Research Interests

"Nothing is more practical than a good theory." --Vladimir Vapnik

I am mostly interested in theoretical computer science and different aspects of mathematics, especially functional analysis and geometry. From time to time I contribute to statistical machine learning theory, including theory and application of deep learning, subspace clustering, manifold learning, sparse representation and compressive sensing, nonparametric models, probabilistic graphical models and generalization analysis of classification, semi-supervised learning and clustering.

In my early years I also conducted research on computer vision and computer graphics. Click to see the details

Our work establishs almost surely equivalence between L0 sparsity and subspace detection property, under the mild condition of i.i.d. data generation and nondegenerate distribution. This is much milder than previous conditions required by L1 sparse subspace clustering literature. Click to see the key points in the talk
