    • Bagging Regularizes 

      Poggio, Tomaso; Rifkin, Ryan; Mukherjee, Sayan; Rakhlin, Alex (2002-03-01)
      Intuitively, we expect that averaging --- or bagging --- different regressors with low correlation should smooth their behavior and be somewhat similar to regularization. In this note we make this intuition precise. ...
    • Bandpass Channels, Zero-Crossings, and Early Visual Information Processing 

      Marr, D.; Poggio, T.; Ullman, S. (1978-09-01)
      A recent advance by B.F. Logan in the theory of one octave bandpass signals may throw new light on spatial-frequency-tuned channels in early visual information processing.
    • Basic Solid Mechanics for Tactile Sensing 

      Fearing, Ronald S.; Hollerbach, John M. (1984-03-01)
      In order to stably grasp objects without using object models, tactile feedback from the fingers is sometimes necessary. This feedback can be used to adjust grasping forces to prevent a part form slipping from a hand. ...
    • A Basis for a Mathematical Theory of Computation 

      McCarthy, John (1962-01-01)
      This paper is a corrected version of the paper of the same title given at the Western Joint Computer Conference, May 1961. A tenth section discussing the relations between mathematical logic and computation has been added. ...
    • Battling Reality 

      Flynn, Anita M.; Brooks, Rodney A. (1989-10-01)
      In the four years that the MIT Mobile Robot Project has benn in existence, we have built ten robots that focus research in various areas concerned with building intelligent systems. Towards this end, we have embarked on ...
    • The Behavior Language; User's Guide 

      Brooks, Rodney A. (1990-04-01)
      The Behavior Language is a rule-based real-time parallel robot programming language originally based on ideas from [Brooks 86], [Connell 89], and [Maes 89]. It compiles into a modified and extended version of the ...
    • A Behavior-Based Arm Controller 

      Connell, Jonathan H. (1988-06-01)
      In this paper we describe a working, implemented controller for a real, physical mobile robot arm. The controller is composed of a collection of 15 independent behaviors which run, in real time, on a set of 8 loosely coupled ...
    • Belief Propagation and Revision in Networks with Loops 

      Weiss, Yair (1997-11-01)
      Local belief propagation rules of the sort proposed by Pearl(1988) are guaranteed to converge to the optimal beliefs for singly connected networks. Recently, a number of researchers have empirically demonstrated good ...
    • The Bifurcation Interpreter: A Step Towards the Automatic Analysis of Dynamical Systems 

      Abelson, Harold (1989-09-01)
      The Bifurcation Interpreter is a computer program that autonomously explores the steady-state orbits of one-parameter families of periodically- driven oscillators. To report its findings, the Interpreter generates ...
    • The Binford-Horn LINE-FINDER 

      Horn, Berthold K.P. (1973-12-01)
      This paper briefly describes the processing performed in the course of producing a line drawing from an image obtained through an image dissector camera. The edge-marking pahse uses a non-linear parallel line-follower. ...
    • Binocular Shading and Visual Surface Reconstruction 

      Grimson, W.E.L. (1982-08-01)
      Zero-crossing or feature-point based stereo algorithms can, by definition, determine explicit depth information only at particular points on the image. To compute a complete surface description, this sparse depth map ...
    • A Binocular, Foveated Active Vision System 

      Scassellati, Brian (1998-03-01)
      This report documents the design and implementation of a binocular, foveated active vision system as part of the Cog project at the MIT Artificial Intelligence Laboratory. The active vision system features a three degree ...
    • Biologically Plausible Neural Circuits for Realization of Maximum Operations 

      Yu, Angela J.; Giese, Martin A.; Poggio, Tomaso A. (2001-09-01)
      Object recognition in the visual cortex is based on a hierarchical architecture, in which specialized brain regions along the ventral pathway extract object features of increasing levels of complexity, accompanied by greater ...
    • Biologically Plausible Neural Model for the Recognition of Biological Motion and Actions 

      Giese, Martin Alexander; Poggio, Tomaso (2002-08-01)
      The visual recognition of complex movements and actions is crucial for communication and survival in many species. Remarkable sensitivity and robustness of biological motion perception have been demonstrated in ...
    • Biophysics of Computation: Neurons, Synapses and Membranes 

      Koch, Christof; Poggio, Tomaso (1984-10-01)
      Synapses, membranes and neurotransmitters play an important role in processing information in the nervous system. We do not know, however, what biophysical mechanisms are critical for neuronal computations, what ...
    • Boltzmannn Weighted Selection Improves Performance of Genetic Algorithms 

      de la Maza, Michael; Tidor, Bruce (1991-12-01)
      Modifiable Boltzmann selective pressure is investigated as a tool to control variability in optimizations using genetic algorithms. An implementation of variable selective pressure, modeled after the use of temperature ...
    • Boolean Classes 

      McAllester, David; Zabih, Ramin (1986-09-01)
      Object-oriented programming languages all involve the notions of class and object. We extend the notion of class so that any Boolean combination of classes is also a class. Boolean classes allow greater precision and ...
    • Boosting Image Database Retrieval 

      Tieu, Kinh; Viola, Paul (1999-09-10)
      We present an approach for image database retrieval using a very large number of highly-selective features and simple on-line learning. Our approach is predicated on the assumption that each image is generated by a ...
