An MDL-based Change-Detection Algorithm for Piecewise Stationay Memoryless Sources with Multi-dimensional Parameter
Hiroki Kanazawa, Kenji Yamanishi (Univ. of Tokyo) IBISML2012-9
Abstract (in Japanese) (See Japanese page) 
(in English) Kleinberg has proposed an algorithm for detecting bursts from a data sequence, which has turned out to be effective in the scenario of data mining, such as topic detection, change-detection, etc. Kanazawa and Yamanishi extended Kleinberg's algorithm in an information-theoretic fashion to obtain a new class of algorithms and applied it into learning of piecewise stationary memoryless sources (PSMSs) with 1-dimensional parameter. In this paper we introduce Kanazawa and Yamanishi's change-detection algorithm, and extend their algorithm into PSMSs with multi-dimensional parameter. We prove that an upper bound on the total code-length for the proposed algorithm asymptotically matches Merhav's lower bound.
