Abstract
Recently, many applications tend to find common and distinctive features from a group of datasets, of which distributions and structures are generally various. However, most existing methods can just cope with specific problems with fixed distributions and structures. In this paper, a more flexible framework for multi-block data learning is proposed. There are mainly two advantages compared with previous methods: (a) the proposed method can extract global common, local common, and distinctive features automatically; (b) various distributed datasets can be processed simultaneously as long as distributions are in exponential family. The results of numerical experiments demonstrate that the proposed method outperforms conventional methods for recommendation system problems.
