    • Visual Segmentation without Classification in a Model of the Primary Visual Cortex 

      Li, Zhaoping (1997-08-01)
      Stimuli outside classical receptive fields significantly influence the neurons' activities in primary visual cortex. We propose that such contextual influences are used to segment regions by detecting the breakdown of ...
    • Properties of Support Vector Machines 

      Pontil, Massimiliano; Verri, Alessandro (1997-08-01)
      Support Vector Machines (SVMs) perform pattern recognition between two point classes by finding a decision surface determined by certain points of the training set, termed Support Vectors (SV). This surface, which in some ...
    • Estimating Dependency Structure as a Hidden Variable 

      Meila, Marina; Jordan, Michael I.; Morris, Quaid (1997-06-01)
      This paper introduces a probability model, the mixture of trees that can account for sparse, dynamically changing dependence relationships. We present a family of efficient algorithms that use EMand the Minimum Spanning ...
