1. A method, comprising:
- identifying a signal and a disturbance using historical data associated with one or more process variables;
decomposing the signal and the disturbance at a plurality of resolution levels;
identifying a plurality of points associated with the decomposed signal using the decomposed signal and the decomposed disturbance;
selecting at least some of the points; and
extracting a plurality of data segments from the signal, the data segments associated with the selected points.

Abstract
A method includes identifying a signal and a disturbance using historical data associated with one or more process variables. The method also includes decomposing the signal and the disturbance at a plurality of resolution levels. The method further includes identifying a plurality of points associated with the decomposed signal using the decomposed signal and the decomposed disturbance. In addition, the method includes selecting at least some of the points and extracting a plurality of data segments from the signal, where the data segments are associated with the selected points.
