- W1890797 abstract "We summarize computational experience with algorithms based on the Spingarn Partial Inverse proximal method for Huber-M estimation. The result is a family of highly parallel primal-dual algorithms that are globally convergent and attractive for large scale problems. The approach is easily extended to handle constrained problems. To obtain an efficient implementation, remedies are introduced to ensure efficiency in case of highly degenerate situations. Here, several mechanisms are investigated for reducing the execution time. Problems with bundle of M-estimators are investigated. In computational practice, appropriate choice of start point and robust data pre-conditioning are shown to result in speed-up performance, even for box constrained problems." @default.
