Title:
SIGNAL PROCESSING DEVICE AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286313
Kind Code:
A1
Abstract:
The present art relates to a signal processing device and method that can improve robustness against noise of emotion estimation. A signal processing device extracts, as a feature value on the basis of a measured biological signal, a physiological index contributing to an emotion, outputs, for time series data on the feature value, time series data on the prediction label of an emotion status according to an identification model constructed in advance, and outputs an emotion estimation result on the basis of the result of a weighted sum performed on the prediction label by using a prediction label reliability that is the reliability of the prediction label. The present art can be applied to emotion estimation systems.
