数据降维和聚类中的若干问题研究(英文版)

目 录内容简介
A central research area in data mining and machine learning is probabilis-tic modeling because it has a number of advantages over non-probabilistic methods. Given a probabilistic model, one could fit the model using max-imum likelihood (ML) method or Variational Bayesian (VB) method. In ML method, (1) many algorithms may converge very slowly and thus com- putationally efficient algorithms are often desirable; and (2) the choice of a suitable modelis difficult though many model selection criteria exist and thus criteria with higher accuracy are desired. In VB method, employing
different priors may yield different performances and thus studies on how to choose a suitable prior are important. In this book, three sub-topics were studied: Modeling, Estimation and Model selection for dimension reduc- ition and clustering.
