QUALITY CONTROL ENGINE FOR COMPLEX PHYSICAL SYSTEMS

摘要

Systems and methods for quality control for physical systems, including a quality control engine for transforming raw time series data collected from each of a plurality of sensors in the physical system into one or more sets of feature series by extracting features from the raw time series. Feature ranking scores are generated for each of the sensors by ranking each of the features using an ensemble of feature rankers, and fused importance scores are generated by aggregating the feature ranking scores for each of the sensors and combining ranking scores from each ranker in the ensemble. System quality is controlled by identifying sensors responsible for quality degradation based on the fused importance scores.

1. A method for quality control for a physical system, comprising:
transforming raw time series data collected from each of a plurality of sensors in the physical system into one or more sets of feature series by extracting features from the raw time series; generating feature ranking scores for each of the sensors by ranking each of the features using an ensemble of feature rankers; generating fused importance scores by aggregating the feature ranking scores for each of the sensors and combining ranking scores from each ranker in the ensemble; and controlling system quality by identifying sensors responsible for quality degradation based on the fused importance scores.
