| 20160084233 | SYSTEMS AND METHODS FOR VALIDATING WIND FARM PERFORMANCE MEASUREMENTS - The present disclosure is directed to systems and methods for validating and/or identifying wind farm performance measurements so as to optimize wind farm performance. The method includes measuring operating data from one or more wind turbines of the farm. Another step includes generating a plurality of baseline models of performance of the wind farm from at least a portion of the operating data. Thus, each of the baseline models of performance is developed from a different portion of operating data so as to provide comparable models. The method also includes selecting an optimal baseline model and comparing the optimal baseline model with actual performance of the wind farm. In a particular embodiment, the actual performance of the wind farm is determined after one or more wind turbines of the wind farm is modified by one or more upgrades. | 03-24-2016 |

| 20110022355 | Network Characterization, Feature Extraction and Application to Classification - Methods, systems and apparatus for characterizing networks are presented. For example, a method of characterizing a network represented by a plurality of nodes and a plurality of edges is provided. The method may be implemented on a processor device and includes calculating, for example, by the processor device, a passthrough count of at least a portion of the network. The passthrough count includes a count of a number of passthroughs in the at least a portion of the network. A passthrough includes one of the plurality of nodes, a directed edge of the plurality of edges coupled to the one of the plurality of nodes, and another edge of the plurality of edges coupled to the one of the plurality of nodes. At most one of the directed edge and the other edge is directed towards the one of the plurality of nodes. At most one of the directed edge and the other edge is directed away from the one of the plurality of nodes. | 01-27-2011 |

| 20140257832 | IDENTIFYING POTENTIAL AUDIT TARGETS IN FRAUD AND ABUSE INVESTIGATIONS - Detecting fraud in the health care industry includes selecting a given focus scenario (e.g., prescription rate in a certain drug therapeutic class) for audit analysis, and constructing baseline models with the appropriate normalizations to describe the expected behavior within the focus area. These baseline models are then used, in conjunction with statistical hypothesis testing, to identify entities whose behavior diverges significantly from their expected behavior according to the baseline models. A Likelihood Ratio (LR) score over the relevant claims with respect to the baseline model is obtained for each entity, and the p-value significance of this score is evaluated to ensure that the abnormal behavior can be identified at the specified level of statistical significance. The approach may be used as part of a preliminary computer-aided audit process in which the relevant entities with the abnormal behavior are identified with high selectivity for a subsequent human-intensive audit investigation. | 09-11-2014 |
