One of the most common tasks performed by data scientists and data analysts are prediction and machine learning. This course will cover the basic components of building and applying prediction functions with an emphasis on practical applications. The course will provide basic grounding in concepts such as training and tests sets, overfitting, and error rates. The course will also introduce a range of model based and algorithmic machine learning methods including regression, classification trees, Naive Bayes, and random forests. The course will cover the complete process of building prediction functions including data collection, feature creation, algorithms, and evaluation....

recommended for all the 21st centuary students who might be intrested to play with data in future or some kind of work related to make predictions systemically must have good knowledge of this course

Issues of every stage of the construction of learning machine model, as well as issues with several different machine learning methods are well and in fine yet very understandable detail explained.

Good course for learning the basics of the caret package. However, it is not a good course for learning machine learning.

Material was very interesting but was covered at a very high level and a lot of additional learning was required.

Superfluous but the existence of the package "caret" covers the gap of other libraries like "skilearn" of python

All the formulas and code in slides are too abstract. If can be more charts to interpret that will be better.

Exercises could be more complete, and some are outdated for latest R, giving slightly different results.

A fine introduction, but there are much more engaging and better quality courses out there...

If you have taken Andrew Ng's machine learning class, it's not necessary to take this one.

I think it was a very fast course and I feel more real examples would have been useful,

Poor supporting material in a course that tries to cover a lot in a very limited time.

Overally course is good. But weekly programming assignments will be great.

Quizzes are useful exercises but need to do a lot of self studying.
