Supervised learning from incomplete data via an EM approach

  title={Supervised learning from incomplete data via an EM approach},
  author={Zoubin Ghahramani and Michael I. Jordan},
Real-world learning tasks may involve high-dimensional data sets with arbitrary patterns of missing data. In this paper we present a framework based on maximum likelihood density estimation for learning from such data set.s. VVe use mixture models for the density estimates and make two distinct appeals to the ExpectationMaximization (EM) principle (Dempster et al., 1977) in deriving a learning algorithm-EM is used both for the estimation of mixture components and for coping wit.h missing dat.a… CONTINUE READING
