ASTRA: Adaptive Semantic Tree Reasoning Architecture for Complex Table Question Answering arXiv:2604.08999v2 Announce Type: replace Abstract: Table serialization remains a critical bottleneck for Large Language Models (LLMs) in complex table question answering, hindered by challenges such as structural neglect, representation gaps, and reasoning opacity. Existing serialization methods fail to capture explicit hierarchies and lack schema flexibility, while current tree-based approaches suffer fr
