Abstract: A method, system, and computer program product for fault data correlation in a diagnostic system are provided. The method includes receiving the fault data including a plurality of faults collected over a period of time, and identifying a plurality of episodes within the fault data, where each episode includes a sequence of the faults. The method further includes calculating a frequency of the episodes within the fault data, calculating a correlation confidence of the faults relative to the episodes as a function of the frequency of the episodes, and outputting a report of the faults with the correlation confidence.

Abstract: A method, system, and apparatus for temporal data mining is disclosed. The method includes receiving as input a temporal data series comprising events with start times and end times, a set of allowed dwelling times, and a threshold frequency. The method also includes finding all frequent principal episodes of a particular length in the temporal data series having dwelling times within the allowed dwelling times. The method includes steps executed in successive passes through the temporal data series.

Abstract: A method, system, and apparatus for temporal data mining is disclosed. The method includes receiving as input a temporal data series comprising time-stamped events, and a threshold frequency. An aspect of this technology is the defining of appropriate frequency counts for non-overlapping and non-interleaved episodes. Two frequency measures and embodiments for obtaining frequent episodes are described. The method includes finding all frequent episodes of a particular length in the temporal data series. The method includes steps executed in successive passes through the temporal data series.
