Course 805:
Introduction to Machine Learning

(3 days)

 

Course Description

With massive amounts of data (big 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. This course starts by showing how to use machine learning (ML) as a support tool for solving business questions. It quickly moves on to provide an understanding of how ML works. Supervised models and their hyper-parameters are explored to include regression, ridge, lasso, svn, and neural networks (deep learning). Clustering of data is explored through unsupervised learning. Each section includes a complete working example showing how the ML model works. Exercises are included to allow students to explore how the model works.
