Jong-Shi Pang University of Southern California Title: Structural Properties of Affine Sparsity Constraints Abstract: We introduce a new constraint system for sparse variable selection in statistical learning. Such a system arises when there are logical conditions on the sparsity of certain unknown model parameters that need to be incorporated into their selection process. Formally, extending a cardinality constraint, an affine sparsity constraint (ASC) is defined by a linear inequality with two sets of variables: one set of continuous variables…
Following the University's Commencement ceremony on May 14th, the Department of Statistics and Operations Research will have a brief ceremony to recognize the graduates from our B.S., M.S., and Ph.D. programs. This ceremony will take place at 1:00 PM in the Genome Science Building, room G100 and will be followed by an informal reception.
