Contextual Priming for Object Detection
(2001-09-01)
There is general consensus that context can be a rich source of information about an object's identity, location and scale. In fact, the structure of many real-world scenes is governed by strong configurational rules akin ...
Experimental Markets for Product Concepts
(2001-07-01)
Market prices are well known to efficiently collect and aggregate diverse information regarding the value of commodities and assets. The role of markets has been particularly suitable to pricing financial securities. This ...
Recognizing Indoor Scenes
(2001-07-25)
We propose a scheme for indoor place identification based on the recognition of global scene views. Scene views are encoded using a holistic representation that provides low-resolution spatial and spectral information. The ...
The Audiomomma Music Recommendation System
(2001-07-01)
We design and implement a system that recommends musicians to listeners. The basic idea is to keep track of what artists a user listens to, to find other users with similar tastes, and to recommend other artists that these ...
Exploring Object Perception with Random Image Structure Evolution
(2001-03-01)
We have developed a technique called RISE (Random Image Structure Evolution), by which one may systematically sample continuous paths in a high-dimensional image space. A basic RISE sequence depicts the evolution of an ...
An Empirical Comparison of SNoW and SVMs for Face Detection
(2001-01-01)
Impressive claims have been made for the performance of the SNoW algorithm on face detection tasks by Yang et. al. [7]. In particular, by looking at both their results and those of Heisele et. al. [3], one could infer that ...
Policy Improvement for POMDPs Using Normalized Importance Sampling
(2001-03-20)
We present a new method for estimating the expected return of a POMDP from experience. The estimator does not assume any knowle ge of the POMDP and allows the experience to be gathered with an arbitrary set of policies. ...
An Electronic Market-Maker
(2001-04-17)
This paper presents an adaptive learning model for market-making under the reinforcement learning framework. Reinforcement learning is a learning technique in which agents aim to maximize the long-term accumulated rewards. ...
Discontinuous modelling of strain localisation and failure
(Delft University of Technology, 2001-06-12)
The computational simulation of failure in solids poses many challenges. A proper understanding of how structures respond under loading, both before and past the peak load, is important for safe and economical constructions. ...
Analysis of delamination growth with discontinuous finite elements
(Solids, Structures and Coupled Problems in EngineeringSolids, Structures and Coupled Problems in Engineering, 2001)
In this contribution a new finite element is presented for the simulation of delamination growth in thin layered composite materials. The element is based on the solid-like shell element, a volume element that can be used ...
