Abstract: As the availability and scope of complex data increase in both scientific and engineering fields, developing statistical tools to discover latent structures and hidden explanatory factors has become a major theme of statistic and machine learning research. Breakthrough work has recently been done on learning latent feature representations with shallow or deep architectures using a huge amount of computing resources and massive data corpora. However, some key research issues are still remaining under-addressed. In this talk, I will introduce some of our recent work on learning representations that are discriminative in specific application tasks, including classification, multi-view data analysis, social link prediction, and low-rank matrix factorization. I will share some insights on dealing with several key issues on learning latent representations, including discriminative ability, model complexity, sparsity/interpretability, and scalability.
