| Abstract(in English) | Monitoring with multiple sensors is important for system diagnosis, and active researches are being conducted using machine learning. However, treating multiple sensors having different units may result in the loss of information necessary for anomaly detection, and the handling and interpretation of sensor data, which do not lose information are desired in the industry. In this paper, we analyze equipment deterioration and anomalies based on the changes of information entropy. That is to say, we show that entropy, Kullback-Leibler divergence and mutual information, which are the basic concepts of information theory, are of great value for anomaly detection and diagnosis. The keywords for each role are unification, duality and dependency. |
