INTEGRATED MODEL GENERATION METHOD, IMAGE INSPECTION SYSTEM, IMAGE INSPECTION MODEL GENERATION DEVICE, IMAGE INSPECTION MODEL GENERATION PROGRAM, AND IMAGE INSPECTION DEVICE

An inspection model adapted to an environment of a site is generated with a lighter learning workload. A plurality of first element models different from each other in a specific feature are prepared. A second model is generated by adjusting at least one of the plurality of first element models to adapt to adjustment data different from training data of the model. From a set of element models including the plurality of first element models and the second element model, a plurality of the element models including at least one of the second element models are selected. An integrated model is generated by integrating the plurality of the element models selected. The integrated model outputs any of classes into which input data is classified based on presence or absence of all of a plurality of the specific features related to the plurality of the element models selected.
