  • Taylor, Michael Bedford (2004-06-07)
    In this paper, we introduce the concept of a deionizer. A deionizeris a special type of partial evaluator whose purpose is to create a newversion of a program that can run without accessing a partial set of I/O resources.Although ...
  • Vandiver, Benjamin Mead (2008-06-30)
    This thesis describes the design, implementation, and evaluation of a replication scheme to handle Byzantine faults in transaction processing database systems. The scheme compares answers from queries and updates on multiple ...
  • Bose, Biswajit; Wang, Xiaogang; Grimson, Eric (2006-04-25)
    We propose a framework for detecting and tracking multiple interacting objects from a single, static, uncalibrated camera. The number of objects is variable and unknown, and object-class-specific models are not available. ...
  • Hug, Caleb (2009-08-26)
    The modern intensive care unit (ICU) has become a complex, expensive, data-intensive environment. Caregivers maintain an overall assessment of their patients based on important observations and trends. If an advanced ...
  • Kondacs, Attila (2005-01-28)
    In this thesis I will be concerned with linking the observed speechsignal to the configuration of articulators.Due to the potentially rapid motion of the articulators, the speechsignal can be highly non-stationary. The ...
  • Beal, Jacob (2007-05-15)
    We can evaluate models of natural intelligence, as well as theirindividual components, by using a model of hardware and developmentcosts, ignoring almost all the details of biology. The basic argumentis that neither the ...
  • Shimizu, Hiroaki; Poggio, Tomaso (2003-08-27)
    The capability of estimating the walking direction of people would be useful in many applications such as those involving autonomous cars and robots.We introduce an approach for estimating the walking direction of people ...
  • Kemp, Charles; Griffiths, Thomas L.; Tenenbaum, Joshua B. (2004-07-22)
    We present a framework for learning abstract relational knowledge with the aimof explaining how people acquire intuitive theories of physical, biological, orsocial systems. Our approach is based on a generative relational ...
  • Sivic, Josef; Russell, Bryan C.; Efros, Alexei A.; Zisserman, Andrew; Freeman, William T. (2005-02-25)
    Given a set of images containing multiple object categories,we seek to discover those categories and their image locations withoutsupervision. We achieve this using generative modelsfrom the statistical text literature: ...
  • Urtasun, Raquel; Darrell, Trevor (2007-03-28)
    Supervised learning is difficult with high dimensional input spacesand very small training sets, but accurate classification may bepossible if the data lie on a low-dimensional manifold. GaussianProcess Latent Variable ...
  • Balas, Benjamin J.; Sinha, Pawan (2003-08-13)
    A fundamental question in visual neuroscience is how to represent image structure. The most common representational schemes rely on differential operators that compare adjacent image regions. While well-suited to encoding ...
  • Tzanov, Velin K. (2006-12-05)
    The main goal of this thesis is to demonstrate the applicability of the distributed systems paradigm to robotic systems. This goal is accomplished by presenting two solutions to the Distributed Area Search problem: organizing ...
  • 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 ...
