DCAC: Dynamic Class-Aware Cache Creates Stronger Out-of-Distribution Detectors

AAAI 2026technical

Out-of-distribution (OOD) detection remains a fundamental challenge for deep neural networks, particularly due to overconfident predictions on unseen OOD samples during testing. We reveal a key insight: OOD samples predicted as the same class, or given high probabilities for it, are visually more si

Exploring Surround-View Fisheye Camera 3D Object Detection

AAAI 2026technical

In this work, we explore the technical feasibility of implementing end-to-end 3D object detection (3DOD) with surround-view fisheye camera system. Specifically, we first investigate the performance drop incurred when transferring classic pinhole-based 3D object detectors to fisheye imagery. To mitig

One for More: Selecting Generalizable Samples for Generalizable ReID Model

AAAI 2021technical

Current training objectives of existing person Re-IDentification (ReID) models only ensure that the loss of the model decreases on selected training batch, with no regards to the performance on samples outside the batch. It will inevitably cause the model to over-fit the data in the dominant positio…
