    • On Convergence Properties of the EM Algorithm for Gaussian Mixtures 

      Jordan, Michael; Xu, Lei (1995-04-21)
      "Expectation-Maximization'' (EM) algorithm and gradient-based approaches for maximum likelihood learning of finite Gaussian mixtures. We show that the EM step in parameter space is obtained from the gradient via a ...

    • View-Based Strategies for 3D Object Recognition 

      Sinha, Pawan; Poggio, Tomaso (1995-04-21)
      A persistent issue of debate in the area of 3D object recognition concerns the nature of the experientially acquired object models in the primate visual system. One prominent proposal in this regard has expounded the ...

    • Example Based Learning for View-Based Human Face Detection 

      Sung, Kah Kay; Poggio, Tomaso (1995-01-24)
      We present an example-based learning approach for locating vertical frontal views of human faces in complex scenes. The technique models the distribution of human face patterns by means of a few view-based "face'' and ...
