Receive operator input correcting product information when precision of identification of product is less than reference value

Abstract

The present invention provides a processing apparatus () including: a classification execution unit () that executes class classification, based on an inference device; a computation unit () that computes a precision of a class determined by the class classification; a processing unit () that outputs a class determined by the class classification and accepts a correct/incorrect input from an operator when the precision is less than a reference value; and a registration unit () that registers a product determined by the class classification as a purchase target when the precision is equal to or more than the reference value, and registers a product determined by a correct/incorrect input from the operator as a purchase target when the precision is less than the reference value.
