Connectionist-based information systems: a proposed research theme
General Characteristics of the Theme
• Emerging technology with rapidly growing practical applications
• Nationally and internationally recognised leadership of the University of Otago
• Already established organisation ...
From hybrid adjustable neuro-fuzzy systems to adaptive connectionist-based systems for phoneme and word recognition
This paper discusses the problem of adaptation in automatic speech recognition systems (ASRS) and suggests several strategies for adaptation in a modular architecture for speech recognition. The architecture allows for ...
Improved learning strategies for multimodular fuzzy neural network systems: a case study on image classification
This paper explores two different methods for improved learning in multimodular fuzzy neural network systems for classification. It demonstrates these methods on a case study of satellite image classification using 3 ...
Evolving localised learning for on-line colour image quantisation
Although widely studied for many years, colour image quantisation remains a challenging problem. We propose to use an evolving self-organising map model for the on-line image quantisation tasks. Encouraging results are ...
Neuro-fuzzy methods for environmental modelling
This paper describes combined approaches of data preparation, neural network analysis, and fuzzy inferencing techniques (which we collectively call neuro-fuzzy engineering) to the problem of environmental modelling. The ...
Modelling the emergence of speech sound categories in evolving connectionist systems
We report on the clustering of nodes in internally represented acoustic space. Learners of different languages partition perceptual space distinctly. Here, an Evolving Connectionist-Based System (ECOS) is used to model the ...
A membership function selection method for fuzzy neural networks
Fuzzy neural networks provide for the extraction of fuzzy rules from artificial neural network architectures. In this paper we describe a general method, based on statistical analysis of the training data, for the selection ...
Connectionist methods for classification of fruit populations based on visible-near infrared spectrophotometry data
Variation in fruit maturation can influence harvest timing and duration, post-harvest fruit attributes and consumer acceptability. Present methods of managing and identifying lines of fruit with specific attributes both ...
The concepts of hidden Markov model in speech recognition
The speech recognition field is one of the most challenging fields that has faced scientists for a long time. The complete solution is still far from reach. The efforts are concentrated with huge funds from the companies ...
Evolving self-organizing maps for on-line learning, data analysis and modelling
In real world information systems, data analysis and processing are usually needed to be done in an on-line, self-adaptive way. In this respect, neural algorithms of incremental learning and constructive network models are ...
