GeoCoBox: Box-supervised 3D Tumor Segmentation via Geometric Co-embedding

AAAI 2026technical

Data economics drives AI by optimizing data usage, reducing costs, and enhancing efficiency. In 3D tumor segmentation, efficiency is crucial due to the high demand for labor-intensive manual annotations. Box-supervised segmentation offers a promising alternative but is constrained by tumor morpholog

Mitigating Entity Hallucinations in 3D Radiology Report Generation via Dual-Stream Alignment

AAAI 2026technical

Entity hallucination poses a major challenge in radiology report generation (RRG), particularly for 3D CT scans where complex spatial contexts amplify factual errors. To address this, medical entity phrases serve as key carriers for multi-modal prompting, integrating expert knowledge into the vision

RoSE: A Role Correlation Structure-Enhanced Model for Multi-Event Argument Extraction

AAAI 2026technical

Event co-occurrences have been proven effective for event argument extraction (EAE) in previous studies; however, few have considered intra- and inter-event role correlations. Since role varies among different event types, event structure heterogeneity and overlap pose significant challenges to EAE
