Title:
MODEL TRAINING DEVICE AND MODEL TRAINING METHOD
Document Type and Number:
Japanese Patent JP2023013947
Kind Code:
A
Abstract:
To improve accuracy of a model.SOLUTION: A model training device according to the present embodiment comprises a training unit, an evaluation unit, a grouping unit, and a model training information specification unit. The training unit learns a dataset including medial images as learning data to obtain an initial learning model. The evaluation unit evaluates the initial learning model by using global metrics to acquire abnormal datasets to be outliers from among a plurality of datasets used for the evaluation. The grouping unit groups the plurality of abnormal datasets acquired by the evaluation unit by using local metrics to obtain a plurality of abnormal dataset groups. The model training information specification unit specifies model training information for each of the abnormal dataset groups obtained by the grouping unit.SELECTED DRAWING: Figure 1B
