New APTS method boosts LLM solution diversity by probing intermediate reasoning

Researchers have developed a new method called Answer Probing-Guided Tree Search (APTS) to encourage Large Language Models (LLMs) to generate more diverse solutions. Traditional methods struggle to differentiate truly distinct solution paths due to reliance on semantic embeddings that can be misled by linguistic similarities. APTS addresses this by probing LLMs for potential answers from intermediate reasoning steps. The hidden states of these probed answers are found to be more effective at distinguishing unique solution paths, with their perplexity serving as a proxy for reasoning correctness. Experiments on reasoning tasks with two LLMs demonstrated APTS's ability to consistently improve solution diversity and robustness. AI

IMPACT Enhances LLM capabilities in generating diverse solutions for complex tasks like code generation and drug discovery.
