Zhijian Yuan: Advances in independent component analysis and nonnegative matrix factorization

Our colleague, Zhijian Yuan, defended his doctoral dissertation "Advances in independent component analysis and nonnegative matrix factorization" today. The opponent was Prof. Fabian Theis from Helmholz Zentrum München and he provided very interesting and insightful discussion on Zhijian's work.

The thesis is theoretical work and develops and analyzes independent component analysis (ICA) and nonnegative matrix factorilization (NMF). They are both interesting methods from a cognitive point of view as they can find interesting and understandable features in an unsupervised fashion without any labeled training examples.
