Abstract
The present technology relates to a signal processing apparatus and a signal processing method that make it possible to improve the accuracy in estimating an emotion. A signal processing apparatus extracts an input feature amount on the basis of a measured biological signal, corrects a normalization coefficient according to a context related to a user, normalizes the input feature amount using the corrected normalization coefficient, and outputs a prediction label of an emotion state correspondingly to the normalized input feature amount using a machine learning model created in advance. The present technology can be applied to an emotion estimation processing apparatus.
