The main results showed that the current research is mostly motivated by reducing the need for labelled data. This work introduces a novel anomaly detection model, by using a conditional generative adversarial network that jointly learns the generation of high-dimensional image space and the inference of latent space and shows the model efficacy and superiority over previous state-of-the-art approaches. Autoencoders attempt to learn the identity function via an encoding function from the input image to a compressed latent space and a decoding function which maps from latent space back to an image.26 Autoencoders have proven useful for anomaly detection.
