Concept learning is a computationally demanding task that involves searching large hypothesis spaces containing candidate descriptions. Stochastic search combined with parallel processing provide a promising approach to successfully deal with such ...
In this paper we provide a survey on LLL lattice basis reduction in practice. We introduce several new heuristics as to speed up known lattice basis reduction methods and improve the quality of the computed reduced lattice basis in practice. We analyze ...
This paper presents a Course Of Action Scheduling Tool (COAST) to support operations planning in the Australian Defence Force (ADF). COAST is a software tool based on Coloured Petri Nets (CPNs or CP-nets) and Design/CPN. It is developed with an ...
We present an environment for web-based simulation of influence nets to be used for operational planning. Previous work in this field has shown how influence nets, which are used for probabilistic modelling, can be extended with time and then translated ...
The Reactive Search (RS) method proposes the integration of a simple history-sensitive (machine learning) scheme into local search for the on-line determination of free parameters. In this paper a new RS algorithm is proposed for the approximated ...
Speech recognition is an area with a considerable literature, but there is little discussion of the topic within the computer science algorithms literature. Many computer scientists, however, are interested in the computational problems of speech ...
Lambert's model for body reflection is widely used in computer graphics. It is used extensively by rendering techniques such as radiosity and ray tracing. For several real-world objects, however, Lambert's model can prove to be a very inaccurate ...
In this work we render non-opaque anisotropic media. A mathematical formalism is described in which polarization effects resulting from light/material interactions are represented as transformation matrices.
When applying the matrices a skewing is ...
A wavelength based bidirectional reflectance function is developed for use in realistic image synthesis. A geodesic sphere is employed to represent the BRDF, and a novel data structure is used to store this description and to recall it for rendering ...
This paper describes a methodology for using the matrix-vector multiply and scan conversion hardware present in many graphics workstations to rapidly approximate the optical flow in a scene. The optical flow is a 2-dimensional vector field describing ...
