Data generation method and computer system

A data generation method for a computer system which includes a plurality of computers each including a processor, a memory connected to the processor and a network interface connected to the processor,

• at least one of the computers including a data generation unit configured to acquire a plurality of data and generate pattern data representative of a feature value for identifying a class to which an identification target belongs using the plurality of data,
• at least one of the computers including a storage unit configured to retain graph information for managing a graph configured from a plurality of vertexes and sides which connect the plurality of vertexes to each other,
• the data generation method comprising:
• a first step by the data generation unit of acquiring the plurality of data and the graph information and assuring storage regions in number equal to the number of vertexes included in the graph for storing the plurality of data;
• a second step by the data generation unit of converting each of the plurality of data into an input value and setting at least one input value to a storage region corresponding to at least one of the vertexes included in the graph;
• a third step by the data generation unit of executing an updating process for updating a value set to a storage region corresponding to a first vertex using the value set to the storage region corresponding to the first vertex and a value set to a storage region corresponding to a different vertex directly connected to the first vertex;
• and
• a fourth step by the data generation unit of outputting a set of values set to the storage regions individually corresponding to the plurality of vertexes included in the graph as the pattern data.
