  • Felzenszwalb, Pedro F. (2003-08-08)
    We present a set of techniques that can be used to represent anddetect shapes in images. Our methods revolve around a particularshape representation based on the description of objects usingtriangulated polygons. This ...

  • Marr, David; Vaina, Lucia (1980-10-01)
    The problems posed by the representation and recognition of the movements of 3-D shapes are analyzed. A representation is proposed for the movements of shapes that lie within the scope of Marr & Nishihara's (1978) 3-D ...
  • Marr, D.; Nishihara, H.K. (1976-08-01)
    A method is given for representing 3-D shapes. It is based on a hierarchy of stick figures (called 3-D models), where each stick corresponds to an axis in the shape's generalized cone representation. Although the ...
  • Marr, D.; Nishihara, H.K. (1977-05-01)
    The human visual process can be studied by examining the computational problems associated with deriving useful information from retinal images. In this paper, we apply this approach to the problem of representing ...
  • Riley, Michael Dennis (1981-09-01)
    This thesis explores how to represent image texture in order to obtain information about the geometry and structure of surfaces, with particular emphasis on locating surface discontinuities. Theoretical and psychophysical ...
  • Simmons, Reid G.; Davis, Randall (1983-04-01)
    This paper explores representations used to reason about objects which change over time and the processes which cause changes. Specifically, we are interested in solving a problem known as geologic interpretation. To ...
  • Simmons, Reid Gordon (1983-12-01)
    Geologic interpretation is the task of inferring a sequence of events to explain how a given geologic region could have been formed. This report describes the design and implementation of one part of a geologic interpretation ...
  • Doyle, Richard J. (MIT Artificial Intelligence Laboratory, 1983-01)
    Change pervades every moment of our lives. Much of our success in dealing with a constantly changing world is based in common-sense physical reasoning about processes and physical systems. Processes are the way quantities ...
  • Koton, Phyllis A. (1981-11)
    This paper considers two constraint systems, that of Steele and Sussman, and Alan Borning's Thinglab. Some functional difficulties in these systems are discussed. A representation of constraint systems using the description ...
  • Kuipers, Benjamin J. (1977-07-01)
    This dissertation presents a model of the knowledge a person has about the spatial structure of a large-scale environment: the "cognitive map". The functions of the cognitive map are to assimilate new information about ...
  • Wormald, Nicholas; Richards, Whitman (2009-03-30)
    Understanding the dynamics of network evolution rests in part on the representation chosen to characterize the evolutionary process. We offer a simple, three-parameter representation based on subgraphs that capture three ...
  • Grossman, Richard W. (MIT Artificial Intelligence Laboratory, 1975-01)
    The issue of how to represent the "meaning" of an utterance is central to the problem of computer understanding of natural language. Rather than relying on ad-hoc structures or forcing the complexities of natural language ...
  • Marr, D. (1977-05-01)
    Vision is the construction of efficient symbolic descriptions from images of the world. An important aspect of vision is the choice of representations for the different kinds of information in a visual scene. In the ...
  • Reubenstein, Howard (MIT Artificial Intelligence Laboratory, 1986-09)
    The Requirements Analyst's APprentice (RAAP) partially automates the modeling process involved in creating a software requirement. It uses knowledge of the specific domain and general experience regarding software requirements ...
  • Singer, Neil C. (1989-02-01)
    Control of machines that exhibit flexibility becomes important when designers attempt to push the state of the art with faster, lighter machines. Three steps are necessary for the control of a flexible planet. First, ...
  • Micali, Silvio; Chen, Jing (2008-12-17)
    We present various resilient auction mechanisms for a good in limited supply. Our mechanisms achieve both player-knowledge and aggregated player-knowledge benchmarks.
  • Micali, Silvio; Chen, Jing (2008-10-08)
    We put forward a new mechanism achieving a high benchmark for (both revenue and) the sum of revenue and efficiency in truly combinatorial auctions. Notably, our mechanism guarantees its performance (1) in a very adversarial ...
  • Micali, Silvio; Valiant, Paul (2008-11-13)
    Dominant-strategy truthfulness is traditionally considered the best possible solution concept in mechanism design, as it enables one to predict with confidence which strategies INDEPENDENT players will actually choose. ...
  • Jaggi, Sidharth; Langberg, Michael; Katti, Sachin; Ho, Tracy; Katabi, Dina; Medard, Muriel (2006-08-05)
    Network coding substantially increases network throughput. But since it involves mixing of information inside the network, a single corrupted packet generated by a malicious node can end up contaminating all the information ...
