Summary

The paper introduces a novel decoding strategy termed "self-consistency" to enhance chain-of-thought prompting in language models, particularly for complex reasoning tasks. This method involves sampling a diverse array of reasoning paths and then selecting the most consistent answer by marginalizing these paths, leading to improved performance on arithmetic and commonsense reasoning benchmarks. Self-consistency achieves state-of-the-art results with models like PaLM-540B and GPT-3, offering robustness in reasoning by accommodating multiple valid approaches without needing additional training or human annotation. However, it requires more computation and is applicable only to problems with fixed answer sets, occasionally generating incorrect reasoning paths.
