Challenge: Large Language Models (LLMs) are a widely-used decoding strategy that relies on the plurality voting rule, which focuses on the most frequent answer while overlooking all other minority responses.
Approach: They propose to incorporate a ‘reflective mirror’ into the self-ensemble decoding process and enables LLMs to critically examine inconsistencies among multiple generations.
Outcome: The proposed method incorporates a ‘reflective mirror’ into the self-ensemble decoding process and enables LLMs to critically examine inconsistencies among multiple generations.

Mirror: Multiple-perspective Self-Reflection Method for Knowledge-rich Reasoning (2024.acl-long)

Copied to clipboard

Challenge: Large language models (LLMs) struggle with knowledge-rich problems without external resources.
Approach: They propose a Multiple-perspective self-reflection method that allows LLMs to reflect from multiple-perceptive clues, achieved through a heuristic interaction between a Navigator and a Reasoner.
Outcome: The proposed method is superior to other self-reflection methods on five reasoning datasets.
Confidence Improves Self-Consistency in LLMs (2025.findings-acl)

Copied to clipboard

Challenge: Modern large language models (LLMs) demonstrate strong reasoning capabilities, driven in part by their capacity to generate a sequence of intermediate reasoning steps that lead them toward a final answer.
Approach: They propose a method that performs a weighted majority vote based on confidence scores obtained directly from the model.
Outcome: The proposed method outperforms self-consistency on nine models and four datasets, reducing the required number of reasoning paths by over 40% on average.

Challenge: Conventional calibration methods treat answer correctness as binary and do not work for long-form generation where an answer can be partially correct.
Approach: They propose a framework where correctness of LLMs' responses and associated confidence levels are treated as distributions across a range of scores.
Outcome: The proposed framework treats the correctness of the LLMs’ responses and their associated confidence levels as distributions across a range of scores.
