CSE 8803ML: Machine Learning II: Advanced Topics

Spring 2012

Lecture Time

Tuesday and Thursday 1:35 -- 2:55pm in Klaus 1447 (starting Jan 10th)

Course Description

This class will cover several advanced machine learning topics, including graphical models, kernel methods, boosting, bagging, semi-supervised and active learning, and tensor approach to data analysis. The focus of the class will be graphical models and kernel methods, which are currently the major paradigms for building advanced and sophisticated machine learning models for complex real world problems.

Graphical models provide a unified view for a wide range of problems with a very large number of attributes and huge datasets, where we want to obtain a coherent global conclusion from local information. Concepts and algorithms from graphical models enable efficient inference, decision-making and learning in a variety of problems including artificial intelligence, statistics, computer systems, computer vision, natural language processing, and computational biology.

Kernel methods provide a general framework for extending algorithms designed for finding linear relations and patterns to nonlinear cases. Kernel methods approach the problem by mapping the data into a high dimensional feature space; and in that space, a variety of methods can be used to find relations and patterns in the data. Since the mapping can be quite general (eg., not necessarily linear), the relations found in this way are accordingly very general, and the type of data kernel methods can be applied to is also very general (eg., sequence data, audios, images and graph data).

This graduate-level class will provide you with a strong foundation for both applying machine learning to complex real world problems and for addressing core research topics in machine learning. Students entering the class should have a pre-existing working knowledge of probability, statistics, linear algebra and algorithms, though the class has been designed to allow students with a strong numerate background to catch up and fully participate.
