1. A method for monitoring resource information and user activity comprising:

  • acquiring one or more data streams from one or more resource meters and one or more electronic device sensors;

    computing discrete events from each data stream;

    extracting a sequence of discrete sensor-meter event itemsets based on the discrete events;

    discovering frequent sensor-meter event itemsets that occur together, and determining a frequency of occurrence for each sensor-meter event itemset;

    matching rising and falling sensor-meter event itemsets based on appliance state models and the frequency of occurrence of each sensor-meter event itemset;

    identifying each individual fixture based on clustering the matched sensor-meter event itemsets using sensor-meter event features;

    classifying each fixture cluster to a fixture category using a multi-modal fixture model trained on sensor and meter event features; and

    based on the matched fixture events, fixture clusters, and categories, determining resource usage information and user activities for each fixture usage event identified.
