Functional Differential Geometry
(2005-02-02)
Differential geometry is deceptively simple. It is surprisingly easyto get the right answer with unclear and informal symbol manipulation.To address this problem we use computer programs to communicate aprecise understanding ...
Improving 802.11 Range with Forward Error Correction
(2005-02-24)
The ISO/IEC 8802-11:1999(E) specification uses a 32-bit CRC for error detection and whole-packet retransmissions for recovery. In long-distance orhigh-interference links where the probability of a bit error is high,this ...
Automated Audio-visual Activity Analysis
(2005-09-20)
Current computer vision techniques can effectively monitor gross activities in sparse environments. Unfortunately, visual stimulus is often not sufficient for reliably discriminating between many types of activity. In ...
Collective Choice with Uncertain Domain Moldels
(2005-08-16)
When groups of individuals make choices among several alternatives, the most compelling social outcome is the Condorcet winner, namely the alternative beating all others in a pair-wise contest. Obviously the Condorcet ...
LabelMe: a database and web-based tool for image annotation
(2005-09-08)
Research in object detection and recognition in cluttered scenes requires large image collections with ground truth labels. The labels should provide information about the object classes present in each image, as well as ...
Spatial and Temporal Abstractions in POMDPs Applied to Robot Navigation
(2005-09-27)
Partially observable Markov decision processes (POMDPs) are a well studied paradigm for programming autonomous robots, where the robot sequentially chooses actions to achieve long term goals efficiently. Unfortunately, ...
Ultra-fast Object Recognition from Few Spikes
(2005-07-06)
Understanding the complex brain computations leading to object recognition requires quantitatively characterizing the information represented in inferior temporal cortex (IT), the highest stage of the primate visual stream. ...
Boosting a Biologically Inspired Local Descriptor for Geometry-free Face and Full Multi-view 3D Object Recognition
(2005-07-07)
Object recognition systems relying on local descriptors are increasingly used because of their perceived robustness with respect to occlusions and to global geometrical deformations. Descriptors of this type -- based on ...
A Theory of Object Recognition: Computations and Circuits in the Feedforward Path of the Ventral Stream in Primate Visual Cortex
(2005-12-19)
We describe a quantitative theory to account for the computations performed by the feedforward path of the ventral stream of visual cortex and the local circuits implementing them. We show that a model instantiating the ...
Simultaneous Localization and Tracking in Wireless Ad-hoc Sensor Networks
(2005-05-31)
In this thesis we present LaSLAT, a sensor network algorithm thatsimultaneously localizes sensors, calibrates sensing hardware, andtracks unconstrained moving targets using only range measurementsbetween the sensors and ...
