CAPS: Cascaded Adaptive Pairwise Selection for Efficient Parallel Reasoning
The article introduces CAPS, a new framework for efficient parallel reasoning in large language models. CAPS utilizes a cascaded adaptive pairwise selection method to optimize the verification process, reducing computational costs significantly. The framework has demonstrated superior performance on various reasoning benchmarks compared to existing methods.
- ▪CAPS stands for Cascaded Adaptive Pairwise Selection and aims to improve parallel reasoning efficiency.
- ▪The framework adapts the verification process along two axes: evidence and distribution.
- ▪CAPS has outperformed leading pairwise verifiers on 14 out of 20 reasoning benchmarks while using less computational resources.
