Course 805:
Introduction to Machine Learning

(3 days)

 

Course Description

With massive amounts of data available and inexpensive computing power to quickly process the data, it is now possible to find computational solutions to problems previously too expensive and time consuming to solve. The course provides an understanding of how machine learning works. Supervised models and their hyper-parameters are explored to include regression, ridge, lasso, SVM. Clustering of data and anomaly detection are explored. Decision Trees and an introduction to Bayesian Models are included. Exercises are included to allow students to explore how the models works.
