Scalable Hessian-free Proximal Conjugate Gradient Method for Nonconvex and Nonsmooth Optimization
Yiming Zhou, Wei Dai
This work studies a composite minimization problem involving a differentiable function q and a nonsmooth function h, both of which may be nonconvex. This problem is ubiquitous in s…

Proximal Dogleg Opportunistic Majorization for Nonconvex and Nonsmooth Optimization
Yiming Zhou, Wei Dai
We consider minimizing a function consisting of a quadratic term and a proximable term which is possibly nonconvex and nonsmooth. This problem is also known as scaled proximal oper…
