FEVER-OOD: Free Energy Vulnerability Elimination for Robust Out-of-Distribution Detection

1 code implementation2 Dec 2024 Brian K. S. Isaac-Medina, Mauricio Che, Yona F. A. Gaus, Samet Akcay, Toby P. Breckon

To mitigate these issues, we explore lower-dimensional feature spaces to reduce the null space footprint and introduce novel regularisation to maximize the least singular value of the final linear layer, hence enhancing inter-sample free energy separation.

Divide and Conquer: High-Resolution Industrial Anomaly Detection via Memory Efficient Tiled Ensemble

1 code implementation7 Mar 2024 Blaž Rolih, Dick Ameln, Ashwin Vaidya, Samet Akcay

To overcome this challenge, we present the tiled ensemble approach, which reduces memory consumption by dividing the input images into a grid of tiles and training a dedicated model for each tile location.

GANomaly: Semi-Supervised Anomaly Detection via Adversarial Training

8 code implementations17 May 2018 Samet Akcay, Amir Atapour-Abarghouei, Toby P. Breckon

Anomaly detection is a classical problem in computer vision, namely the determination of the normal from the abnormal when datasets are highly biased towards one class (normal) due to the insufficient sample size of the other class (abnormal).
