Adaptive, evolving, hybrid connectionist systems for image pattern recognition
The chapter presents a new methodology for building adaptive, incremental learning systems for image pattern classification. The systems are based on dynamically evolving fuzzy neural networks that are neural architectures ...
Agent modelling with Petri nets
The use of intelligent software agents is a modelling paradigm that is gaining increasing attention in the applications of distributed systems. This paper identifies essential characteristics of agents and shows how they ...
Exploiting the advantages of object-oriented programming in the implementation of a database design environment
In this paper, we describe the implementation of a database design environment (Swift) that incorporates several novel features: Swift’s data modelling approach is derived from viewpoint-oriented methods; Swift is implemented ...
Reasonable security safeguards for small to medium organisations
In today’s world most businesses, large and small, depend on their computer(s) to provide vital functions consistently and without interruption. In many organizations the loss of the computer function could mean the ...
Environmental decisions with spatial process modelling
This paper first describes the difficulties inherent in supporting a class of environmental problems, those involved in Regional Environmental Decision Making. A set of conceptual criteria are presented along with discussion ...
Wayfinding/navigation within a QTVR virtual environment: preliminary results
This paper reports on an investigation into wayfinding principles, and their effectiveness within a virtual environment. To investigate these principles, a virtual environment of an actual museum was created using QuickTime ...
Alternatives to regression models for estimating software projects
The use of ‘standard’ regression analysis to derive predictive equations for software development has recently been complemented by increasing numbers of analyses using less common methods, such as neural networks, fuzzy ...
Establishing relationships between specification size and software process effort in CASE environments
Advances in software process technology have rendered many existing methods of size assessment and effort estimation inapplicable. The use of automation in the software process, however, provides an opportunity for the ...
Politics and techniques of data encryption
Cryptography is the art or science, depending on how you look at it, of keeping messages secure. It has been around for a couple of thousand years in various forms. The Spartan Lysander and even Caesar made use of cryptography ...
Spatial-temporal adaptation in evolving fuzzy neural networks for on-line adaptive phoneme recognition
The paper is a study on a new class of spatial-temporal evolving fuzzy neural network systems (EFuNNs) for on-line adaptive learning, and their applications for adaptive phoneme recognition. The systems evolve through ...
