Basics and Advances in Semi-supervised Learning

Lecturer:

Irwin King
The Chinese University of Hong Kong, Hong Kong

Current on leave to be with AT&T Labs Research, San Francisco and UC Berkeley, Berkeley

Objective:

The objective of this tutorial is to provide the audience an overview of recent developments in Semi-supervised learning. Semi-supervised learning has been used extensively in machine learning community for a variety of tasks including, but not limited to, classification, segmentation, clustering, etc. The tutorial plans to provide an introduction to the methods and approaches used and discusses about potential future developments in semi-supervised learning.

Content and Benefits:

Semi-supervised learning is an active topic in both the research and application fields of data mining. In many applications, labeled data are usually expensive to obtain and unlabeled data are widely observed. Semi-supervised learning is important in that the unlabeled data can help to improve the performance of supervised learning and thus greatly reduces the human effort in labeling data. In this tutorial, we will first introduce the fundamental assumptions in semi-supervised learning. Based on these assumptions, we will introduce other related algorithms, including self-training, co-training, EM-based methods, graph-based methods, and large-margin based methods. Furthermore, we will also introduce some applications of these algorithms. In particular, we will present a study of these semi-supervised learning algorithms in privacy preservation in social network analysis. Finally, we will review recent advances and future perspectives in semi-supervised learning.

Target Audience:

This tutorial is for practitioners and researchers in the machine learning and data mining community who would like to know more about semi-supervised learning techniques and methods so that they can be integrated into their applications and/or projects.
