    • Against Direct Perception 

      Ullman, S. (1980-03-01)
      Central to contemporary cognitive science is the notion that mental processes involve computations defined over internal representations. This notion stands in sharp contrast with another prevailing view ??e direct ...
    • An AI Approach to English Morphemic Analysis 

      Winograd, Terry (1971-02-01)
      This paper illustrated an approach toward understanding natural language through the techniques of artificial intelligence. It explores the structure of English word-endings both morpho-graphemically and semantically. It ...
    • AI Based Personal Learning Environments: Directions for Long Term Research 

      Goldstein, Ira P.; Miller, Mark L. (1976-12-01)
      The application of artificial intelligence (AI) techniques to the design of personal learning environments is an enterprise of both theoretical and practical interest. In the short term, the process of developing and ...
    • Algebraic Functions For Recognition 

      Shashua, Ammon (1994-01-01)
      In the general case, a trilinear relationship between three perspective views is shown to exist. The trilinearity result is shown to be of much practical use in visual recognition by alignment --- yielding a direct method ...
    • An Algorithm for Bootstrapping Communications 

      Beal, Jacob (2001-08-13)
      I present an algorithm which allows two agents to generate a simple language based only on observations of a shared environment. Vocabulary and roles for the language are learned in linear time. Communication is robust and ...
    • An Algorithm for Group Formation and Maximal Independent Set in an Amorphous Computer 

      Nagpal, Radhika; Coore, Daniel (1998-02-01)
      Amorphous computing is the study of programming ultra-scale computing environments of smart sensors and actuators cite{white-paper}. The individual elements are identical, asynchronous, randomly placed, embedded and ...
    • The Alignment of Objects with Smooth Surfaces 

      Ullman, Shimon; Basri, Ronen (1988-07-01)
      This paper examines the recognition of rigid objects bounded by smooth surfaces using an alignment approach. The projected image of such an object changes during rotation in a manner that is difficult to predict. A ...
    • The Alignment of Objects With Smooth Surfaces: Error Analysis of the Curvature Method 

      Basri, Ronen (1991-11-01)
      The recognition of objects with smooth bounding surfaces from their contour images is considerably more complicated than that of objects with sharp edges, since in the former case the set of object points that generates ...
    • The Alpha-Beta Heuristic 

      Edwards, D.J.; Hart, T.P. (1961-12-01)
      The Alpha-Beta heuristic is a method for pruning unneeded branches from the move tree of a game. The algorithm makes use of information gained about part of the tree to reject those branches which will not affect the ...
    • An Alternative to Using the 3D Delaunay Tessellation for Representing Freespace 

      Braunegg, David J. (1989-09-01)
      Representing the world in terms of visible surfaces and the freespacesexisting between these surfaces and the viewer is an important problemsin robotics. Recently, researchers have proposed using the 3DsDelaunay ...
    • Ambiguities of a Motion Field 

      Negahdaripour, Shahriar (1987-01-01)
      We study the conditions under which a perspective motion field can have multiple interpretations. Furthermore, we show that in most cases, the ambiguity in the interpretation of a motion field can be resolved by imposing ...
    • AMORD: A Deductive Procedure System 

      Kleer, Johan de; Doyle, Jon; Rich, Charles; Steele, Guy L., Jr.; Sussman, Gerald Jay (1978-01-01)
      We have implemented an interpreter for a rule-based system, AMORD, based on a non-chronological control structure and a system of automatically maintained data-dependencies. The purpose of this paper is to serve as a ...
    • Amorphous Computing 

      Abelson, Harold; Allen, Don; Coore, Daniel; Hanson, Chris; Homsy, George; e.a. (1999-08-29)
      Amorphous computing is the development of organizational principles and programming languages for obtaining coherent behaviors from the cooperation of myriads of unreliable parts that are interconnected in unknown, ...
    • Analog "Neuronal" Networks in Early Vision 

      Koch, Christof; Marroquin, Jose; Yuille, Alan (1985-06-01)
      Many problems in early vision can be formulated in terms of minimizing an energy or cost function. Examples are shape-from-shading, edge detection, motion analysis, structure from motion and surface interpolation ...
    • An Analog Model of Computation for the Ill-Posed Problems of Early Vision 

      Poggio, Tomaso; Koch, Christof (1984-05-01)
      A large gap exists at present between computational theories of vision and their possible implementation in neural hardware. The model of computation provided by the digital computer is clearly unsatisfactory for the ...
    • Analysis of a Cooperative Stereo Algorithm 

      Marr, D.; G. Palm,; Poggio, T. (1977-10-01)
      Marr & Poggio (1976) recently described a cooperative algorithm that solves the correspondence problem for stereopsis. This article uses a probabilistic technique to analyze the convergence of that algorithm, and ...
    • Analysis of Differential and Matching Methods for Optical Flow 

      Little, James J.; Verri, Alessandro (1988-08-01)
      Several algorithms for optical flow are studied theoretically and experimentally. Differential and matching methods are examined; these two methods have differing domains of application- differential methods are best ...
    • Analysis of Occluding Contour 

      Marr, D. (1976-10-01)
      Almost nothing can be deduced about a general 3-D surface given only its occluding contours in an image, yet contour information is easily and effectively used by us to infer the shape of a surface. Therefore, implicit ...
