SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM

WIPO Patent Application WO/2021/176985

A1

This signal processing device comprises: a data input unit to which image data is input; an output unit that outputs an output value on the basis of the data input to the data input unit; an expectation value feedback calculator that calculates the difference between the output value and an expectation value based on the input data; and a Bayesian estimator that receives input of information pertaining to the difference and information based on the image data, and that performs machine learning for bringing the output value close to the expectation value on the basis of the input information and searches for an optimal configuration.
