SCoRS—A Method Based on Stability for Feature Selection and Mapping in Neuroimaging

Jane M. Rondina, Tim Hahn, Leticia de Oliveira, Andre F. Marquand, Thomas Dresler, Thomas Leitner, Andreas J. Fallgatter, John Shawe-Taylor, Janaina Mourao-Miranda
2014 IEEE Transactions on Medical Imaging  
In the current paper we propose a new approach for selecting features: SCoRS (survival count on random subsamples) based on a recently proposed Stability Selection theory.  ...  SCoRS relies on the idea of choosing relevant features that are stable under data perturbation. Data are perturbed by iteratively sub-sampling both features (subspaces) and examples.  ...  Searchlight [19] is a technique proposed for multivariate mapping based on local neighborhood.  ...

2015 arXiv   pre-print
However, it fails to make explicit use of the correlation property or structural information of these discriminative features and leads to large false negative rates.  ...  Thus, we propose a new variant on stability selection "randomized structural sparsity", which incorporates the idea of structural sparsity.  ...  Let us first briefly explain subsampling-based stability.  ...
