Information processing system and information processing method

An information processing method for an information processing system to select a valid trained model candidate from a plurality of trained models and present the selected trained model candidate to a model user, wherein

• the information processing system includes a model management server, and a model user calculation device configured to be operated by the model user,
• the information processing method comprising:
• storing, by the model management server, in a storage unit, the plurality of trained models, a model pre-evaluation data feature that is a feature of model pre-evaluation data for pre-evaluating performance of the plurality of trained models, and model pre-evaluation accuracy that is model accuracy of the plurality of trained models pre-evaluated based on the model pre-evaluation data;
• storing, by the model user calculation device, in a storage unit, model application target data that is an application target of the trained model candidate selected from the plurality of trained models;
• calculating, by the model user calculation device, a model application target data feature that is a feature of the model application target data;
• transmitting, by the model user calculation device, the calculated model application target data feature to the model management server;
• calculating, by the model management server, similarity between the model pre-evaluation data feature and the model application target data feature received from the model user calculation device;
• calculating, by the model management server, a score for predicting validity of the trained model candidate based on the similarity and the model pre-evaluation accuracy;
• and
• presenting, by the model management server, the score together with the trained model candidate to the model user via the model user calculation device.
