Overview
Class Central Tips
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.
Syllabus
Week 1: Prediction, Errors, and Cross Validation
-This week will cover prediction, relative importance of steps, errors, and cross validation.
Week 2: The Caret Package
-This week will introduce the caret package, tools for creating features and preprocessing.
Week 3: Predicting with trees, Random Forests, & Model Based Predictions
-This week we introduce a number of machine learning algorithms you can use to complete your course project.
Week 4: Regularized Regression and Combining Predictors
-This week, we will cover regularized regression and combining predictors.
-This week will cover prediction, relative importance of steps, errors, and cross validation.

This course sucks. This is about machine learning. not about students learning. students don't learn anything with this course. apart from typing a one-liner code and pressing return.
This was supposed to be the last course of their data analytics specialization program. There is very little mathematical explanations, proofs, and the whole thing lacks a lot of rigour.
Worse, the data in the final data assignment has a lot of flaws, the provided testing data was actually (almost) a subset of the training data. Some people also figured out there were mistakes in the pro…

completed this course, spending 5 hours a week on it and found the course difficulty to be medium.
The name says everything, is just practical, none of the topics is treated in deep. And assumes that you have made almost all the other courses in the specialization.
There is a pronounced down in the quality of the weeks, the week 1 is good enough, and the week 4 just sucks. And the professors seems being hurried up in the videos.
However, can help as a very short introduction to a more in deep course.

This is good introduction to ML. The course demonstrate the practical application of ML, but due to short duration, it does not explain concepts in depth and it does glance over more complex parameters.
If you like to learn how to programme ML in R, have good experience with statistics and programming, and are happy with doing additional studies, I would recommend this course. For more in-depth knowledge I recommend Andrew Ng courese.

This is the second-to-last course in the Data Science specialization from Johns Hopkins, and the final of three courses covering actual data analysis techniques (preceded by Statistical Inference and Regression Models).
This was one of the better courses in the series, and I thought it lived up to it's name. This was certainly a practical overview of machine learning techniques. There was very little discussion of the algorithms behind these techniques, certainly much less than even in Andrew Ng's Coursera course, which is itself supposedly fairly watered-down compared to many…

Of all the JHU Data Science specialization courses I've had, this was by far the most enjoyable. I really liked how the class was more in the style of 'here's some techniques, now do whatever you want on the project.' Prior courses are, and understandably so, more constrained in the assignments. It's not until here that the student really has the tools to be able to flex their analytical muscles, and it pays off.
Also, of the three instructors, I am most favorable to Jeff Leek, who teaches this class. He communicates much clearer than Roger Peng or Brian Caffo. I find I learn more from his content than the others.
Lastly, I will say that this class doesn't hold a torch to University of Washington's Machine Learning specialization. That's expected since this is one class and that's a whole series of classes. If you're hungry for more after this one, I highly recommend UWash's Machine Learning specialization.

This course, and the entire specialization is very poorly constructed and taught. You don't really understand the concepts behind the code you are writing, and how to go through a data science project. Its probably the worst course and specialization for data science out there!
The ONLY reason why you might want to take this is if you already know ML and statistics extremely well, and just want to brush up on your skills. The R programming course was helpful for me for this purpose because I had already used R a few years ago and only wanted a refresher. Otherwise, don't expect to learn much and you would rather get confused rather than learn anything valuable.

I found this course very valuable. It isn't realistic to expect to become an expert in machine learning in the 4-5 days you might spend on studying the materials and, if you do, you'll be disappointed. However, it is a pretty good practical introductory course for those, like me, who start off knowing nothing about the subject.
If you're not too clear what machine learning is, what problems it can solve, and what the principles and procedures involved are, you'll find out in week 1. Weeks 2 & 3 are practical - you end up being able to use powerful tools like random forests for pr…

compare to some other course for deep learning i have taken this course really sucks.Does not give any understanding of deep network . Trainer seems to be quite dull in explaining concepts...
