Evaluating Boundary-Aware Losses for U-KAN on BraTS 2023 Brain Tumor Segmentation

This study evaluates five boundary-aware loss functions within 2D and 3D U-KAN pipelines for BraTS 2023 brain tumor segmentation and concludes that while Staged Boundary Loss showed some pipeline-dependent improvements, boundary-aware training generally fails to provide consistent or reproducible advantages over standard region-based objectives.

A Wearable Non-Visual Guidance System with an Inspectable Spatial-Cue Core

This paper presents a wearable non-visual guidance system that integrates smart glasses, an edge computing unit, and a haptic wristband to convert spatial perception into actionable cues, demonstrating significantly reduced collision rates for blind users and equivalent performance for low-vision users compared to traditional white canes.

Red-Teaming African-Language LLMs: Safety Alignment Failures Across Low-Resource Languages

This paper presents the first systematic red-team evaluation of African-language Large Language Models, revealing that despite varying sizes and alignment techniques, models across Hausa, Swahili, Yoruba, and Igbo exhibit significant safety vulnerabilities to culturally grounded adversarial attacks, particularly in propaganda and harm generation categories.

Semantic boundary refinement for traffic salient object segmentation using residual logit correction

This paper introduces EdgeRefine, a lightweight residual logit correction module for DeepLabV3 and SegFormer that improves semantic boundary refinement in traffic salient object segmentation by explicitly defining supervised boundaries as morphological mask edges, yielding modest but measurable gains in overlap and boundary metrics while revealing specific limitations in geometric consistency and cross-domain transfer.
