    • Determining articulator configuration in voiced stop consonants by matching time-domain patterns in pitch periods 

      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 ...
    • Developmental Cost for Models of Intelligence 

      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 ...
    • Direction Estimation of Pedestrian from Images 

      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 ...
    • Discovering Latent Classes in Relational Data 

      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 ...
    • Discovering object categories in image collections 

      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: ...
    • Discriminative Gaussian Process Latent Variable Model for Classification 

      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 ...
    • Dissociated Dipoles: Image representation via non-local comparisons 

      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 ...
    • Distributed Area Search with a Team of Robots 

      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 ...
    • A Distributed Building Evacuation System 

      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, ...
    • Distributed Computation in Dynamic Networks 

      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 ...
    • Distributed Method Selection and Dispatching of Contingent, Temporally Flexible Plans 

      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. ...
    • Distributed Shared State with History Maintenance 

      Panchekha, Pavel; Brodsky, Micah Z. (Micah Zev) (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 ...
    • Distribution Volume Tracking on Privacy-Enhanced Wireless Grid 

      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 ...
    • DNA Binding and Games 

      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 ...
    • Does invariant recognition predict tuning of neurons in sensory cortex? 

      Poggio, Tomaso; Mutch, Jim; Anselmi, Fabio; Tacchetti, Andrea; Rosasco, Lorenzo; e.a. (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 ...
