Method and apparatus for anomaly detection in network

It is proposed an apparatus for anomaly detection in a network using an automatic encoder comprising an encoder and a decoder. The apparatus comprises a processor and a memory comprising computer program code, such that the apparatus performs: providing a network configuration parameter to a decoder, the network configuration parameter being used to obtain a calculated network performance metric, and determining a network performance metric based on the network configuration parameter used to obtain the calculated network performance metric. Obtaining a reconstructed network performance indicator from the decoder, comparing the reconstructed network performance indicator with the calculated network performance indicator, detecting an anomaly when a deviation between the reconstructed network performance indicator and the calculated network performance indicator is observed, providing the calculated network performance indicator to the encoder, and outputting the reconstructed network performance indicator to
