Reducing computational load of processing measurements of affective response

摘要

Systems and methods for reducing the computational load of processing measurements of affective response of a user to content. A content emotional response analyzer (content ERA) receives a segment of content, analyzes it, and outputs an indication regarding whether a value related to a predicted emotional response to the segment reaches a predetermined threshold. Based on the indication, a controller selects a processing level, from among at least first and second processing levels, for a processor to process measurements of affective response. The first level may be selected when the value does not reach the predetermined threshold, while the second level may be selected when the value reaches it. The processor is configured to utilize significantly fewer computation cycles to process data operating at the first processing level, compared to the number of computation cycles it utilizes to process data operating at the second processing level.

1. A system configured to reduce computational load involved in processing measurements of affective response of a user to content, comprising:
a content emotional response analyzer (content ERA) configured to: receive a first segment of content, analyze the first segment, and output a first indication indicating that a first value related to an emotional response to the first segment does not reach a first predetermined threshold; and a controller configured to select, based on the first indication, a first processing level for a processor to process measurements of affective response of the user to the first segment; the content ERA is further configured to: receive a second segment of content, analyze the second segment, and output a second indication indicating that a second value related to a prediction of emotional response to the second segment reaches a second predetermined threshold; the controller is further configured to select, based on the second indication, a second processing level for the processor to process measurements of affective response of the user to the second segment; wherein, per volume unit of measurement data, number of computation cycles utilized by the processor to process, at the first processing level, measurements of the affective response of the user to the first segment, is at least 50% lower than number of computation cycles utilized by the processor to process, at the second processing level, measurements of the affective response of the user to the second segment.
