Bayesian autoencoders with uncertainty quantification: Towards trustworthy anomaly detection

作者:

Highlights:

• Formulation of Bayesian autoencoders is extended to quantify anomaly uncertainty.

• The total anomaly uncertainty comprises epistemic and aleatoric uncertainties.

• Rejection of predictions with high uncertainty improves performance.

• Validation of proposed methods on multiple benchmarks and real use cases.
