Robust Evidential Learning Through Latent Consistency

The paper introduces CLEAR, a lightweight, task‑agnostic post‑hoc method that enhances evidential robustness in deep learning models without retraining. CLEAR uses held‑out calibration data to map the geometry of the model’s latent space, then generates perturbation views at inference to detect latent conflict. When high conflict is found, CLEAR selectively reduces evidential strength while preserving evidence for latent‑consistent inputs, achieving significant improvements in OOD and adversarial AUROC on ImageNet→CUB and running much faster than competing methods.

Three-Way Open-Set Detection for Robust Autonomous Navigation

The paper proposes a three-way open-set detection framework for autonomous navigation, classifying each detection as a known object, unknown object, or background based on a pretrained detector’s outputs. It introduces domain generalization and adaptation methods, evaluates them across various detector families and benchmarks, and demonstrates that this approach improves safety and efficiency in simulated navigation missions compared to binary detection methods.

Bayesian 3D Steerable CNNs: Enabling Equivariance and Uncertainty Quantification Simultaneously

arXiv:2606. 15479v1 Announce Type: cross Abstract: Steerable convolutional neural networks (Steerable-CNNs) guarantee SE(3)-equivariance by parameterizing kernels as linear combinations of steerable basis functions, but their deterministic nature precludes uncertainty quantification - limiting their use in settings where confidence estimates are essential.

Towards Reliable Vision-Language Models for Autonomous Driving

The paper evaluates five vision‑language models on autonomous driving tasks under various visual input conditions, finding that visual corruption affects accuracy and confidence differently across models and datasets. It then tests Visual Evidence Augmentation (VEA) as an inference‑time technique to enhance reliability, observing mixed improvements depending on the model and setting.
