Improving "Fast Iterative Shrinkage-Thresholding Algorithm": Faster, Smarter and Greedier
Jingwei Liang, Tao Luo, Carola-Bibiane Schönlieb
The "fast iterative shrinkage-thresholding algorithm", a.k.a. FISTA, is one of the most well-known first-order optimisation scheme in the literature, as it achieves the worst-case…
Faster FISTA
Jingwei Liang, Carola-Bibiane Schönlieb
The ``fast iterative shrinkage-thresholding algorithm'', a.k.a. FISTA, is one of the most widely used algorithms in the literature. However, despite its optimal theoretical $O(1/k^…
Partial smoothness and constant rank
Adrian S. Lewis, Jingwei Liang
The idea of partial smoothness in optimization blends certain smooth and nonsmooth properties of feasible regions and objective functions. As a consequence, the standard first-orde…
Local Convergence Properties of SAGA/Prox-SVRG and Acceleration
Clarice Poon, Jingwei Liang, Carola-Bibiane Schönlieb
Over the past ten years, driven by large scale optimisation problems arising from machine learning, the development of stochastic optimisation methods have witnessed a tremendous g…
Convergence rates of Forward--Douglas--Rachford splitting method
Cesare Molinari, Jingwei Liang, Jalal Fadili
Over the past years, operator splitting methods have become ubiquitous for non-smooth optimization owing to their simplicity and efficiency. In this paper, we consider the Forward-…
