Abstract
A training apparatus includes a circuitry. The circuitry inputs a bag that is a set of an instance to an identifier and outputs a probability sequence including a probability that each instance belonging to the bag corresponds to a target. The circuitry calculates a bag likelihood that is a probability that specific instances corresponding to the target are included in the bag. The circuitry outputs an expected instance quantity regarding a quantity of the specific instances included in the bag. The circuitry calculates a parameter update amount based on teaching data, the bag likelihood, and the expected instance quantity, and updates a parameter of the identifier based on the parameter update amount.
