Overview

Machine Learning is the basis for the most exciting careers in data analysis today. You’ll learn the models and methods and apply them to real world situations ranging from identifying trending news topics, to building recommendation engines, ranking sports teams and plotting the path of movie zombies.

Major perspectives covered include:

  • probabilistic versus non-probabilistic modeling
  • supervised versus unsupervised learning

Topics include: classification and regression, clustering methods, sequential models, matrix factorization, topic modeling and model selection.

Methods include: linear and logistic regression, support vector machines, tree classifiers, boosting, maximum likelihood and MAP inference, EM algorithm, hidden Markov models, Kalman filters, k-means, Gaussian mixture models, among others.

In the first half of the course we will cover supervised learning techniques for regression and classification. In this framework, we possess an output or response that we wish to predict based on a set of inputs. We will discuss several fundamental methods for performing this task and algorithms for their optimization. Our approach will be more practically motivated, meaning we will fully develop a mathematical understanding of the respective algorithms, but we will only briefly touch on abstract learning theory.

In the second half of the course we shift to unsupervised learning techniques. In these problems the end goal less clear-cut than predicting an output based on a corresponding input. We will cover three fundamental problems of unsupervised learning: data clustering, matrix factorization, and sequential models for order-dependent data. Some applications of these models include object recommendation and topic modeling.

Following are the problems with the course:

- No diagrams

- No examples

- No clarity if a particular variable is a scalar, vector or matrix

- Professor simply reads from the slides and does not add much to what forms part of the slide deck.

- No formative assessments (the only quizzes that we take are high pressure do or die quizzes)

- Many trick questions in the quizzes (for example: " Which of the following are NOT active learning strategies?")

- Ambiguous language ("This question tests a fundamental…

There are not many courses online that provide such in-depth learning experience in Machine Learning. This course goes into some details and mathematics of the algorithms being used. It demands a good amount of time every week to understand and apply all that is being taught but that is what makes it good. It is not like many other courses that you can take and pass with minimal effort but at the end of it, it is worth spending time taking this course.

A great introduction to machine learning for those who are well grounded in the mathematics of undergraduate level. It explains the algorithm and the mathematical background of various machine learning techniques very clearly.

Only one point I did not like about this course was that the assignments were not well organized. I hope it will be improved in the future.

Some weeks are better than others. In general, too much emphasis on algebra, and not enough on geometric interpretation of algebra and solutions. I found myself cruising the web for better explanations.

In this respect, the class I am listening to right now, the class on support vector methods is pretty bad.

I am not taking class for certification, but I have looked at the quizzes and I agree they are not good.

Questions are about little finicky points of the subject matter, and not much else. The course is pretty worthless without some coding with explanations, and there is not much of that here.

I am going to go to Ng next even if he does not use python to implement.

Beautiful course which covers advanced concepts of machine learning. Professor Paisley covers a whole range of topics and breaks down hard concepts clearly. This course is very theoretical. There are four programming assignments which give an opportunity implement some of the algorithms learned. The only downside is that weekly assignments lack mathematical/programming rigor which can be improved in future sessions. Overall must do course for anyone interested in this topic.

This course requires a solid foundation on probabilities, calculus, linear algebra and programming. Provided these prerequisites are available (anyone who is serious about the field should possess these skills anyway), the course will become an incredibly useful resource to break into Machine Learning. The only downside I found is that neural networks is not covered. A great deal of the current breakthroughs in ML are happening in this area!

Amazing in-depth knowledge. Almost all algorithms out there are being explained.

But:

Terrible execution, lecturer is just reading the slides and explaining a bit. Not enough real life examples or any code examples. No interactivity. Reading a book on ML would help more.

No good examples. No practices. Assignments are a bit off.

The content of course is very good. Mathematical concepts covered are up to mark. Quiz and Assignments gives good insight about ML.
