  • Marr, D.; Hildreth, E. (1979-04-01)
    A theory of edge detection is presented.
  • Poggio, Tomaso (1990-12-01)
    I wish to propose a quite speculative new version of the grandmother cell theory to explain how the brain, or parts of it, may work. In particular, I discuss how the visual system may learn to recognize 3D objects. The ...
  • Marr, D.; Poggio, T. (1977-11-01)
    An algorithm is proposed for solving the stereoscopic matching problem. The algorithm consists of five steps: 1.) Each image is filtered with bar masks of four sizes that vary with eccentricity; the equivalent filters ...
  • Poggio, Tomaso; Girosi, Federico (1989-07-01)
    Learning an input-output mapping from a set of examples, of the type that many neural networks have been constructed to perform, can be regarded as synthesizing an approximation of a multi-dimensional function, that ...
  • Fahlman, Scott E. (1975-05-01)
    This paper describes progress to date in the development of a system for representing various forms of real-world knowledge. The knowledge is stored in the form of a net of simple parallel processing elements, which ...
  • Lieberman, Henry (1981-05-01)
    As advances in computer architecture and changing economics make feasible machines with large-scale parallelism, Artificial Intelligence will require new ways of thinking about computation that can exploit parallelism ...
  • McAllester, D.; Henlenryck, P. Van; Kapur, T. (1995-05-01)
    This paper addresses the problem of nonlinear multivariate root finding. In an earlier paper we described a system called Newton which finds roots of systems of nonlinear equations using refinements of interval methods. ...
  • Marill, Thomas (1995-10-01)
    We provide a theory of the three-dimensional interpretation of a class of line-drawings called p-images, which are interpreted by the human vision system as parallelepipeds ("boxes"). Despite their simplicity, p-images ...
  • Katz, Boris (1980-12-01)
    This paper outlines a three-step plan for generating English text from any semantic representation by applying a set of syntactic transformations to a collection of kernel sentences. The paper focuses on describing a ...
  • McAllester, David A. (1978-05-01)
    Truth maintenance systems have been used in recently developed problem solving systems. A truth maintenance system (TMS) is designed to be used by deductive systems to maintain the logical relations among the beliefs ...
  • Skordos, P. A. (1992-09-01)
    A time-reversible Maxwell's demon is demonstrated which creates a density difference between two chambers initialized to have equal density. The density difference is estimated theoretically and confirmed by computer ...
  • White, John (1968-03-01)
    This memo written in the style and convention of A.I. memo No. 116A, may be considered an addendum thereto. It should prove to be a welcome updating on the LISP system.
  • Levin, Michael (1966-01-01)
    The concept of free as in "free group" is generalized to any first order theory. An interesting class of homomorphisms between models is discussed. Relations between model theory and abelian categories are discussed ...
  • Levin, Michael (1965-05-01)
    The concept of "free" as in free group and free semi-group is extended to arbitrary first order theories. Every consistent theory has free models. Some problems of obtaining a categorical theory of models are discussed.
  • Perlman, Radia (1974-12-01)
    TORTIS is a device for preschool children to communicated with and program the turtle. It consistst of several boxes (currently 3 button boxes and two blox boxes) designed so that only a few new concepts are introduced ...
  • Brady, Mike (1980-09-01)
    This paper is the first of a series aimed at developing a theory of early visual processing in reading. We suggest that there has been a close parallel in the development of theories of reading and theories of vision ...
  • Barton, G. Edward, Jr. (1984-07-01)
    Parser design lags behind linguistic theory. While modern transformational grammar has largely abandoned complex, language-specific rule systems in favor of modular subsystems of principles and parameters, the rule ...
  • Minsky, Marvin (1979-09-01)
    We can solve many problems of Energy, Health, Productivity, and Environmental Quality by improving the technology of remote control. This will produce Nuclear Safety and Security, Advances in Mining, Increases in ...
  • Rich, Charles; Waters, Richard C. (1986-07-01)
    Requirements acquisition is one of the most important and least well supported parts of the software development process. The Requirements Apprentice (RA) will assist a human analyst in the creation and modification ...
  • Ponce, Jean; Brady, Michael (1985-04-01)
    This paper reports progress toward the development of a representation of significant surface changes in dense depth maps. We call the representation the Surface Primal Sketch by analogy with representation of intensity ...
