    This paper challenges the common belief that LLMs need hundreds of thousands of supervised examples to learn mathematical reasoning.
  2. Halu-J: Critique-Based Hallucination Judge (2024 · 8 citations)
    LLMs often produce factually wrong statements. Retrieval-based detectors usually reduce the check to a bare label. They give little justification, can be thrown off by off-topic retrieved passages, and weigh all evidence equally. Halu-J addresses this with an open judge model of 7 billion parameters. Given a claim…
