Structure determination from single-molecule X-ray scattering images using stochastic gradient ascent
Steffen Schultze, D. Russell Luke, Helmut Grubmüller
Scattering experiments using ultrashort X-ray free electron laser (XFEL) pulses have opened a new path for structure determination of a wide variety of specimens, including nano-cr…

Stochastic Algorithms for Large-Scale Composite Optimization: the Case of Single-Shot X-FEL Imaging
D. Russell Luke, Steffen Schultze, Helmut Grubmüller
We apply a recently developed framework for analyzing the convergence of stochastic algorithms to the general problem of large-scale nonconvex composite optimization more generally…

Convergence in Distribution of Randomized Algorithms: The Case of Partially Separable Optimization
D. Russell Luke
We present a Markov-chain analysis of blockwise-stochastic algorithms for solving partially block-separable optimization problems. Our main contributions to the extensive literatur…
