Partitioning Data on Features or Samples in Communication-Efficient Distributed Optimization?
Chenxin Ma, Martin Takáč
In this paper we study the effect of the way that the data is partitioned in distributed optimization. The original DiSCO algorithm [Communication-Efficient Distributed Optimizatio…
Dual Free Adaptive Mini-batch SDCA for Empirical Risk Minimization
Xi He, Martin Takáč
In this paper we develop dual free mini-batch SDCA with adaptive probabilities for regularized empirical risk minimization. This work is motivated by recent work of Shai Shalev-Shw…
Hybrid Methods in Solving Alternating-Current Optimal Power Flows
Alan C. Liddell, Jie Liu, Jakub Marecek +1
Many steady-state problems in power systems, including rectangular power-voltage formulations of optimal power flows in the alternating-current model (ACOPF), can be cast as polyno…
A Low-Rank Coordinate-Descent Algorithm for Semidefinite Programming Relaxations of Optimal Power Flow
Jakub Marecek, Martin Takac
The alternating-current optimal power flow (ACOPF) is one of the best known non-convex non-linear optimisation problems. We present a novel re-formulation of ACOPF, which is based…
