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....




excellent course. Be prepared to learn a lot if you work hard and don't give up if you think it is hard, just continue thinking, and interact with other students and tutors + Google and Stackoverflow!



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

The class is good but it is too simple. I expected the professor will provide more detail about the models. This is just an introduction and weak for a specialization.

創建者 Brian F


There was some good material in here, but it was rushed and is deserving of a much longer course - especially compared to some of the other modules in this course.

創建者 Chuxing C


the lack of assisted practices made it harder to digest the contents and methodologies.

strongly suggest to develop some practice problems with explanations.

創建者 Michalis F


Good in introducing caret package and getting some experience in running algorithms. Was expecting more in-depth discussion about the methods though.

創建者 Davin G


It's an excellent crash course to machine learning but the stats part was rushed. Had to look up external resources to understand what was going on.

創建者 Léa F


Rather good overview. The contents could dig deeper into each subject, and it would improve the course a lot if some exercises in Swirl were added.

創建者 Miguel J d S P


I didn't enjoy the supporting materials and the quizzes weren't very interesting. The final project was fine.

The subject is super interesting.

創建者 Max M


Should have gone into more depth and included swirl lessons, like previous courses. The quizzes were very challenging though, so that helped.

創建者 Kyle H


A brisk introduction to some of the basics of Machine Learning. Will leave with an understanding of a few ways to use the caret package.

創建者 Manuel E


Good course, but either explanations are too fast paced for the level of difficulty, or my neurons have began to decay with age.

創建者 Noelia O F


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

創建者 Joseph I


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

創建者 José A G R


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



Instructor rushes the course and does not explain much in the same level of details as respective quiz requires

創建者 Hongzhi Z


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

創建者 Henrique C A


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

創建者 Alex F


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

創建者 Yingnan X


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

創建者 yohan A H


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

創建者 fabio a a l l


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

創建者 Rafael S


this course seemed too rushed for me, too little content for such a extense subject

創建者 Raj V J


more needs to be taught in class. what is taught is not sufficient for quizzes.

創建者 Surjya N P


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

創建者 王也


Too different for beginners but not deep enough for ones already know R.

創建者 James F


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