The Department of Information Science is one of six departments that make up the Division of Commerce at the University of Otago. The department offers courses of study leading to a major in Information Science within the BCom, BA and BSc degrees. In addition to undergraduate teaching, the department is also strongly involved in postgraduate research(More)
A modularised connectionist model, based on the mixture of experts (ME) algorithm for time series prediction, is introduced. A group of connectionist modules learn to be local experts over some commonly appeared states in a time series. The dynamics for combining the experts is a hidden Markov process, in which the states of a time series are regarded as(More)
Decision making in a complex, dynamic environment is a very difficult task that requires new techniques of computational intelligence for building adaptive, hybrid intelligent decision support systems (HIDSS). Here, a new approach is proposed based on evolving agents in a dynamic environment. Neural network and rule-based agents are evolved using methods(More)
In tackling data mining and pattern recognition tasks, finding a compact but effective set of features is often a crucial step in the whole problem solving process. In this paper we present an empirical study on feature selection for classical instrument recognition, using machine learning techniques to select and evaluate features extracted from a number(More)
In this paper we present a case study of co-training to image classification. We consider two scene classification tasks: indoors vs. outdoors and animals vs. sports. The results show that co-training with Naïve Bayes using 8-10 labelled examples obtained only 1.2-1.5% lower classification accuracy than Naïve Bayes trained on the full(More)

Content-based image retrieval techniques have been under intensively research, focusing on extracting effective low level visual features for indexing and enabling fast and accurate retrieval of individual images by matching the feature indexes. In this paper we propose to extend the content-based approach towards the problem of multimedia collection(More)

Decision making in a complex, dynamically changing environment is a difficult task that requires new techniques of computational intelligence for building adaptive, hybrid intelligent decision support systems (HIDSS). Here, a new approach is proposed based on evolving agents in a dynamic environment. Neural network and rule-based agents are evolved from(More)
