چکیده
We present a method for inducing a set of rules from time series data, which is originated from a system monitoring process. The proposed method is called MAPS (Mining Aberrant Patterns in Sequences) and it may be used in decision support or in control to identify faulty system states. It consists of four parts: training, identification, mining and prediction. In order to improve the flexibility of the event identification, we employ fuzzy sets and propose a method that extracts membership functions from statistical measures of the time series. The proposed approach integrates fuzzy logic and mining in a seamless ways. Some of the existing mining algorithms have been modified to accommodate the need of discovering fuzzy event pattern.
