    • Selecting Relevant Genes with a Spectral Approach 

      Wolf, Lior; Amnon Shashua,; Mukherjee, Sayan (2004-01-27)
      Array technologies have made it possible to record simultaneously the expression pattern of thousands of genes. A fundamental problem in the analysis of gene expression data is the identification of highly relevant genes ...

    • Risk Bounds for Mixture Density Estimation 

      Rakhlin, Alexander; Panchenko, Dmitry; Mukherjee, Sayan (2004-01-27)
      In this paper we focus on the problem of estimating a bounded density using a finite combination of densities from a given class. We consider the Maximum Likelihood Procedure (MLE) and the greedy procedure described by ...

    • On the difficulty of feature-based attentional modulations in visual object recognition: A modeling study. 

      Schneider, Robert; Riesenhuber, Maximilian (2004-01-14)
      Numerous psychophysical experiments have shown an important role for attentional modulations in vision. Behaviorally, allocation of attention can improve performance in object detection and recognition tasks. At the neural ...
