Claim Text:
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.
