System And Method For Non Linear Signal Extraction And Structural Drift Detection

Abstract: Various embodiments of the present invention describes 5 optimizing energy performance evaluation. The invention describes a system with an energy consumption data unit configured to determine an energy consumption data associated with an entity in different cycles. A structural drift identifier unit is configured to classify the energy consumption data into multiple individual drift classes. A non-linear signal extractor unit is configured to extract 10 a set of non-linear signals from the energy consumption data by defining cycles based on the frequency of energy consumption data and evaluating the variance in energy consumption data. The system comprises an individual drift class refinement unit configured to refine individual drift classes by eliminating first weak drifts using the set of non-linear signals resulting into refined individual 15 drift classes. A collective drift refinement unit configured to collate and collectively refine individual drift instances of all the refined individual drift classes into refined collective drift classes by eliminating second weak drifts.
