Classification with Sparse Overlapping Groups

no code implementations18 Feb 2014 Nikhil Rao, Robert Nowak, Christopher Cox, Timothy Rogers

In this paper, we are interested in a less restrictive form of structured sparse feature selection: we assume that while features can be grouped according to some notion of similarity, not all features in a group need be selected for the task at hand.

Sparse Overlapping Sets Lasso for Multitask Learning and its Application to fMRI Analysis

no code implementations NeurIPS 2013 Nikhil Rao, Christopher Cox, Robert Nowak, Timothy Rogers

In this paper, we are interested in a less restrictive form of multitask learning, wherein (1) the available features can be organized into subsets according to a notion of similarity and (2) features useful in one task are similar, but not necessarily identical, to the features best suited for other tasks.
