Abstract: We investigate the problem of finding inner approximations of positive semidefinite (PSD) cones. We develop a novel decomposition framework of the PSD cone by means of conical combinations ...

Abstract: In this paper, we study the problem of facial expression recognition using a novel space-time geometric representation. We describe the temporal evolution of facial landmarks as parametrized ...

The first post (What is convex optimization？common constraints and objectives) introduced several basic cones supported in a conic optimization solver: zero cone, nonnegative cone, second-order cone, ...
