Achievements
Ensemble Learning: Multiple Decision Tree Induction PhD research 1986 to 1990.
Demonstrated use of ID3 to build a class of classifiers rather than just a single classifier.
Identified that decision tree induction algorithms like ID3 can generate multiple decision trees that can be combined to produce classifiers that perform better than the individual classifiers.
Integrated into commercial Database Management System in 1988 by BBJ Computers, into the TODAY 4GL.
Commercial Knowledge-Based Expert Systems Development
Victorian Government Departments 1987: VBARS combined business advice from multiple agencies to provide a single point of entry for the delivery of this advice to the public.
Esanda Finance 1989: Credit Assessment System. One of the first commercial Australian expert systems and still in daily operation in 2000, providing credit assessments for distributed on-line application for credit from motor vehicle dealers.
Spatial Reasoning
One of the earliest spatial expert systems developed for fire management at Kakadu National Park 1985
Awarded best paper at International conference, Avignon, France.
Spatial reasoning systems based on expectations integrated within GIS 1991
Methodologies for Exploring for Interesting Discoveries
Hot Spots Data Mining Methodology 1994
Combine rule induction with clustering to identify interesting groups within very large datasets.
Rule Evolver for Interesting Rule Discovery 1997
Employ evolutionary techniques to assist in the task of identify interesting patterns in extremely large databases.
Statistical Outlier Detection with NEC Japan
Identify under-represented patterns within extremely large databases.
Fraud Detection for the Health Insurance Commission 1998
Successful identification of cases of fraudulent behaviour
Other Data Mining Activities
Introduced the idea of building ensembles for machine learning in 1987.
With Peter Milne and Joshua Huang, set up the first data mining research and applications group in data mining in Australia in 1995, within CSIRO, Canberra.
Health Insurance Commission 1995 to 2000
Australian Taxation Office 1995 to 2000
Largest ever extraction of data from the Taxation Office
Medicare Pathology Analysis 2000
Medicare and Pharmaceutical Benefits Schemes 2000
