Abstract: In recent years, there has been a growing interest in mathematical models leading to the minimization, in a symmetric matrix space, of a Bregman divergence coupled with a regularization term. We address problems of this type within a general framework where the regularization term is split into two parts, one being a spectral function while the other is arbitrary. A Douglas-Rachford approach is proposed to address such problems, and a list of proximity operators is provided allowing us to consider various choi…
