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.
