DC Decomposition of Nonconvex Polynomials with Algebraic Techniques

2015-10-06 · Amir Ali Ahmadi, Georgina Hall

We consider the problem of decomposing a multivariate polynomial as the difference of two convex polynomials. We introduce algebraic techniques which reduce this task to linear, second order cone, and semidefinite programming. This allows us to optimize over subsets of valid difference of convex decompositions (dcds) and find ones that speed up the convex-concave procedure (CCP). We prove, however, that optimizing over the entire set of dcds is NP-hard.

Fundamental Conditions for Low-CP-Rank Tensor Completion

2017-03-31 · Morteza Ashraphijuo, Xiaodong Wang

We consider the problem of low canonical polyadic (CP) rank tensor completion. A completion is a tensor whose entries agree with the observed entries and its rank matches the given CP rank. We analyze the manifold struct…
