  • Basis Token Consistency: A Practical Mechanism for Strong Web Cache Consistency
    Bradley, Adam D.; Bestavros, Azer (Boston University Computer Science Department, 2001-10-30)
    With web caching and cache-related services like CDNs and edge services playing an increasingly significant role in the modern internet, the problem of the weak consistency and coherence provisions in current web protocols ...
  • Basket Cases and Breadbaskets: Sacred Rice and Agricultural Development in Postcolonial Africa
    Davidson, Joanna (Wiley, 2012)
    Based on ethnographic research among rural Diola in Guinea-Bissau, I provide a broad view of the history and interpenetration of rice in social, political, religious, and ecological domains, while chronicling the current ...
  • A Bayesian Approach for TCP to Distinguish Congestion from Wireless Losses
    Barman, Dhiman; Matta, Ibrahim (Boston University Computer Science Department, 2003-12-03)
    (This Technical Report revises TR-BUCS-2003-011) The Transmission Control Protocol (TCP) has been the protocol of choice for many Internet applications requiring reliable connections. The design of TCP has been challenged ...
  • Bayesian Packet Loss Detection for TCP
    Fonseca, Nahur; Crovella, Mark (Boston University Computer Science Department, 2004-07-06)
    One of TCP's critical tasks is to determine which packets are lost in the network, as a basis for control actions (flow control and packet retransmission). Modern TCP implementations use two mechanisms: timeout, and fast ...
  • Benefits of Stimulus Congruency for Multisensory Facilitation of Visual Learning
    Kim, Robyn S.; Seitz, Aaron R.; Shams, Ladan (Public Library of Science, 2008-1-30)
    BACKGROUND. Studies of perceptual learning have largely focused on unisensory stimuli. However, multisensory interactions are ubiquitous in perception, even at early processing stages, and thus can potentially play a role ...
  • Beta Oscillations and Hippocampal Place Cell Learning during Exploration of Novel Environments
    Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2008-07-29)
    Berke et al. (2008) reported that beta oscillations occur during the learning of hippocampal place cell receptive fields in novel environments. Place cell selectivity can develop within seconds to minutes, and can remain ...
  • Beta-Reduction As Unification
    Kfoury, A.J. (Boston University Computer Science Department, 1996-07-08)
    We define a unification problem ^UP with the property that, given a pure lambda-term M, we can derive an instance Gamma(M) of ^UP from M such that Gamma(M) has a solution if and only if M is beta-strongly normalizable. ...
  • Beyond Charity: The Rights-Based Approach in Theory and Practice
    Hunter, Sarah (2012-07-05)
  • Biased ART: A Neural Architecture that Shifts Attention Toward Previously Disregarded Features Following an Incorrect Prediction
    Carpenter, Gail A.; Gaddam, Sai Chaitanya (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2009-04)
    Memories in Adaptive Resonance Theory (ART) networks are based on matched patterns that focus attention on those portions of bottom-up inputs that match active top-down expectations. While this learning strategy has proved ...
  • Binaural Cues for Distance and Direction of Nearby Sound Sources
    Shinn-Cunningham, Barbara; Santarelli, Scott; Kopco, Norbert (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1999-10)
    To a first-order approximation, binaural localization cues are ambiguous: a number of source locations give rise to nearly the same interaural differences. For sources more than a meter from the listener, binaural localization ...
  • Binding of Object Representations by Synchronous Cortical Dynamics Explains Temporal Order and Spatial Pooling Data
    Gruenwald, Alexander; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1994-05)
    A key problem in cognitive science concerns how the brain binds together parts of an object into a coherent visual object representation. One difficulty that this binding process needs to overcome is that different parts ...
  • Biological Context Networks: A Mosaic View of the Interactome
    Rachlin, John; Cohen, Dikla Dotan; Cantor, Charles; Kasif, Simon (2006-11-28)
    Network models are a fundamental tool for the visualization and analysis of molecular interactions occurring in biological systems. While broadly illuminating the molecular machinery of the cell, graphical representations ...
  • Biologically Inspired Approaches to Automated Feature Extraction and Target Recognition
    Carpenter, Gail; Martens, Siegfried; Mingolla, Ennio; Ogas, Ogi; Sai, Chaitanya (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 2004-10)
    Ongoing research at Boston University has produced computational models of biological vision and learning that embody a growing corpus of scientific data and predictions. Vision models perform long-range grouping and ...
  • A Biomechanical Model of Human Oculomotor Plant Kinematics Based Upon Geometric Algebra
    Cohen, Michael A.; Pribe, Christopher A. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-06)
    A biomechanical model of the human oculomotor plant kinematics in 3-D as a function of muscle length changes is presented. It can represent a range of alternative interpretations of the data as a function of one parameter. ...
  • Birth of a Learning Law
    Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1997-10)
  • Blocking Java Applets at the Firewall
    Martin, David M.; Rajagopalan, Sivaramakrishnan; Rubin, Aviel D. (Boston University Computer Science Department, 1996-10-29)
    This paper explores the problem of protecting a site on the Internet against hostile external Java applets while allowing trusted internal applets to run. With careful implementation, a site can be made resistant to current ...
  • Book Review: Unequal Partnerships: Beyond the Rhetoric of Philanthropic Collaboration. By Ira Silver
    Barman, Emily (American Journal of Sociology, 2006-11)
  • Boosting Nearest Neighbor Classifiers for Multiclass Recognition
    Athitsos, Vassilis; Sclaroff, Stan (Boston University Computer Science Department, 2004-02-13)
    This paper introduces an algorithm that uses boosting to learn a distance measure for multiclass k-nearest neighbor classification. Given a family of distance measures as input, AdaBoost is used to learn a weighted distance ...
  • BoostMap: A Method for Efficient Approximate Similarity Rankings
    Athitsos, Vassilis; Alon, Jonathan; Sclaroff, Stan; Kollios, George (Boston University Computer Science Department, 2003-11-24)
    This paper introduces BoostMap, a method that can significantly reduce retrieval time in image and video database systems that employ computationally expensive distance measures, metric or non-metric. Database and query ...
