Description

This course offers you practical training in machine learning, using the R program. At the end of the course you will know how to use the most widespread machine learning techniques to make accurate predictions and get valuable insights from your data.

All the machine learning procedures are explained live, in detail, on real life data sets. So you will advance fast and be able to apply your knowledge immediately – no need for painful trial-and-error to figure out how to implement this or that technique in R. Within a short time you can have a solid expertise in machine learning.

Machine learning skills are very valuable if you intent to secure a job like data analyst, data scientist, researcher or even software engineer. So it may be the right time for you to enroll in this course and start building your machine learning competences today!

Let’s see what you are going to learn here.

First of all, we are going to discuss some essential concepts that you must absolutely know before performing machine learning. So we’ll talk about supervised and unsupervised machine learning techniques, about the distinctions between prediction and inference, about the regression and classification models and, above all, about the bias-variance trade-off, a crucial issue in machine learning.

Next we’ll learn about cross-validation. This is an all-important topic, because in machine learning we must be able to test and validate our model on independent data sets (also called first seen data). So we are going to present the advantages and disadvantages of three cross-validations approaches.

After the first two introductory sections, we will get to study the supervised machine learning techniques. We’ll start with the regression techniques, where the response variable is quantitative. And no, we are not going to stick to the classical OLS regression that you probably know already. We will study sophisticated regression techniques like stepwise regression (forward and backward), penalized regression (ridge and lasso) and partial least squares regression. And of course, we’ll demonstrate all of them in R, using actual data sets.

Afterwards we’ll go to the classification techniques, very useful when we have to predict a categorical variable. Here we’ll study the logistic regression (classical and lasso), discriminant analysis (linear and quadratic), naïve Bayes technique, K nearest neighbor, support vector machine, decision trees and neural networks.

For each technique above, the presentation is structured as follows:

* a short, easy to understand theoretical introduction (without complex mathematics)

* how to train the predictive model in R

* how to test the model to make sure that it does a good prediction job on independent data sets.

In the last sections we’ll study two unsupervised machine learning techniques: principal component analysis and cluster analysis. They are powerful data mining techniques that allow you to detect patterns in your data or variables.

For each technique, a number of practical exercises are proposed. By doing these exercises you’ll actually apply in practice what you have learned.

This course is your opportunity to become a machine learning expert in a few weeks only! With my video lectures, you will find it very easy to master the major machine learning techniques. Everything is shown live, step by step, so you can replicate any procedure at any time you need it.

So click the “Enroll” button to get instant access to your machine learning course. It will surely provide you with new priceless skills. And, who knows, it could give you a tremendous career boost in the near future.

See you inside!

I really like his teaching style. The course pace is so easy to follow. Everything is explaned very clear, and materials are sufficient for review. Thanks for creating this great course!!

The course gets you to the meat of the matter fast. Further details can be researched after you've learned the fundamentals. I believe some knowledge of statistical inference will be helpful to allow a more quicker consumption of the topics. This course can also serve as a quick revision for those with some background in ML already. In my opinion, Bogdan Anastasiei was able to structure the course in a manner that minimizes confusion (and maybe frustration) for the initiated-beginning ML learner.

This course is like a ready reckoner for revising core concepts in a short duration of time. The concepts got cleared in one go. I would recommend this course to everyone who wants a crisp and a quick walk through of all the essentials in Machine Learning. Thank you Sir for creating this course!

I really like the approach where Mr. Bogdan explains the syntex as well as output. He makes it easier to comprehend the complex output as well how to tune the syntex. Eagerly looking for his promised course in deep learning and neural networks

This course provides a great balance between theory and its application in R for supervised and unsupervised machine learning techniques.

前田19 June 2018

This is a very informative course with clear explanation. If you want practical knowledge regarding machine learning with R. This is what you want.

The explanations are clear, and the course covers most of the main machine learning methods. The instructor is methodist and engaging. Looking forward for a complete "Neural Network" course. Keep up the good work.

Roberto19 January 2018

I had good experience with R but I still learned a lot on how to run a multitude of analyses with R. It's simple to understand and very practical in the use of R. My main struggle is that only in the last lecture it shows were to find the data for the lectures/exercise, it took me a while to figure it out. After that I was able to watch a lecture and at the same time practice with the same data frame but I didn't for the beginning of the course. The other limit is that there is almost no theoretical explanation on how to make a certain analysis and how to evaluate a model. If you already know the theory behind the material and only need to learn how to do these things in R, this is the class for you.

I am fan the instructor for his approach which is theoretical and practical. Since i have all his courses on R, It is easy for me to understand and implement while watching the course. Buy it for real time execution of the ML models. Thank you

The course is very well structured. The course instructor is very clear in explaining the terms. This course is for those who would like to have a quick overview of Machine Learning techniques through R programming. I would strongly recommend this course. Also, I have enrolled myself in other courses of Prof. Anastasiei. Thank you very much Professor.

I could learn many new facts about machine learning which would be useful for me in my day to day job life. However i think few techniques like lasso, regularisation could have been explained better and bit more detailed. I hope XGBOOST ML will be added to course contents in future. On overall, i am satisfied with the course.

Very good explanation, i ve already the knowledge but Bodgan explanation makes it clear. Hope he'll do other course in machine learning but with "deeper" technics.
