## Introduction to Machine Learning and Data Mining, Winter 2007

## ICS: 178

## Instructor: Max Welling

## Lecture TuTh 3.30-4.50pm PSCB220

## Discussion: W 3.00-3.50pm ICS 243

##

## Prerequisites

## ICS 6A/Mathematics 6A, Mathematics 6B, Mathematics 6C or 3A, Mathematics 2A-B, Statistics 67/Mathematics 67.

##

## Goals:

## The goal of this class is to familiarize you with various state-of-the-art machine learning techniques for classification, regression, clustering and dimensionality reduction.

You will implement a number of algorithms on the netflix problem, participate in group discussions and give presentations.

At the end of the class you will be able to apply these techniques to novel problems in academia and industry.

##

## Homework : Please see the slides.

## Projects: Netflix problem. Netflix site

## Code: Here is code to download the netflix data into memory (about 1Gig RAM required). Some note by Jeff Taggert
