Abstract: An anomalous region detection system includes a controller configured to, receive data being grouped in patches, encode, via parameters of an encoder, the data to obtain a series of local latent representations for each patch, calculate, for each patch, a Contrastive Predictive Coding (CPC) loss from the local latent representations to obtain updated parameters, update the parameters of the encoder with the updated parameters, score each of the series of the local latent representations, via the Contrastive Predictive Coding (CPC) loss, to obtain a score associated with each patch, smooth the score to obtain a loss region, mask the data associated with the loss region to obtain verified data, and output the verified data.
