaches in general.

There were several problems, though. First of all, the set-up instructions for Mac were broken. Much more importantly, the class is not comparable to Andrew’s actual ML class at Stanford. Throughout the course, he keeps telling students not to worry about the math, and spoon feeding equations to…

Professor Ng is extremely clear. His lectures are extraordinarily well-organized, thoughtful, and clear. The assignments are interesting, relevant, and not too difficult.

After completing the course, I took MIT's open Linear Algebra course, and at that point was able to get more of the mathematical background. Professor Ng was very careful to present the material without much math -- impressive to say the least. However, once I got more of the mathematical background, I felt much more solid in my understanding.

Prof Ng simplifies ML as much as possible - and no more. In the complex arena of ML, that still leaves things fairly complex... But thanks to this course (which I'm 90% of the way through) I feel like I'll have a sufficient intuitive grasp of ML for vaguely sensible use of the many prebuilt libraries now available in the field.

This course should also provide a framework for coping with the remaining complexity entailed by deeper study, and motivation to brush up on the related mathematical tools, where necessary.

On the downside, there are some avoidable glitches in …

My opinion is very personal.

In my view, taking a class rather then reading a book has one fundamental aim: make it easier and faster to get workable knowledge on a topic and to capitalize on it.

In other word the objective of such a class should be: get knowledge you can use in a fast and effective way. This class does none of that. Really, it DOES NOT! I have maybe spent 150 hours on this class hoping to get something real out of it. All I got is confusion and a better idea about the topic in general. After 150 hours you should be able to confortably produce somethi…

Having completed a number of MOOCs I was pleasantly surprised to find out how good this one is. The course is taught well with lectures that are challenging at first glance but explained well, I felt like I made good progress in understanding the subject.

The course did require some understanding of calculus and algebra, but nothing too difficult. Some people who had not done either subject for some time did need to spend some time refreshing their knowledge. In addition, you will need some familiarity of programming or at least the willingness to put in the time required to br…

Low production values; terrible audio quality; a very traditional, mostly non-interactive approach... and yet, this course manages to be one of the best I've ever taken. The quality of Andrew Ng's teaching is just *that* good. He's a rare case of a world-level expert that's also extremely good at communicating his knowledge. This guy makes you wish you could shake his hand and buy him a beer at the end of each lesson.

This course proves that a skilled human with a whiteboard can still beat the bells and whistles of more expensively produced trainings. If you know little or nothing about Machine Learning, it will give you a solid foundation.

A lot of participants were concerned that it was a watered down version of Stanford’s CS229. And, in fact, the course was more limited in scope and more applied than the official Stanford class. However, I found this to be a strength. Because I was already familiar with most of the methods in the beginning (linear and multiple regression, logistic regression), I could focus more on the machine learning perspective that the class brought to these methods. Programming exercises were done in Octave, an open source Matlab-like programming environment.

It is a very good course for anyone who wants to begin their journey into Machine Learning. The course is well structured and well taught by the Prof. Ng.

You don't have to have any background in Matlab/Octave but a programming background is needed.

Neural Network related programming assignments are a bit hard compared to other assignments. But, overall there isn't much programming to do except for filling code in some functions.

Overall, it is a very good course and you will learn a lot at the end of the course.

It is a very well-balanced version of the course. Some time ago I tried watching the original Stanford video recording of this course and it was too dry with endless math derivations. On the other hand, this interactive Coursera version strikes the right balance between the theory and application. The course is very practical and you can build very useful systems just based on the material presented in the course. I've watched several similar courses, and this one is by far the best.

A fairly good overview of machine learning, with a fair amount of breadth but almost no depth. Good introduction for a non-technical audience, with only a high-school grasp of calculus and a little bit of linear algebra.

The exercises were very basic, and the programming exercises were pretty canned --- you could easily complete them without any real understanding of the material nor any programming knowledge.

Really, this course only taught you enough to be dangerous --- enough "understanding" to go around and build models, but not enough to avoid pitfalls.

A really good course with focus on basic algorithms and techniques in the field of ML. Regression, Neural networks and SVMs are some of the techniques taught by Andrew Ng. Video lectures are good and material is well explained. The course also helps in learning Octave and its basic syntax; the notion of vectorized code is introduced. Coding assignments are easy and most of the code is just ready to be filled. It is a very basic intro to ML nonetheless a well-constructed course.

I was completely new to ML but never felt lost while taking this course (completed yesterday). The programming assignments are a bit watered down in that most of the "boilerplate" is already written but you still get great insight with whatever is left for you to implement -- in particular, learning to write vectorized code is what I found immensely useful.

All other Machine Learning courses require an advanced knowledge of programming, this one is not, and I really appreciate it as I have a background in statistics but not much coding experience . Great course, highly recommend to anybody who is interested in data.

Best class I've ever taken.

Now I feel like I have a super power. The hard part now is trying to figure out what problems I'd like to swoop in and try to solve.

The introduction videos had high-quality audio. The audio quality of the videos I have seen after I payed for the course is terrible. Breath sounds are as as loud as the speech itself. The production quality of freely available instruction exceeds what I have experienced with Coursera.
