AbstractData mining on large datasets using a batch approach is time consuming and expensive. Training a large dataset can be time-consuming and in some cases may not be practical or even possible. In addition,batch learning introduces a single point of failure – this means that the training process may crash at any one point during the job and the whole process would need to be restarted. This research advances the understanding of a multi-agent approach to data mining of large datasets. An agent mining model called DMMAS (Distributed Mining Multi-Agent System) is developed for the purpose of building accurate and transparent classifiers and improving the efficiency of mining a large dataset. In our case study utilising the DMMAS model,the Pima Indian Diabetes dataset and US Census Adult dataset were used. They are well-known benchmark data from the UCI (University of California,Irvine) machine learning repository. This study found that the processing speed is improved as the result of the multi-agent mining approach,although there can be a corresponding marginal loss of accuracy. This loss of accuracy gap tends to close over time as more data becomes available. The DMMAS approach provides a new,innovative data mining model,with great research and commercial potential for distributing mining across several agents and possibly different data sources. This research also reinforces the idea that combining multiagent and data mining approaches is a logical extension for large scale data mining applications.
