Data processing apparatus, data processing method, and storage medium

A data processing method comprising:

• a computer acquiring graph-structured data describing a connection relation between nodes;
• setting a first network representing the acquired graph-structured data;
• and
• deriving a parameter of the first network such that a feature quantity of an output layer of an evaluation target node in the first network approaches a reward and a feature quantity of an output layer of an operation node becomes a feature quantity causing the feature quantity of the output layer of the evaluation target node to approach the reward.

A non-transitory computer-readable storage medium storing a program causing a computer to:

• acquire graph-structured data describing a connection relation between nodes;
• set a first network representing the acquired graph-structured data;
• and
• derive a parameter of the first network such that a feature quantity of an output layer of an evaluation target node in the first network approaches a reward and a feature quantity of an output layer of an operation node becomes a feature quantity causing the feature quantity of the output layer of the evaluation target node to approach the reward.
