Duration 3 days – 21 hours

 

Overview

 

This training provides a practical introduction to Machine Learning (ML) using both Python and R—the two most widely used tools for data science and analytics. Participants will learn how to prepare data, train and evaluate ML models, and interpret results using structured workflows and real datasets. The course covers supervised and unsupervised learning methods, including regression, classification, clustering, and model validation techniques, with hands-on labs for both Python and R implementations.

By the end of the course, learners will be able to build end-to-end ML pipelines, compare model performance, and apply best practices in feature engineering, evaluation, and deployment readiness.
