A generalised log-determinant regularizer for online semi-definite programming and its applications

no code implementations10 Dec 2020 Yaxiong Liu, Ken-ichiro Moridomi, Kohei Hatano, Eiji Takimoto

We consider a variant of online semi-definite programming problem (OSDP): The decision space consists of semi-definite matrices with bounded $\Gamma$-trace norm, which is a generalization of trace norm defined by a positive definite matrix $\Gamma.$ To solve this problem, we utilise the follow-the-regularized-leader algorithm with a $\Gamma$-dependent log-determinant regularizer.
