METHOD AND SYSTEM FOR AUTOMATIC POLYGRAPH TESTING USING TWO ENSEMBLES OF MACHINE LEARNING MODELS Russian patent published in 2023 - IPC G06N20/00 A61B5/16 

FIELD: polygraph testing.

SUBSTANCE: invention relates to a method and system for automatic subject testing by a polygraph using machine learning methods. The method comprises the steps of: obtaining polygraph test records containing at least sensor signals with time scales on which the beginning and end of the question are marked; receiving additional data containing at least the age of the person being checked, gender, job information; the received signals are processed using the first ensemble of ML models trained on one topic, the received signals are processed using the second ensemble of ML models trained on a combination of topics, the output values of the first and second ML ensembles are processed using the third ML model, and it is determined that the answer is false if the output value is greater than or equal to the threshold value or the answer is true if the output value is below the threshold value.

EFFECT: increased accuracy of polygraph testing.
