  • Fault prediction framework using temporal data mining
    Patent number: 8676432
    Abstract: A vehicle fault diagnosis and prognosis system includes a computing platform configured to receive a classifier from a remote server, the computing platform tangibly embodying computer-executable instructions for evaluating data sequences received from a vehicle control network and applying the classifier to the data sequences, wherein the classifier is configured to determine if the data sequences define a pattern that is associated with a particular fault.
    Type: Grant
    Filed: January 13, 2010
    Date of Patent: March 18, 2014
    Assignee: GM Global Technology Operations LLC
    Inventors: Debprakash Patnaik, Pulak Bandyopadhyay, Steven W. Holland, Kootaala P. Unnikrishnan, George Paul Montgomery, Jr.

  • System and method for temporal data mining
    Patent number: 7644079
    Abstract: A system for temporal data mining includes a computer readable medium having an application configured to receive at an input module a temporal data series and a threshold frequency. The system is further configured to identify, using a candidate identification and tracking module, one or more occurrences in the temporal data series of a candidate episode and increment a count for each identified occurrence. The system is also configured to produce at an output module an output for those episodes whose count of occurrences results in a frequency exceeding the threshold frequency.

  • System and method for mining of temporal data
    Patent number: 7644078
    Abstract: A system for temporal data mining includes a computer readable medium having an application configured to receive at an input module a temporal data series having events with start times and end times, a set of allowed dwelling times and a threshold frequency. The system is further configured to identify, using a candidate identification and tracking module, one or more occurrences in the temporal data series of a candidate episode and increment a count for each identified occurrence. The system is also configured to produce at an output module an output for those episodes whose count of occurrences results in a frequency exceeding the threshold frequency.
