  • Efficient Nearest Neighbor Classification Using a Cascade of Approximate Similarity Measures
    Athitsos, Vassilis; Alon, Jonathan; Sclaroff, Stan (Boston University Computer Science Department, 2005-03-16)
    Nearest neighbor classification using shape context can yield highly accurate results in a number of recognition problems. Unfortunately, the approach can be too slow for practical applications, and thus approximation ...
  • Efficient Support for Common Relations in Lightweight Formal Reasoning Systems
    Lapets, Andrei; House, DAvid (Boston University Computer Science Department, 2009-11-06)
    In work that involves mathematical rigor, there are numerous benefits to adopting a representation of models and arguments that can be supplied to a formal reasoning or verification system: reusability, automatic evaluation ...
  • An Efficient User-Level Shared Memory Mechanism for Application-Specific Extensions
    West, Richard; Gloudon, Jason; Qi, Xin; Parmer, Gabriel; Gloudon, Jason (Boston University Computer Science Department, 2005-02-23)
    This paper focuses on an efficient user-level method for the deployment of application-specific extensions, using commodity operating systems and hardware. A sandboxing technique is described that supports multiple extensions ...
  • The EGOIST Overlay Routing System
    Smaragdakis, Georgios; Lekakis, Vassilis; Laoutaris, Nikolaos; Bestavros, Azer; Byers, John W.; Roussopoulos, Mema (Boston University Computer Science Department, 2008-07-01)
    A foundational issue underlying many overlay network applications ranging from routing to peer-to-peer file sharing is that of connectivity management, i.e., folding new arrivals into an existing overlay, and rewiring to ...
  • EGOIST: Overlay Routing Using Selfish Neighbor Selection
    Smaragdakis, Georgios; Laoutaris, Nikolaos; Bestavros, Azer; Byers, John W.; Roussopoulos, Mema (Boston University Computer Science Department, 2007)
    A foundational issue underlying many overlay network applications ranging from routing to P2P file sharing is that of connectivity management, i.e., folding new arrivals into an existing overlay, and re-wiring to cope with ...
  • The Elegiac Puella as Virgin Martyr
    Uden, James (The Johns Hopkins University Press, 2009)
    This paper explores the ideological currents running through Maximianus's subversive revival of the genre of Augustan love elegy in the beleaguered Rome of the mid-sixth century. The third elegy narrates an apparent childhood ...
  • Eliminating Redundant Training Data Using Unsupervised Clustering Techniques
    Gonsalves, Paul G.; Snorrason, Magnus; Caglayan, Alper K. (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1993-01)
    Training data for supervised learning neural networks can be clustered such that the input/output pairs in each cluster are redundant. Redundant training data can adversely affect training time. In this paper we apply two ...
  • Embedding Games
    Londono, Jorge (CS Department, Boston University, 2010-07-20)
    Large scale distributed computing infrastructures pose challenging resource management problems, which could be addressed by adopting one of two perspectives. On the one hand, the problem could be framed as a global ...
  • Emergence of Tri-Phasic Muscle Activation from the Non-linear Interactions of Central and Spinal Neural Network Circuits
    Bullock, Dan; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1991-02)
    The origin of the tri-phasic burst pattern, observed in the EMGs of opponent muscles during rapid self-terminated movements, has been controversial. Here we show by computer simulation that the pattern emerges from ...
  • Endocrine Activity of Extraembryonic Membranes Extends beyond Placental Amniotes
    Albergotti, Lori C.; Hamlin, Heather J.; McCoy, Michael W.; Guillette,, Louis J. (Public Library of Science, 2009-5-8)
    BACKGROUND. During development, all amniotes (mammals, reptiles, and birds) form extraembryonic membranes, which regulate gas and water exchange, remove metabolic wastes, provide shock absorption, and transfer maternally ...
  • End-to-End Inference of Loss Nature in a Hybrid Wired/Wireless Environment
    Liu, Jun; Matta, Ibrahim; Crovella, Mark (Boston University Computer Science Department, 2002-03-14)
    End-to-End differentiation between wireless and congestion loss can equip TCP control so it operates effectively in a hybrid wired/wireless environment. Our approach integrates two techniques: packet loss pairs (PLP) and ...
  • An Energy-conscious Transport Protocol for Multi-hop Wireless Networks
    Riga, N.; Matta, I.; Medina, A.; Partridge, C.; Redi, J. (Boston University Computer Science Department, 2007)
    We present a transport protocol whose goal is to reduce power consumption without compromising delivery requirements of applications. To meet its goal of energy efficiency, our transport protocol (1) contains mechanisms ...
  • Entropy Loss is Maximal for Uniform Inputs
    Reyzin, Leonid (Boston University Computer Science Department, 2007-09-20)
    A secure sketch (defined by Dodis et al.) is an algorithm that on an input w produces an output s such that w can be reconstructed given its noisy version w' and s. Security is defined in terms of two parameters m and m˜ : ...
  • Environments that Induce Synthetic Microbial Ecosystems
    Klitgord, Niels; Segrè, Daniel (Public Library of Science, 2010-11-18)
    Interactions between microbial species are sometimes mediated by the exchange of small molecules, secreted by one species and metabolized by another. Both one-way (commensal) and two-way (mutualistic) interactions may ...
  • Equational Axiomization of Bicoercibility for Polymorphic Types
    Tiuryn, Jerzy (Boston University Computer Science Department, 1995-02)
    Two polymorphic types σ and τ are said to be bicoercible if there is a coercion from σ to τ and conversely. We give a complete equational axiomatization of bicoercible types and prove that the relation of bicoercibility ...
  • Equilibria and Dynamics of a Neural Network Model for Opponent Muscle Control
    Bullock, Daniel; Contreras-Vidal, José L.; Grossberg, Stephen (Boston University Center for Adaptive Systems and Department of Cognitive and Neural Systems, 1992-02)
    One of the advantages of biological skeleto-motor systems is the opponent muscle design, which in principle makes it possible to achieve facile independent control of joint angle and joint stiffness. Prior analysis of ...
  • Ergodicity and Mixing Rate of One-Dimensional Cellular Automata
    Park, Kihong (Boston University Computer Science Department, 1996-07-22)
    One-and two-dimensional cellular automata which are known to be fault-tolerant are very complex. On the other hand, only very simple cellular automata have actually been proven to lack fault-tolerance, i.e., to be mixing. ...

    Rosales, Rómer; Siddiqui, Matheen; Alon, Jonathan; Sclaroff, Stan (Boston University Computer Science Department, 2001-06)
    An approach for estimating 3D body pose from multiple, uncalibrated views is proposed. First, a mapping from image features to 2D body joint locations is computed using a statistical framework that yields a set of several ...
