    • A Connection Between GRBF and MLP 

      Maruyama, Minoru; Girosi, Federico; Poggio, Tomaso (1992-04-01)
      Both multilayer perceptrons (MLP) and Generalized Radial Basis Functions (GRBF) have good approximation properties, theoretically and experimentally. Are they related? The main point of this paper is to show that for ...

    • Green Theorems and Qualitative Properties of the Optical Flow 

      Poggio, Tomaso; Verri, Allessandro; Torre, Vincent (1991-04-01)
      How can one compute qualitative properties of the optical flow, such as expansion or rotation, in a way which is robust and invariant to the position of the focus of expansion or the center of rotation? We suggest a ...

    • Models of Noise and Robust Estimates 

      Girosi, Federico (1991-11-01)
      Given n noisy observations g; of the same quantity f, it is common use to give an estimate of f by minimizing the function Eni=1(gi-f)2. From a statistical point of view this corresponds to computing the Maximum likelihood ...
