Randomized Block Coordinate DC Programming
Hoomaan Maskan, Paniz Halvachi, Suvrit Sra +1
We introduce an extension of the Difference of Convex Algorithm (DCA) in the form of a randomized block coordinate approach for problems with separable structure. For coordinat…
First-Order Methods for Linearly Constrained Bilevel Optimization
Guy Kornowski, Swati Padmanabhan, Kai Wang +2
Algorithms for bilevel optimization often encounter Hessian computations, which are prohibitive in high dimensions. While recent works offer first-order methods for unconstrained b…
Riemannian Bilevel Optimization
Sanchayan Dutta, Xiang Cheng, Suvrit Sra
We develop new algorithms for Riemannian bilevel optimization. We focus in particular on batch and stochastic gradient-based methods, with the explicit goal of avoiding second-orde…
