Discriminative Gaussian Process Latent Variable Model for Classification
(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
(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
(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
(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
(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
(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
(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
(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
(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?
(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 ... -
DSENT - A Tool Connecting Emerging Photonics with Electronics for Opto-Electronic Networks-on-Chip Modeling
(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 ... -
Dynamic Input/Output Automata: a Formal and Compositional Model for Dynamic Systems
(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 ... -
Dynamic Input/Output Automata: A Formal Model for Dynamic Systems
(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 ... -
Dynamic Prefetching of Data Tiles for Interactive Visualization
(2015-10-19)In this paper, we present ForeCache, a general-purpose tool for exploratory browsing of large datasets. ForeCache utilizes a client-server architecture, where the user interacts with a lightweight client-side interface to ... -
Dynamically Resizable Static CMOS Logic for Fine-Grain Leakage
(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 ... -
Early Sketch Processing with Application in HMM Based Sketch Recognition
(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 ... -
Eclat: Automatic Generation and Classification of Test Inputs
(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 ... -
Efficient Cache Coherence on Manycore Optical Networks
(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 ... -
An Efficient Fill Estimation Algorithm for Sparse Matrices and Tensors in Blocked Formats
(2017-06-09)Tensors, linear-algebraic extensions of matrices in arbitrary dimensions, have numerous applications in computer science and computational science. Many tensors are sparse, containing more than 90% zero entries. Efficient ... -
Efficient Image Matching with Distributions of Local Invariant Features
(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 ...
