  • Qumsiyeh, Dany M. (2008-07-14)
    This thesis investigates the feasibility of a smart building evacuation system, capable of guiding occupants along safe paths to exits and responding to changing threats. Inspired by developments in amorphous computing, ...
  • Oshman, Rotem; Lynch, Nancy; Kuhn, Fabian (2009-11-10)
    In this report we investigate distributed computation in dynamic networks in which the network topology changes from round to round. We consider a worst-case model in which the communication links for each round are chosen ...
  • Block, Stephen (2007-03-05)
    Many applications of autonomous agents require groups to work in tight coordination. To be dependable, these groups must plan, carry out and adapt their activities in a way that is robust to failure and to uncertainty. ...
  • Panchekha, Pavel; Brodsky, Micah (2013-10-08)
    Shared mutable state is challenging to maintain in a distributed environment. We develop a technique, based on the Operational Transform, that guides independent agents into producing consistent states through inconsistent ...
  • Uzuner, Ozlem (2004-07-25)
    In this paper, we discuss a wireless grid in which users are highly mobile, and form ad-hoc and sometimes short-lived connections with other devices. As they roam through networks, the users may choose to employ ...
  • Perez-Breva, Luis; Ortiz, Luis E.; Yeang, Chen-Hsiang, 1969-; Jaakkola, Tommi (2006-03-06)
    We propose a game-theoretic approach tolearn and predict coordinate binding of multiple DNA bindingregulators. The framework implements resource constrainedallocation of proteins to local neighborhoods as well as to ...
  • Poggio, Tomaso; Mutch, Jim; Anselmi, Fabio; Tacchetti, Andrea; Rosasco, Lorenzo; Leibo, Joel Z. (2013-08-06)
    Tuning properties of simple cells in cortical V1 can be described in terms of a "universal shape" characterized by parameter values which hold across different species. This puzzling set of findings begs for a general ...
  • Sun, Chen; Chen, Chia-Hsin Owen; Kurian, George; Wei, Lan; Miller, Jason; Agarwal, Anant; Peh, Li-Shiuan; Stojanovic, Vladimir (2012-02-08)
    With the advent of many-core chips that place substantial demand on the NoC, photonics has been investigated as a promising alternative to electrical NoCs. While numerous opto-electronic NoCs have been proposed, their ...
  • Heo, Seongmoo; Asanovic, Krste (2004-07-12)
    Digital circuits often have a critical path that runs through a smallsubset of the component subblocks, but where the path changes dynamicallyduring operation. Dynamically resizable static CMOS (DRCMOS) logic isproposed ...
  • Attie, Paul C.; Lynch, Nancy A. (2013-07-08)
    We present dynamic I/O automata (DIOA), a compositional model of dynamic systems, based on I/O automata. In our model, automata can be created and destroyed dynamically, as computation proceeds. In addition, an automaton ...
  • Attie, Paul C.; Lynch, Nancy A. (2003-07-26)
    We present a mathematical state-machine model, the Dynamic I/O Automaton (DIOA) model, for defining and analyzing dynamic systems of interacting components. The systems we consider are dynamic in two senses: (1) components ...
  • Sezgin, Tevfik Metin; Davis, Randall (2004-07-28)
    Freehand sketching is a natural and crucial part of everyday humaninteraction, yet is almost totally unsupported by current user interfaces. With the increasing availability of tablet notebooks and pen based PDAs, sketchbased ...
  • Pacheo, Carlos; Ernst, Michael D. (2004-10-14)
    This paper describes a technique that helps a test engineerselect, from a large set of randomly generated testinputs, a small subset likely to reveal faults in the softwareunder test. The technique takes a program or ...
  • Psota, James; Agarwal, Anant; Miller, Jason; Beckmann, Nathan; Kurian, George (2010-02-11)
    Ever since industry has turned to parallelism instead of frequency scaling to improve processor performance, multicore processors have continued to scale to larger and larger numbers of cores. Some believe that multicores ...
  • Grauman, Kristen; Darrell, Trevor (2004-11-22)
    Sets of local features that are invariant to common image transformations are an effective representation to use when comparing images; current methods typically judge feature sets' similarity via a voting scheme (which ...
  • Salakhutdinov, Ruslan; Hinton, Geoffrey (2010-08-04)
    We present a new learning algorithm for Boltzmann Machines that contain many layers of hidden variables. Data-dependent statistics are estimated using a variational approximation that tends to focus on a single mode, and ...
  • Levin, Anat; Weiss, Yair; Durand, Fredo; Freeman, William T. (2011-04-04)
    In blind deconvolution one aims to estimate from an input blurred image y a sharp image x and an unknown blur kernel k. Recent research shows that a key to success is to consider the overall shape of the posterior distribution ...
  • Ono, Masahiro; Williams, Brian C. (2008-03-06)
    When controlling dynamic systems such as mobile robots in uncertain environments, there is a trade off between risk and reward. For example, a race car can turn a corner faster by taking a more challenging path. This paper ...
  • Lee, John J. (2008-05-06)
    Algorithms for recognition and retrieval tasks generally call for both speed and accuracy. When scaling up to very large applications, however, we encounter additional significant requirements: adaptability and scalability. ...
  • Roy, Nicholas; He, Ruijie (2009-09-23)
    Online, forward-search techniques have demonstrated promising results for solving problems in partially observable environments. These techniques depend on the ability to efficiently search and evaluate the set of beliefs ...
