Frugal Splitting Operators: Representation, Minimal Lifting, and Convergence
Martin Morin, Sebastian Banert, Pontus Giselsson
We investigate frugal splitting operators for finite sum monotone inclusion problems. These operators utilize exactly one direct or resolvent evaluation of each operator of the sum…
Nonlinear Forward-Backward Splitting with Momentum Correction
Martin Morin, Sebastian Banert, Pontus Giselsson
The nonlinear, or warped, resolvent recently explored by Giselsson and Bùi-Combettes has been used to model a large set of existing and new monotone inclusion algorithms. To establ…
Sampling and Update Frequencies in Proximal Variance-Reduced Stochastic Gradient Methods
Martin Morin, Pontus Giselsson
Variance-reduced stochastic gradient methods have gained popularity in recent times. Several variants exist with different strategies for the storing and sampling of gradients and…
Cocoercivity, Smoothness and Bias in Variance-Reduced Stochastic Gradient Methods
Martin Morin, Pontus Giselsson
With the purpose of examining biased updates in variance-reduced stochastic gradient methods, we introduce SVAG, a SAG/SAGA-like method with adjustable bias. SVAG is analyzed in a…
