On the difficulty of feature-based attentional modulations in visual object recognition: A modeling study.
(2004-01-14)
Numerous psychophysical experiments have shown an important role for attentional modulations in vision. Behaviorally, allocation of attention can improve performance in object detection and recognition tasks. At the neural ...
Fast Contour Matching Using Approximate Earth Mover's Distance
(2003-12-05)
Weighted graph matching is a good way to align a pair of shapesrepresented by a set of descriptive local features; the set ofcorrespondences produced by the minimum cost of matching features fromone shape to the features ...
RamboNodes for the Metropolitan Ad Hoc Network
(2003-12-17)
We present an algorithm to store data robustly in a large, geographically distributed network by means of localized regions of data storage that move in response to changing conditions. For example, data might migrate away ...
Mobilized ad-hoc networks: A reinforcement learning approach
(2003-12-04)
Research in mobile ad-hoc networks has focused on situations in whichnodes have no control over their movements. We investigate animportant but overlooked domain in which nodes do have controlover their movements. ...
On Modular Pluggable Analyses Using Set Interfaces
(2003-12-18)
We present a technique that enables the focused applicationof multiple analyses to different modules in the same program. Our researchhas two goals: 1) to address the scalability limitations of preciseanalyses by focusing ...
Rosebud: A Scalable Byzantine-Fault-Tolerant Storage Architecture
(2003-12-17)
This paper presents Rosebud, a new Byzantine faulttolerantstorage architecture designed to be highly scalableand deployable in the wide-area. To support massiveamounts of data, we need to partition the data among thenodes. ...
Risk Bounds for Mixture Density Estimation
(2004-01-27)
In this paper we focus on the problem of estimating a boundeddensity using a finite combination of densities from a givenclass. We consider the Maximum Likelihood Procedure (MLE) and the greedy procedure described by Li ...
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 ...
An Algorithm for Deciding BAPA: Boolean Algebra with Presburger Arithmetic
(2004-07-19)
We describe an algorithm for deciding the first-order multisorted theory BAPA, which combines 1) Boolean algebras of sets of uninterpreted elements (BA) and 2) Presburger arithmetic operations (PA). BAPA can express the ...
Contextual models for object detection using boosted random fields
(2004-06-25)
We seek to both detect and segment objects in images. To exploit both local image data as well as contextual information, we introduce Boosted Random Fields (BRFs), which uses Boosting to learn the graph structure and ...
