  • Moses, Joel (1968-03-01)
    The SARGE program is a prototype of a program which is intended to be used as an adjacent to regular classroom work in freshman calculus. Using SARGE, students can type their step-by-step solution to an indefinite ...
  • Yuille, A.L.; Poggio, T. (1983-06-01)
    We characterize some properties of the zero-crossings of the laplacian of signals - in particular images - filtered with linear filters, as a function of the scale of the filter (following recent work by A. Witkin, 1983). ...
  • Holloway, Jack; Steel, Guy Lewis, Jr.; Sussman, Gerald Jay; Bell, Alan (1980-01-01)
    We have designed and implemented a single-chip microcomputer (which we call SCHEME-79) which directly interprets a typed pointer variant of SCHEME, a dialect of the language LISP. To support this interpreter the chip ...
  • Wu, Henry M. (1988-08-01)
    I describe the design and implementation plans for a computer that is optimized as a microcoded interpreter for Scheme. The computer executes SCode, a typed-pointer representation. The memory system has low-latency as ...
  • Berlin, Andrew A.; Wu, Henry M. (1988-04-01)
    Scheme86 is a computer system designed to interpret programs written in the Scheme dialect of Lisp. A specialized architecture, coupled with new techniques for optimizing register management in the interpreter, allows ...
  • Sussman, Gerald J.; Steele, Guy L., Jr. (1975-12-01)
    Inspired by ACTORS [Greif and Hewitt] [Smith and Hewitt], we have implemented an interpreter for a LISP-like language, SCHEME, based on the lambda calculus [Church], but extended for side effects, multiprocessing, and ...
  • Kornfeld, William A.; Hewitt, Carl (1981-01-01)
    Scientific communnities have proven to be extremely successful at solving problems. They are inherently parallel systems and their macroscopic nature makes them amenable to careful study. In this paper the character of ...
  • Sordillo, Donald (1966-10-01)
    This program will take a list of display instructions and cause it to be plotted. For further or more detailed information consult with Michael Speciner.
  • Edwards, Daniel J. (1963-12-01)
    A principal limitation of LISP processors in many computations is that of inadequate primary random-access storage. This paper explores several methods of using a secondary storage medum (such as drums, disk files or magetic ...
  • Rees, Jonathan A. (1996-03-13)
    Cooperation between independent agents depends upon establishing adegree of security. Each of the cooperating agents needs assurance that the cooperation will not endanger resources of value to that agent. In a computer ...
  • Weinshall, Daphna (1988-09-01)
    A unique matching is a stated objective of most computational theories of stereo vision. This report describes situations where humans perceive a small number of surfaces carried by non-unique matching of random dot ...
  • Lieberman, Henry (1982-02-01)
    An important skill in programming is being able to visualize the operation of procedures, both for constructing programs and debugging them. Tinker is a programming environment for Lisp that enables the programmer to ...
  • Doyle, Jon; London, Philip (1980-02-01)
    This article presents an overview of research in an area loosely called belief revision. Belief revision concentrates on the issue of revising systems of beliefs to reflect perceived changes in the environment or ...
  • Koch, Christof; Ullman, Shimon (1984-01-01)
    This study addresses the question of how simple networks can account for a variety of phenomena associated with the shift of a specialized processing focus across the visual scene. We address in particular aspects of ...
  • Wolf, Lior; Amnon Shashua,; Mukherjee, Sayan (2004-01-27)
    Array technologies have made it possible to record simultaneously the expression pattern of thousands of genes. A fundamental problem in the analysis of gene expression data is the identification of highly relevant genes ...
  • Brooks, Rodney A.; Flynn, Anita M.; Marill, Thomas (1987-08-01)
    We report on experiments with a mobile robot using one vision process (forward motion vision) to calibrate another (stereo vision) without resorting to any external units of measurement. Both are calibrated to a velocity ...
  • Edelman, Shimon; Weinshall, Daphna (1989-08-01)
    We explore representation of 3D objects in which several distinct 2D views are stored for each object. We demonstrate the ability of a two-layer network of thresholded summation units to support such representations. Using ...
  • Attardi, Giuseppe; Simi, Maria (1981-08-01)
    Omega is a description system for knowledge embedding which incorporates some of the attractive modes of expression in common sense reasoning such as descriptions, inheritance, quantification, negation, attributions ...
  • Barber, Gerald; Jong, Peter de; Hewitt, Carl (1983-04-01)
    Present day computer systems cannot implement much of the work carried out in organizations such as: planning, decision making, analysis, and dealing with unanticipated situations. Such organizational activities have ...
  • Steck, Harald; Jaakkola, Tommi S. (2003-02-25)
    In this paper, we present an approach to discretizing multivariate continuous data while learning the structure of a graphical model. We derive the joint scoring function from the principle of predictive accuracy, which ...
