Using The Barton Libraries Dataset As An RDF benchmark
(2007-07-06)
This report describes the Barton Libraries RDF dataset and Longwell querybenchmark that we use for our recent VLDB paper on Scalable Semantic WebData Management Using Vertical Partitioning.
Learning complex cell invariance from natural videos: A plausibility proof
(2007-12-26)
One of the most striking feature of the cortex is its ability to wire itself. Understanding how the visual cortex wires up through development and how visual experience refines connections into adulthood is a key question ...
Certified Computation
(2001-04-30)
This paper introduces the notion of certified computation. A certified computation does not only produce a result r, but also a correctness certificate, which is a formal proof that r is correct. This can greatly enhance ...
Plan-view Trajectory Estimation with Dense Stereo Background Models
(2001-02-01)
In a known environment, objects may be tracked in multiple views using a set of back-ground models. Stereo-based models can be illumination-invariant, but often have undefined values which inevitably lead to foreground ...
Exploration in Gradient-Based Reinforcement Learning
(2001-04-03)
Gradient-based policy search is an alternative to value-function-based methods for reinforcement learning in non-Markovian domains. One apparent drawback of policy search is its requirement that all actions be 'on-policy'; ...
Teaching an Old Robot New Tricks: Learning Novel Tasks via Interaction with People and Things
(2003-06-20)
As AI has begun to reach out beyond its symbolic, objectivist roots into the embodied, experientialist realm, many projects are exploring different aspects of creating machines which interact with and respond to the world ...
Stereo-Based Head Pose Tracking Using Iterative Closest Point and Normal Flow Constraint
(2003-05-01)
In this text, we present two stereo-based head tracking techniques along with a fast 3D model acquisition system. The first tracking technique is a robust implementation of stereo-based head tracking designed for ...
Compact Representations for Fast Nonrigid Registration of Medical Images
(2003-07-04)
We develop efficient techniques for the non-rigid registration of medical images by using representations that adapt to the anatomy found in such images. Images of anatomical structures typically have uniform intensity ...
Safe Distributed Coordination of Heterogeneous Robots through Dynamic Simple Temporal Networks
(2003-05-30)
Research on autonomous intelligent systems has focused on how robots can robustly carry out missions in uncertain and harsh environments with very little or no human intervention. Robotic execution languages such as RAPs, ...
From First Contact to Close Encounters: A Developmentally Deep Perceptual System for a Humanoid Robot
(2003-06-01)
This thesis presents a perceptual system for a humanoid robot that integrates abilities such as object localization and recognition with the deeper developmental machinery required to forge those competences out of raw ...
