1. A novelty detecting device comprising:
a generator configured to output reconstructed data from actual data;
a discriminator configured to receive the actual data and the reconstructed data and to produce, using the actual data and the reconstructed data, discrimination data representing whether the actual data is normal or abnormal; and
a coupling circuit configured to:
provide the actual data and the reconstructed data to the discriminator at the same time during an inference operation,
provide a first pair including two copies of the actual data during a first step of a training operation, and
provide a second pair including the actual data and the reconstructed data to the discriminator during a second step and a third step of the training operation.
