Alternating direction method of multipliers for penalized zero-variance discriminant analysis

no code implementations21 Jan 2014 Brendan P. W. Ames, Mingyi Hong

To accomplish this task, we propose a heuristic, called sparse zero-variance discriminant analysis (SZVD), for simultaneously performing linear discriminant analysis and feature selection on high dimensional data.

Guaranteed clustering and biclustering via semidefinite programming

no code implementations16 Feb 2012 Brendan P. W. Ames

As in our analysis of the densest k-disjoint-clique problem, we show that the correct partition of the objects and features can be recovered from the optimal solution of a semidefinite program in the case that the given data consists of several disjoint sets of objects exhibiting similar features.
