  • Wallach, Deborah A. (1992-09-01)
    As the number of processors in distributed-memory multiprocessors grows, efficiently supporting a shared-memory programming model becomes difficult. We have designed the Protocol for Hierarchical Directories (PHD) to ...
  • Gerber, Georg K.; Dowell, Robin D.; Jaakkola, Tommi S.; Gifford, David K. (2007-07-06)
    An important research problem in computational biology is theidentification of expression programs, sets of co-activatedgenes orchestrating physiological processes, and thecharacterization of the functional breadth of these ...
  • Jordan, Michael I.; Jacobs, Robert A. (1993-08-01)
    We present a tree-structured architecture for supervised learning. The statistical model underlying the architecture is a hierarchical mixture model in which both the mixture coefficients and the mixture components are ...
  • Isik, Leyla; Leibo, Joel Z.; Mutch, Jim; Lee, Sang Wan; Poggio, Tomaso (2011-06-17)
    We present a peripheral vision model inspired by the cortical architecture discovered by Hubel and Wiesel. As with existing cortical models, this model contains alternating layers of simple cells, which employ tuning ...
  • Ettinger, Gil J. (1987-05-01)
    This thesis describes the development of a model-based vision system that exploits hierarchies of both object structure and object scale. The focus of the research is to use these hierarchies to achieve robust recognition ...
  • Hollerbach, John M. (1975-11-01)
    An approach towards shape description, based on prototype modification and generalized cylinders, has been developed and applied to the object domains pottery and polyhedra: (1) A program describes and identifies pottery ...
  • Kaelbling, Leslie Pack; Lozano-Perez, Tomas (2010-05-07)
    In this paper we outline an approach to the integration of task planning and motion planning that has the following key properties: It is aggressively hierarchical. It makes choices and commits to them in a top-down fashion ...
  • Dunlavey, Michael R. (MIT Artificial Intelligence Laboratory, 1973-05)
    Organization of knowledge requires the flexible use of hierarchy in descriptions. This memo attempts to catalog the issues related to recognizing and executing such descriptions, drawing examples primarily from the blocks world.
  • Doyle, Jon (MIT Artificial Intelligence Laboratory, 1977-11)
    This paper discusses a number of problems faced in communicating expertise and common sense to a computer, and the approaches taken by several current knowledge representation languages towards solving these problems. The ...
  • Levin, Anat; Glasner, Daniel; Xiong, Ying; Durand, Fredo; Freeman, William; Matusik, Wojciech; Zickler, Todd (2013-04-24)
    This manuscript completes the analysis of our SIGGRAPH 2013 paper "Fabricating BRDFs at High Spatial Resolution Using Wave Optics" in which photolithography fabrication was used for manipulating reflectance effects. While ...
  • Morrison, Jerry Howard (MIT Artificial Intelligence Laboratory, 1977-05)
    PLASMA (for PLAnner-like System Modeled on Actors) is a message-passing computer language based on actor semantics. Since every event in the system is the receipt of a message actor by a target actor, a complete history ...

    Winston, Patrick H. (1968-08-01)
    This memo originally had two parts. The first dealt with certain deficiencies in an early version of Guzman's program, SEE. The problems have been fixed, and the corresponding discussion has been dropped from this ...
  • Buelthoff, Heinrich H.; Edelman, Shimon Y.; Tarr, Michael J. (1994-04-01)
    We discuss a variety of object recognition experiments in which human subjects were presented with realistically rendered images of computer-generated three-dimensional objects, with tight control over stimulus shape, ...
  • Fleming, Roland W.; Dror, Ron O.; Adelson, Edward H. (2001-10-21)
    Under normal viewing conditions, humans find it easy to distinguish between objects made out of different materials such as plastic, metal, or paper. Untextured materials such as these have different surface reflectance ...
  • Dig, Danny; Marrero, John; Ernst, Michael D. (2008-09-05)
    For several decades, programmers have relied onMooreâ s Law to improve the performance of their softwareapplications. From now on, programmers need to programthe multi-cores if they want to deliver efficient code. Inthe ...
  • Smith, Brian Cantwell (MIT Artificial Intelligence Laboratory, 1978-11)
    In the summer of 1978 a decision was made to devote a special issue of the SIGART newsletter to the subject of knowledge representation research. To assist in ascertaining the current state of people's thinking on this ...
  • Liang, Percy; Srebro, Nati (2005-01-03)
    Current approximation algorithms for maximum weight {\em hypertrees} find heavy {\em windmill farms}, and are based on the fact that a constant ratio (for constant width $k$) of the weight of a $k$-hypertree can be captured ...
  • Danofsky, Murray Elias (1976-02-01)
    This paper presents a system for understanding the concept of near and far, weighing such factors as purpose of the judgement, dimensions of the objects, absolute size of the distance, and size of the distance relative ...
  • Hollerbach, John (MIT Artificial Intelligence Laboratory, 1975-07)
    Handwriting is shown to be composed mainly of cup-shaped strokes lasting approximately 200 msec. The strokes are based on a hexagonal pattern, with quantized slopes and lengths. Each side of the hexagon is produced by a ...
  • Teevan, Jaime (2004-06-18)
    This paper investigates how people return to information in a dynamic information environment. For example, a person might want to return to Web content via a link encountered earlier on a Web page, only to learn that the ...
