  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    This article applies a recent theory of 3-D biological vision, called FACADE Theory, to explain several percepts which Kanizsa pioneered. These include 3-D pop-out of an occluding form in front of an occluded form, leading ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1995-05)
    When humans gaze upon a scene, our brains rapidly combine several different types of locally ambiguous visual information to generate a globally consistent and unambiguous representation of Form-And-Color-And-DEpth, or ...
  • Fenner, S.; Green, F.; Homer, S.; Zhang, Y. (Boston University Computer Science Department, 2004-01-12)
    We show that if a language is recognized within certain error bounds by constant-depth quantum circuits over a finite family of gates, then it is computable in (classical) polynomial time. In particular, our results imply ...
  • Grossberg, Stephen; Carpenter, Gail; Ersoy, Bilgin (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2005-01)
    How do humans and animals learn to recognize objects and events? Two classical views are that exemplars or prototypes are learned. A hybrid view is that a mixture, called rule-plus-exceptions, is learned. None of these ...
  • Przybyszewski, Andrezej; Pollen, Daniel (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2000-06)
    Feedback from the visual cortex (Vl) to the Lateral Geniculate Nucleus (LGN) in macaque monkey increase contrast gain of LGN neurons for black and white (B&W) and for color (C) stimuli. LGN parvocellular cells responses ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-07)
  • Grossberg, Stephen; Markowitz, Jeffrey; Cao, Yongqiang (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2009-06-22)
    Anterior inferotemporal cortex (ITa) plays a key role in visual object recognition. Recognition is tolerant to object position, size, and view changes, yet recent neurophysiological data show ITa cells with high object ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-01)
    The processes whereby our brains continue to learn about a changing world in a stable fashion throughout life are proposed to lead to conscious experiences. These processes include the learning of top-down expectations, ...
  • Gove, Alan; Grossberg, Stephen; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-11)
    A neural network model is developed to explain how visual thalamocortical interactions give rise to boundary percepts such as illusory contours and surface percepts such as filled-in brightnesses. Top-down feedback ...
  • Gove, Alan; Grossberg, Stephen; Mingolla, Ennio (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    A neural network model of early visual processing offers an explanation of brightness effects often associated with illusory contours. Top-down feedback from the model's analog of visual cortical complex cells to model ...
  • Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2003-02)
    ACT is compared with a particular type of connectionist model that cannot handle symbols and use non-biological operations that cannot learn in real time. This focus continues an unfortunate trend of straw man "debates" ...
  • Medina, Alberto; Matta, Ibrahim; Byers, John (Boston University Computer Science Department, 2000-01-21)
    BRITE is a parametrized topology generation tool, which can be used to flexibly control various parameters (such as connectivity and growth models) and study various properties of generated topologies (such power laws, ...
  • Medina, Alberto; Lakhina, Anukool; Matta, Ibrahim; Byers, John (Boston University Computer Science Department, 2001-04-12)
    Effective engineering of the Internet is predicated upon a detailed understanding of issues such as the large-scale structure of its underlying physical topology, the manner in which it evolves over time, and the way in ...
  • Kahn, Michael I.; Golen, James A.; Rheingold, Arnold L.; Doerrer, Linda H. (International Union of Crystallography, 2009-8-26)
    The crystal structure of the title compound, [PtBr(C15H11N3)][AuBr2]·(CH3)2SO, exhibits infinite chains of {PtAuPt}∞ metallophilic interactions along the b axis. Two cations and one anion stack in a trimer with a unique ...
  • Bradley, Adam (Boston University Computer Science Department, 1999-09-07)
    In a recent paper (Changes in Web Client Access Patterns: Characteristics and Caching Implications by Barford, Bestavros, Bradley, and Crovella) we performed a variety of analyses upon user traces collected in the Boston ...
  • Grossberg, Stephen; Rubin, Mark A.; Streilein, William W. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1996-05)
    Fuzzy ARTMAP has to date been applied to a variety of automatic target recognition tasks, including radar range profile classification. In simulations of this task, it has demonstrated significant compression compared to ...
  • Campos, Marcos M.; Carpenter, Gail A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-01)
    This paper introduces CSOM, a continuous version of the Self-Organizing Map (SOM). The CSOM network generates maps similar to those created with the original SOM algorithm but, due to the continuous nature of the mapping, ...
  • Campos, Marcos; Carpenter, Gail A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1998-06)
    This paper introduces CSOM, a distributed version of the Self-Organizing Map network capable of generating maps similar to those created with the original algorithm. Due to the continuous nature of the mapping, CSOM ...
  • Unknown author (Boston University Computer Science Department, 1993-10)
    Predictability - the ability to foretell that an implementation will not violate a set of specified reliability and timeliness requirements - is a crucial, highly desirable property of responsive embedded systems. This ...
