Zusammenfassung:A state monitoring method and a state monitoring apparatus which achieve a lower error rate are provided. Rather than collectively processing whole measurement data, the state monitoring apparatus (100) divides the whole measurement data into a plurality of segments and processes each segment. From the measurement data, training data and test data to which an anomaly detection approach (one class support vector machine: OC-SVM) is to be applied is randomly selected. By repeatedly calculating an anomaly ratio and averaging the anomaly ratios, a result of discrimination is stabilized.
