The invention relates to anomaly detection in an installation, for example an industrial installation or an energy generation installation such as a wind turbine. Essentially, an autoencoder model is trained. This means that the user does not require expert knowledge in order to configure the anomaly detection, but rather it is enough to provide a volume of data which contains sufficient information about the normal behaviour of the machine to be monitored. In this way, the model can be trained and the future measurement data can be monitored in an automated manner. Series production repeatedly follows the same paths in the 2D plane of the PCA-reduced vectors. These paths and an identifiably continuously increasing deviation of the path from the pattern, for example caused by wear, can be detected quickly and reliably. The crucial difference from already known methods lies in the mechanism which the autoencoder uses to decide which time series sequences are anomalies. In this case, it is not the reconstruction of the autoencoder that is considered, but rather the hidden states, that is to say the vector generated by the encoder.
