Verifier-Guided Self-Consistency: Test-Time Reasoning with Imperfect Generators and Verifiers

Ekaterina Fadeeva, Xueyan Li, Mrinmaya Sachan +1

Large language models can solve many multi-step reasoning problems, but their reasoning remains brittle: plausible intermediate steps often lead to incorrect answers. Improving rea…

Idea Traces: Threading Accretive Content across Scientific Papers

Luke S. Snyder, Jeffrey Heer

We introduce idea traces, a novel thread-based representation of accretive content across scientific papers. Rather than capturing fixed themes from papers, idea traces surface sim…

ThinkBooster: A Unified Framework for Seamless Test-Time Scaling of LLM Reasoning

Vladislav Smirnov, Chieu Nguyen, Sergey Senichev +14

Test-time compute (TTC) scaling has emerged as a powerful paradigm for improving large language model (LLM) reasoning by allocating additional compute during inference, e.g., via m…

Efficient Test-Time Inference via Deterministic Exploration of Truncated Decoding Trees

Xueyan Li, Johannes Zenn, Ekaterina Fadeeva +3

Self-consistency boosts inference-time performance by sampling multiple reasoning traces in parallel and voting. However, in constrained domains like math and code, this strategy i…

A Head to Predict and a Head to Question: Pre-trained Uncertainty Quantification Heads for Hallucination Detection in LLM Outputs

Artem Shelmanov, Ekaterina Fadeeva, Akim Tsvigun +9

Large Language Models (LLMs) have the tendency to hallucinate, i.e., to sporadically generate false or fabricated information. This presents a major challenge, as hallucinations of…

Faithfulness-Aware Uncertainty Quantification for Fact-Checking the Output of Retrieval Augmented Generation

Ekaterina Fadeeva, Aleksandr Rubashevskii, Dzianis Piatrashyn +7

Large Language Models (LLMs) enhanced with retrieval, an approach known as Retrieval-Augmented Generation (RAG), have achieved strong performance in open-domain question answering.…
