Semi-supervised learning in medical image database

Abstract

This paper presents a novel graph-based algorithm for solv- ing the semi-supervised learning problem. The graph-based algorithm makes use of the recent advances in stochastic graph sampling technqiue and a modeling of the labeling consistency in semi-supervised learning. The quality of the algorithm is empirically evaluated on a synthetic clus- tering problem. The semi-supervised clustering is also applied to the problem of symptoms classification in medical image database and shows promising results.
