    • An Empirical Comparison of SNoW and SVMs for Face Detection 

      Alvira, Mariano; Rifkin, Ryan (2001-01-01)
      Impressive claims have been made for the performance of the SNoW algorithm on face detection tasks by Yang et. al. [7]. In particular, by looking at both their results and those of Heisele et. al. [3], one could infer that ...

    • Policy Improvement for POMDPs Using Normalized Importance Sampling 

      Shelton, Christian R. (2001-03-20)
      We present a new method for estimating the expected return of a POMDP from experience. The estimator does not assume any knowle ge of the POMDP and allows the experience to be gathered with an arbitrary set of policies. ...

    • Observations on Cortical Mechanisms for Object Recognition andsLearning 

      Poggio, Tomaso; Hurlbert, Anya (1993-12-01)
      This paper sketches a hypothetical cortical architecture for visual 3D object recognition based on a recent computational model. The view-centered scheme relies on modules for learning from examples, such as Hyperbf-like ...
