  • Heikkinen, Mikko V. J.; Berger, Arthur W. (2011-05-03)
    We compare Web traffic characteristics of mobile- versus fixed-access end-hosts, where herein the term "mobile" refers to access via cell towers, using for example the 3G/UMTS standard, and the term "fixed" includes Wi-Fi ...
  • Abbott, Tim; Kane, Daniel; Valiant, Paul (2005-02-08)
    We exhibit a polynomial reduction from the problem of finding a Nashequilibrium of a bimatrix game with rational coefficients to the problemof finding a Nash equilibrium of a bimatrix game with 0-1 coefficients.
  • Morgenstern, Christian; Heisele, Bernd (2003-11-28)
    We present a component-based approach for recognizing objectsunder large pose changes. From a set of training images of a givenobject we extract a large number of components which are clusteredbased on the similarity of ...
  • Bonawitz, Keith A (2008-07-23)
    Probabilistic inference provides a unified, systematic framework for specifying and solving these problems. Recent work has demonstrated the great value of probabilistic models defined over complex, structured domains. ...
  • Wingate, David; Diuk, Carlos; O'Donnell, Timothy; Tenenbaum, Joshua; Gershman, Samuel (2013-04-12)
    This paper describes a probabilistic framework for incorporating structured inductive biases into reinforcement learning. These inductive biases arise from policy priors, probability distributions over optimal policies. ...
  • Poggio, Tomaso; Mutch, Jim; Leibo, Joel; Rosasco, Lorenzo; Tacchetti, Andrea (2012-12-29)
    This paper explores the theoretical consequences of a simple assumption: the computational goal of the feedforward path in the ventral stream -- from V1, V2, V4 and to IT -- is to discount image transformations, after ...
  • Agarwala, Aseem; Bae, Soonmin; Durand, Fredo (2010-04-07)
    Rephotographers aim to recapture an existing photograph from the same viewpoint. A historical photograph paired with a well-aligned modern rephotograph can serve as a remarkable visualization of the passage of time. However, ...
  • Gardiol, Natalia H.; Kaelbling, Leslie Pack (2006-03-20)
    In order for autonomous artificial decision-makers to solverealistic tasks, they need to deal with the dual problems of searching throughlarge state and action spaces under time pressure.We study the problem of planning ...
  • Zhou, You (2009-04-16)
    Network coordinate systems allow for efficient construction of large-scale distributed systems on the Internet. Coordinates provide locality information in a compact way, without requiring each node to contact every potential ...
  • Jackson, Daniel (2013-08-08)
    A research agenda in software design is outlined, focusing on the role of concepts. The notions of concepts as "abstract affordances" and of conceptual integrity are discussed, and a series of small examples of conceptual ...
  • Taycher, Leonid; Shakhnarovich, Gregory; Demirdjian, David; Darrell, Trevor (2005-12-01)
    We describe a state-space tracking approach based on a Conditional Random Field(CRF) model, where the observation potentials are \emph{learned} from data. Wefind functions that embed both state and observation into a space ...
  • Lynch, Nancy; Sastry, Srikanth (2015-03-02)
    The FLP result shows that crash-tolerant consensus is impossible to solve in asynchronous systems, and several solutions have been proposed for crash-tolerant consensus under alternative (stronger) models. One popular ...
  • Azar, Pablo; Chen, Jing; Micali, Silvio (2010-12-20)
    Classical Bayesian mechanism design is "centralized," that is, the designer is assumed to know the distribution D from which the players' type profile has been drawn. We instead investigate a very "decentralized" Bayesian ...
  • Azar, Pablo; Chen, Jing; Micali, Silvio (2010-09-08)
    We put forward a new class of mechanisms. In this extended abstract, we exemplify our approach only for single-good auctions in what we call a conservative-Bayesian setting. (Essentially, no common-knowledge about the ...
  • Chen, Jing; Micali, Silvio (2010-12-20)
    In mechanism design, the traditional way of modeling the players' incomplete information about their opponents is "assuming a Bayesian." This assumption, however, is very strong and does not hold in many real applications. ...
  • Beal, Jacob; Bachrach, Jonathan; Tobenkin, Mark (2007-08-24)
    Long-lived sensor network applications must be able to self-repair and adapt to changing demands. We introduce a new approach for doing so: Constraint and Restoring Force. CRF is a physics-inspired framework for computing ...
  • Rose, Eva (2014-10-01)
    Our goal is to present a completed, semantic formalization of the Jeeves privacy language evaluation engine, based on the original Jeeves constraint semantics defined by Yang et al at POPL12, but sufficiently strong to ...
  • Werfel, Justin; Bar-Yam, Yaneer; Nagpal, Radhika (2005-04-08)
    We describe a system in which simple, identical, autonomous robots assemble two-dimensional structures out of identical building blocks. We show that, in a system divided in this way into mobile units and structural units, ...
  • Morency, Louis-Philippe (2006-11-15)
    During face-to-face conversation, people use visual feedback (e.g.,head and eye gesture) to communicate relevant information and tosynchronize rhythm between participants. When recognizing visualfeedback, people often rely ...
  • Torralba, Antonio (2004-04-14)
    This article describes a model for including scene/context priors in attention guidance. In the proposed scheme, visual context information can be available early in the visual processing chain, in order to modulate the ...
