| Research Abstract |
Ranking is the problem to predict orderings or permutations over data, and it appears in many application tasks such as information retrieval, recommendation, risk analysis, bioinformatics, natural language processing, and so on. In this project, we developed efficient ranking prediction methods based on the online learning theory.Our methods predict almost as well as the best ranking in hindsight. Further, we generalize our methods to online prediction methods for some classes of combinatorial concepts.
