HugRAG: Hierarchical Causal Knowledge Graph Design for RAG

ICML 2026poster

Retrieval augmented generation (RAG) has enhanced large language models by enabling access to external knowledge, with graph-based RAG emerging as a powerful paradigm for structured retrieval and reasoning. However, existing graph-based methods often over-rely on surface-level node matching and lack…

Grammars of Formal Uncertainty: When to Trust LLMs in Automated Reasoning Tasks

NeurIPS 2025poster

Large language models (LLMs) show remarkable promise for democratizing automated reasoning by generating formal specifications. However, a fundamental tension exists: LLMs are probabilistic, while formal verification demands deterministic guarantees. This paper addresses this epistemological gap by…
