GeoSense: Internalizing Geometric Necessity Perception for Multimodal Reasoning

ICML 2026poster

Advancing towards artificial superintelligence requires rich and intelligent perceptual capabilities. A critical frontier in this pursuit is overcoming the limited spatial understanding of Multimodal Large Language Models (MLLMs), where geometry information is essential. Existing methods often addre…

SecureSQL: Evaluating Data Leakage of Large Language Models as Natural Language Interfaces to Databases

EMNLP 2024finding

With the widespread application of Large Language Models (LLMs) in Natural Language Interfaces to Databases (NLIDBs), concerns about security issues in NLIDBs have been increasing gradually. However, research on sensitive data leakage in NLIDBs is relatively limited. Therefore, we propose a benchmar…
