Recent results have lead to substantial progress in understanding the role of disorder in the (de)localization transition of polymer pinning models. Notably, there is an understanding of the crucial issue of disorder relevance and irrelevance that is now rigorous. In this work, we exploit interpolation and replica coupling methods to obtain sharper results on the irrelevant disorder regime of p...

In this paper, we examine an approach to feature selection designed to handle domains that involve both irrelevant and interacting features. We review the reasons this situation poses challenges to both nearest neighbor and decision-tree methods, then describe a new algorithm OBLIVION that carries out greedy pruning of oblivious decision trees. We summarize the results of experiments with artif...
