Abstract
Abstract A method, apparatus, and article of manufacture for a computer-implemented random reliability engine for computer-implemented dimension reduction using association rules for data mining application. The data mining is performed by the computer to retrieve data from a data store stored on a data storage device coupled to the computer. The data store has records that have multiple attributes. The multiple attributes of a table are clustered to produce a plurality of sets of attributes. Each set of attributes is clustered to obtain data mining attributes.
