A Bayesian Criterion for Clustering Stability

International Society for Bayesian Analysis (ISBA)  The main ensemble methods discussed are Bayes model averaging, bagging, and stacking. There are 5 sections:  1) General overview 2) Neural nets, 3) Trees, 4) Ensemble method, and  5) Applications with real data. At several points in the development standard test, functions are also used to compare methods. ISBA 2012 PowerPoint Slides June 25-29, 2012  |  Kyoto, Japan  ...

Clustering Stability: Impossibility and Possibility This presentation was addressed to a specialized audience of people in Data Mining and Machine Learning. The talk provided a theory that showed how clustering stability can be used to choose the correct number of clusters, as well as demonstrate the importance of cluster stability and discussed the use of stability for clustering evaluation. Bertrand Salem Clarke (UM), Hoyt Koepke...

Clustering Impossibility and Stability This presentation was aimed at a general statistical audience and showed the importance of cluster stability (a theorem that in the limit of large dimensions can get complete noninformativity of clustering for finite sample sizes) and discussed the use of stability for clustering evaluation. Bertrand Salem Clarke (UM), Hoyt Koepke (UM and U. Washington) Department of Statistics, Florida State...
