Title
Unsupervised Learning with Non-Ignorable Missing Data.
Abstract
In this paper we explore the topic of un- supervised learning in the presence of non- ignorable missing data with an unknown missing data mechanism. We discuss sev- eral classes of missing data mechanisms for categorical data and develop learning and in- ference methods for two specic models. We present empirical results using synthetic data which show that these algorithms can recover both the unknown selection model parame- ters and the underlying data model param- eters to a high degree of accuracy. We also apply the algorithms to real data from the domain of collaborative ltering, and report initial results.
