Why study this course

Machine Learning involves using a variety of techniques to build predictive models or extract insights from data. Our Machine Learning course builds on your basic knowledge of R and will provide you with an understanding of the machine learning process. You will learn how to:

perform cluster analysis
create regression and classification models with random forests in R

For students interested in using R scripts in Power BI, your trainer will demonstrate how we can incorporate these analyses into a Power BI workflow.

Prerequisites

You should have completed our R Programming for Data Analysis - Beginner and R Programming for Data Analysis - Intermediate courses or have basic familiarity with R
You will not be expected to code unassisted but will achieve better learning outcomes if you have a fundamental understanding of R syntax
Basic understanding of statistics (mean, median, standard deviation, variance)
