Exploiting Autoencoder's Weakness to Generate Pseudo Anomalies

Marcella Astrid, Muhammad Zaigham Zaheer, Djamila Aouada +1

Due to the rare occurrence of anomalous events, a typical approach to anomaly detection is to train an autoencoder (AE) with normal data only so that it learns the patterns or repr…
