Unsupervised Anomaly Detection with Adversarial Mirrored AutoEncoders [article]

Gowthami Somepalli, Yexin Wu, Yogesh Balaji, Bhanukiran Vinzamuri, Soheil Feizi
2021 arXiv   pre-print
Our method outperforms the current state-of-the-art methods for anomaly detection on several OOD detection benchmarks.  ...  First, we propose Adversarial Mirrored Autoencoder (AMA), a variant of Adversarial Autoencoder, which uses a mirrored Wasserstein loss in the discriminator to enforce better semantic-level reconstruction  ...  Authors thank Ritesh Soni, Steven Loscalzo, Bayan Bruss, Samuel Sharpe and Jason Wittenbach for helpful discussions.  ...

A Unified Survey on Anomaly, Novelty, Open-Set, and Out-of-Distribution Detection: Solutions and Future Challenges [article]

Mohammadreza Salehi, Hossein Mirzaei, Dan Hendrycks, Yixuan Li, Mohammad Hossein Rohban, Mohammad Sabokrou
2021 arXiv   pre-print
To date, several research domains tackle the problem of detecting unfamiliar samples, including anomaly detection, novelty detection, one-class learning, open set recognition, and out-of-distribution detection  ...  Despite having similar and shared concepts, out-of-distribution, open-set, and anomaly detection have been investigated independently.  ...  Asano for the extremely useful discussions and for reviewing the paper prior to submission.  ...

Deep Neural Networks [article]

Randall Balestriero, Richard Baraniuk
2017 arXiv   pre-print
Answering those points would provide theoretical perspectives for further developments based on a common ground.  ...  Some fundamental problems remain: (1) the lack of a mathematical framework providing an explicit and interpretable input-output formula for any topology, (2) quantification of DNNs stability regarding  ...  "ambiguous" inputs,anomaly detection, allow for semisup with state-of-the-art performances and unsupervised training, clustering Flat-Minima, Generalization: define the concept of generalization for DNNs  ...
