Detecting Changes of Clustering Structures using Renormalized Maximum Likelihood Coding
So Hirai, Kenji Yamanishi (Univ. of Tokyo) IBISML2011-62
Abstract (in Japanese) (See Japanese page) 
(in English) Suppose that we sequentially observe multi-dimensional data sets, which are non-stationary. We are concerned with the issue of sequentially clustering such data sets. Specifically we are interested in how to detect changes of clustering structures. We address this issue from the view of information-theoretic model selection, which we call, dynamic model selection (DMS). Conventionally, DMS has been explored in the batch learning scenario, i.e., it is to estimate a model sequence after the whole data set is observed. In this paper we extend the DMS in a sequential manner to develop a new method for detecting changes of clustering in an on-line way. We call this method the {\it sequential DMS for clustering}. We apply it to the sequential clustering issue and demonstrate its effectiveness in comparison with other criteria such as BIC, etc.
