A Riemannian low-rank method for optimization over semidefinite matrices with block-diagonal constraints
N Boumal - arxiv preprint arxiv:1506.00575, 2015 - arxiv.org
We propose a new algorithm to solve optimization problems of the form $\min f (X) $ for a
smooth function $ f $ under the constraints that $ X $ is positive semidefinite and the …
