SYSTEM AND METHOD OF MINING TIME-CHANGING DATA STREAMS USING A DYNAMIC RULE CLASSIFIER HAVING LOW GRANULARITY

摘要

A dynamic rule classifier for mining a data stream includes at least one window for viewing data contained in the data stream and a set of rules for mining the data. Rules are added and the set of rules are updated by algorithms when an drift in a concept within the data occurs, causing unacceptable drops in classification accuracy. The dynamic rule classifier is also implemented as a method and a computer program product.
