Abstract(in English) | Anomaly detection models based on sensor data for preventive maintenance of facilities, need to be updated based on continuous evaluation (accuracy and interpretability). However, since the correct labels cannot be obtained for the anomaly detection task, we must evaluate the prediction results by visual confirmation. In this study, we propose an ensemble model that combines several models specialized for specific types of failures, which are created from domain knowledge. The proposed ensemble model is expected to reduce the amount of visual check and the side effects of updating by combining the models before and after updating, thus making the model updating process more efficient. |
