OOD Aware Supervised Contrastive Learning

no code implementations3 Oct 2023 Soroush Seifi, Daniel Olmeda Reino, Nikolay Chumerin, Rahaf Aljundi

Our solution is simple and efficient and acts as a natural extension of the closed-set supervised contrastive representation learning.

Contrastive Classification and Representation Learning with Probabilistic Interpretation

no code implementations7 Nov 2022 Rahaf Aljundi, Yash Patel, Milan Sulc, Daniel Olmeda, Nikolay Chumerin

In this work, we investigate the possibility of learning both the representation and the classifier using one objective function that combines the robustness of contrastive learning and the probabilistic interpretation of cross entropy loss.

Road Anomaly Detection by Partial Image Reconstruction With Segmentation Coupling

1 code implementation ICCV 2021 Tomas Vojir, Tomas Sipka, Rahaf Aljundi, Nikolay Chumerin, Daniel Olmeda Reino, Jiri Matas

To that end, we propose a reconstruction module that can be used with many existing semantic segmentation networks, and that is trained to recognize and reconstruct road (drivable) surface from a small bottleneck.
