Abstract: States are identified in a time ordered sequence of data that have a temporal component. Data that includes a plurality of snapshots is received. Each snapshot of the plurality of snapshots includes a plurality of sensor measurements captured from distinct sensors at a common time point. The plurality of snapshots are time ordered. Root mean square error (RMSE) values are computed between successive pairs of the plurality of snapshots in time order. A peak is identified in the computed RMSE values. A valley is identified in the computed RMSE values. A stable state is determined as occurring from the identified peak to the identified valley. The determined stable state is output.

Abstract: A method of detecting lie detection including the steps of first conditioning the subject to produce an involuntary physiological response triggered when the subject provides false statements; and secondly asking the subject to state whether each of series of statements presented to the subject are true. As the subject answers, the subject is monitored for the conditioned involuntary response. Detecting whether the subject is providing false statements is based on whether the involuntary response is observed during these answers. A system (19) for lie detection includes a computing device (21), a controller (40), and at least one conditioning interface (42, 44).
