  • Methods and apparatus of analyzing electrical power grid data
    Patent number: 9753066
    Abstract: Apparatus and methods of processing large-scale data regarding an electrical power grid are described. According to one aspect, a method of processing large-scale data regarding an electrical power grid includes accessing a large-scale data set comprising information regarding an electrical power grid; processing data of the large-scale data set to identify a filter which is configured to remove erroneous data from the large-scale data set; using the filter, removing erroneous data from the large-scale data set; and after the removing, processing data of the large-scale data set to identify an event detector which is configured to identify events of interest in the large-scale data set.
    Type: Grant

  • Methods for Discovering Analyst-Significant Portions of a Multi-Dimensional Database
    Publication number: 20110119281
    Abstract: Methods for discovering portions of a multi-dimensional database that are significant to an analyst can be computer-implemented. The methods can include specifying a data view having at least two dimensions and all records of the database. A plurality of operation iterations are then performed on the data view, wherein each iteration is a chain operation, a hop operation or an anti-hop operation. The operation iterations are ceased upon satisfaction of a termination criteria. The resulting data view can then be presented to an analyst. The methods can facilitate a users' knowledge discovery tasks and assist in finding relevant patterns, trends, and anomalies.
