Abstract: In a learning device (10), an optical conversion unit (11) receives light from a learning target and uses the received light to output light according to a configuration value of a parameter. A sensing unit (13) senses the light output from the optical conversion unit (11). An estimation unit (15A) forms an estimation result for an answer to a configuration problem based on the light sensed by the sensing unit (13). An update unit (15B) calculates an update value of the parameter of the optical conversion unit (11) based on the estimation result by the estimation unit (15A), and updates the configuration value of the parameter of the optical conversion unit (11) with the calculated update value. The optical conversion unit (11) includes a plurality of optical devices in which the configuration value of the parameter is set independently of each other.
