New algorithm PP-LUCB uses LLMs and human audits to optimize service systems

A new research paper introduces PP-LUCB, an algorithm designed to optimize service systems by leveraging textual evidence, such as customer transcripts, to assess performance quality. Traditional methods struggle with the biases inherent in large language models (LLMs) used for automated scoring, while human audits are costly. PP-LUCB addresses this by combining LLM-generated scores with selective human audits, proving effective in reducing costs and correctly identifying optimal configurations. AI

IMPACT Optimizes service systems by reducing reliance on costly human audits and mitigating LLM biases in performance evaluation.

    Designing Service Systems from Textual Evidence

    arXiv:2603.10400v2 Announce Type: replace-cross Abstract: Designing service systems requires selecting among alternative configurations -- choosing the best chatbot variant, the optimal routing policy, or the most effective quality control procedure. In many service systems, the …
