Machine Learning 201
Organizer: Doug Chang
Instructors: Dr. Michael Bowles & Dr. Patricia Hoffman
Overview of the Course
Machine Learning 201 and 202 cover topics in greater depth than 101 and 102. Participants in the class should come away able to read the current literature and apply what they read to their own work. Machine Learning 201 and 202 can be taken in any order.
Machine Learning 201 begins with ordinary least squares regression and extends this basic tool in a number of directions. We'll consider various regularization approaches. We'll introduce logistic regression and we'll learn how to code categorical inputs and outputs. We'll look at feature space expansions. These will lead naturally to generalizations of linear regression, known as the "generalized linear model" and the "generalized additive model".

Prerequisites
Machine Learning 201 and 202 employ beginnerlevel probability, calculus and linear algebra (e.g. preruse the appendices in "Introduction to Data Mining" by Tan et. al. or Linear Algebra, and Probability Theory.) If you have taken Machine Learning 101 and 102 classes, you are well prepared for this course, but those are not required to start 201.
Participants should be familiar with R or be willing to pick R up outside of class. We will hand out Rcode for most of our examples, but we won't spend time in 201 going through introductory material on R. Come to the first class with R loaded on your computer. http://cran.rproject.org/ For your review, R are here: References for R, Reference for R Comments, More R references. To integrate R with Eclipse click here.
To get the most out of the class, participants will need to work through the homework assignments.

We will be using the following text as a reference for the 201 and 202
"The Elements of Statistical Learning  Data Mining, Inference, and Prediction" by Trevor Hastie, Robert Tibshirani, and Jerome Friedman. This is an excellent book. Virtually everyone in the field knows it and uses it as a standard reference. This book is free to look at on line. http://wwwstat.stanford.edu/~tibs/ElemStatLearn
