  • Bergman, Ruth (1995-05-05)
    This thesis examines the problem of an autonomous agent learning a causal world model of its environment. Previous approaches to learning causal world models have concentrated on environments that are too "easy" ...
  • Martin, William A. (1968-02-01)
    Determination of the minimum resources required to parse a language generated by a given context free grammar is an intriguing and yet unsolved problem. It seems plausible that any unambiguous context free grammar could ...
  • Stein, Gideon P. (1996-12-01)
    This paper describes a new method for lens distortion calibration using only point correspondences in multiple views, without the need to know either the 3D location of the points or the camera locations. The standard ...
  • Waters, Richard C. (1983-02-01)
    Many loops can be more easily understood and manipulated if they are viewed as being built up out of operations on sequences of values. A notation is introduced which makes this viewpoint explicit. Using it, loops can ...
  • Bullwinkle, Candace (1977-05-01)
    This paper presents a discussion of means of describing the discourse and its components which makes speech act interpretation and reference disambiguation possible with minimal search of the knowledge in the database. ...
  • Poggio, Tomaso (2012-05-31)
    I discuss the "levels of understanding" framework described in Marr's Vision and propose a revised and updated version of it to capture the changes in computation and neuroscience over the last 30 years.
  • Beal, Jacob (2003-03-17)
    In a Communication Bootstrapping system, peer components with different perceptual worlds invent symbols and syntax based on correlations between their percepts. I propose that Communication Bootstrapping can also be ...
  • Nahnsen, Thade; Uzuner, Ozlem; Katz, Boris (2005-05-19)
    We present a system to determine content similarity of documents. More specifically, our goal is to identify book chapters that are translations of the same original chapter; this task requires identification of not only ...
  • Dorr, Bonnie J. (1988-01-01)
    Current approaches to generation for machine translation make use of direct-replacement templates, large grammars, and knowledge-based inferencing techniques. Not only are rules language-specific, but they are too ...
  • Dorr, Bonnie J. (1989-06-01)
    This report introduces an implemented scheme for generating target- language sentences using a compositional representation of meaning called lexical conceptual structure. Lexical conceptual structure facilitates two crucial ...
  • Lee, John J. (2008-04-07)
    LIBPMK is a C++ implementation of Grauman and Darrell's pyramid match algorithm. This toolkit provides a flexible framework with which developers can quickly match sets of image features and run experiments. LIBPMK provides ...
  • Shim, Keun Sup; Cho, Myong Hyon; Lis, Mieszko; Khan, Omer; Devadas, Srinivas (2011-05-02)
    Directory-based cache coherence is a popular mechanism for chip multiprocessors and multicores. The directory protocol, however, requires multicast for invalidation messages and the collection of acknowledgement messages, ...
  • Sobalvarro, Patrick (1988-02-01)
    Garbage collector performance in LISP systems on custom hardware has been substantially improved by the adoption of lifetime-based garbage collection techniques. To date, however, successful lifetime-based garbage ...
  • McAllester, David; Siskind, Jeffrey (1991-12-01)
    Lifting is a well known technique in resolution theorem proving, logic programming, and term rewriting. In this paper we formulate lifting as an efficiency-motivated program transformation applicable to a wide variety ...
  • Christoudias, Chris Mario; Morency, Louis-Philippe; Darrell, Trevor (2003-04-18)
    Statistical shape and texture appearance models are powerful image representations, but previously had been restricted to 2D or simple 3D shapes. In this paper we present a novel 3D morphable model based on image-based ...
  • Richards, W.A. (1981-08-01)
    A lightness scale is derived from a theoretical estimate of the probability distribution of image intensities for natural scenes. The derived image intensity distribution considers three factors: reflectance, surface ...
  • Forbus, K. (1977-05-01)
    The perception of surface luster in achromatic single view images seems to depend on the existence of regions with source-like properties. These regions are due to the interaction of specular component of the surface's ...
  • Moore, David; Olson, Edwin; Huang, Albert (2009-09-02)
    We describe the Lightweight Communications and Marshalling (LCM) library for message passing and data marshalling. The primary goal of LCM is to simplify the development of low-latency message passing systems, targeted at ...
  • Chockler, Gregory; Malkhi, Dahlia (2004-04-22)
    We propose light-weight lease primitives to leverage fault-tolerant coordination among clients accessing a shared storage infrastructure (such as network attached disks or storage servers). In our approach, leases are ...
