Using Neural Networks to Detect Line Outages from PMU Data
Ching-pei Lee, Stephen J. Wright
We propose an approach based on neural networks and the AC power flow equations to identify single- and double-line outages in a power grid using the information from phasor measur…

Distributed Block-diagonal Approximation Methods for Regularized Empirical Risk Minimization
Ching-pei Lee, Kai-Wei Chang
In recent years, there is a growing need to train machine learning models on a huge volume of data. Designing efficient distributed optimization algorithms for empirical risk minim…

Analyzing Random Permutations for Cyclic Coordinate Descent
Stephen J. Wright, Ching-Pei Lee
We consider coordinate descent methods on convex quadratic problems, in which exact line searches are performed at each iteration. (This algorithm is identical to Gauss-Seidel on t…
