DemoSSL

a Matlab GUI to explore semi-supervised learning and the influence of different similarity graphs

by Matthias Hein and Ulrike von Luxburg

PURPOSE

DemoSSL: The purpose of this demo is to show how graph-based semi-supervised learning depends on the graph structure, the amount of labeled data and the regularization parameter. As algorithm we use the one proposed by Zhou et al: "Learning with local and global consistency" .


TUTORIAL

DemoSSL has been used for teaching purposes at the Machine Learning Summer School 2007 in Tuebingen, Germany. The tutorial presents the theoretical basis of the algorithm of Zhou as well as of related ones. The influences of the different parameters on the classification results of the semisupervised learning algorithm are discussed, too.
