Large-Scale Structured Sparse Learning


Jieping Ye , Arizona State University

Abstract:
Sparse methods have been shown to be a versatile and powerful tool for biomedical data analysis. In this talk, we consider sparse methods for (1) variable selection where the structure over the features can be represented as an undirected graph or a collection of disjoint groups or a tree, (2) multi-source data fusion with a "blockwise" data missing pattern, and (3) network construction. We address the computational challenge by designing novel screening strategies which scale sparse methods to large-size problems.
