  • Bradley, Elizabeth (1991-10-01)
    Control algorithms which exploit the unique properties of chaos can vastly improve the design and performance of many practical and useful systems. The program Perfect Moment is built around such an algorithm. Given ...
  • Bradley, Elizabeth (1991-03-01)
    This paper presents techniques that actively exploit chaotic behavior to accomplish otherwise-impossible control tasks. The state space is mapped by numerical integration at different system parameter values and ...
  • Raibert, Marc (1977-04-01)
    This is the second of a two part presentation of a model for motor control and learning. The model was implemented using a small computer and the MIT -Scheinman manipulator. Experiments were conducted which demonstrate ...
  • Lim, Kuk Huang (1981-02-01)
    The dynamics and control of tendon driven three degree of freedom shoulder joint are studied. A control scheme consisting of two phases has been developed. In the first phase, approximation of the time optimal control ...
  • Girosi, Federico; Anzellotti, Gabriele (1992-03-01)
    In this paper we consider the problem of approximating a function belonging to some funtion space Φ by a linear comination of n translates of a given function G. Ussing a lemma by Jones (1990) and Barron (1991) we show ...
  • Jordan, Michael I.; Xu, Lei (1993-11-01)
    The Expectation-Maximization (EM) algorithm is an iterative approach to maximum likelihood parameter estimation. Jordan and Jacobs (1993) recently proposed an EM algorithm for the mixture of experts architecture of ...

    Guzman, Adolfo; McIntosh, Harold (1966-06-01)
    A programming language is described which is applicable to problems conveniently described by transformation rules. By this we mean that patterns may be prescribed, each being associated with a skeleton, so that a series ...
  • Marr, D.; Poggio, T. (1976-06-01)
    The extraction of stereo disparity information from two images depends upon establishing a correspondence between them. This article analyzes the nature of the correspondence computation, and derives a cooperative algorithm ...
  • Poggio, M.; Poggio, T. (1995-04-11)
    We have simulated the behavior of several artificial flies, interacting visually with each other. Each fly is described by a simple tracking system (Poggio and Reichardt, 1973; Land and Collett, 1974) which summarizes ...
  • Lin, Kevin K. (1998-03-01)
    This project investigates the computational representation of differentiable manifolds, with the primary goal of solving partial differential equations using multiple coordinate systems on general n- dimensional spaces. ...
  • Flash, Tamar; Hogan, Neville (1984-11-01)
    This paper presents studies of the coordination f voluntary human arm movements. A mathematical model is formulated which is shown to predict both the qualitative features and the quantitative details observed ...
  • Hofstadter, Douglas (1984-01-01)
    A micro-world is described, in which many analogies involving strikingly different concepts and levels of subtlety can be made. The question "What differentiates the good ones from the bad ones?" is discussed, and ...
  • Levow, Gina-Anne (1998-05-27)
    The need for robust and easily extensible systems for word sense disambiguation coupled with successes in training systems for a variety of tasks using large on-line corpora has led to extensive research into corpus-based ...
  • Shashua, Amnon (1991-12-01)
    The paper presents a simple model for recovering affine shape and correspondence from two orthographic views of a 3D object. It is shown that four corresponding points along two orthographic views, taken under similar ...
  • Pitman, Kent M. (1985-02-01)
    This paper reports work in progress on an experimental text editor called CREF, the Cross Referenced Editing Facility. CREF deals with chunks of text, called segments, which may have associated features such as keywords ...
  • Bicchi, Antionio (1990-10-01)
    This paper deals with the design of multi-axis force (also known as force/torque) sensors, as considered within the framework of optimal design theory. The principal goal of this paper is to identify a mathematical ...
  • Hart, T. (1964-12-01)
    The LISP system (command version) has been updated. Bugs are corrected include: 1. out of pushdown list in compiled function will not transfer to 77777. 2. with compiler printing turned off by comprint, it is truly off. ...
  • Asada, Haruo; Brady, Michael (1984-02-01)
    In this paper we introduce a novel representation of the significant changes in curvature along the bounding contour of planar shape. We call the representation the curvature primal sketch. We describe an implemented ...
  • Subirana-Vilanova, J. Brian (1991-10-01)
    In this paper we present an approach to perceptual organization and attention based on Curved Inertia Frames (C.I.F.), a novel definition of "curved axis of inertia'' tolerant to noisy and spurious data. The definition ...
  • Horn, B.K.P. (1981-01-01)
    Here we search for the curve which has the smallest integral of the square of curvature, while passing through two given points with given orientation. This is the true shape of a spline used in lofting. In computer-aided ...
