Abstract
Described is a system for identifying predictive keywords and generating a forecast. The system receives time-series of keyword counts (the time-series of keyword counts having a plurality of candidate keywords). The time-series of keyword counts are separated (i.e., marked or designated) into a group of time-series from active periods and a group of time-series from inactive periods. A covariance matrix is generated for each group of time-series. Generalized eigenvectors are generated between the two covariance matrices. Candidate keywords are ranked based on the generalized eigenvectors, such that candidate keywords having a rank exceeding a predetermined threshold are designated as predictive keywords. The predictive keywords are then provided to a machine learning system that generates a forecast based on the predictive keywords. Finally, a device is operated based on the forecast.
