Multi-Round Human-AI Collaboration with User-Specified Requirements

Summary

A new framework for multi-round conversational AI collaboration ensures reliable improvement in human decision quality, particularly for high-stakes scenarios. This human-centric approach is guided by two principles: counterfactual harm, which prevents AI from undermining human strengths, and complementarity, where AI adds value in areas prone to human error. These concepts are formalized through user-defined rules, allowing users to specify harm and complementarity for their specific tasks. The framework introduces an online, distribution-free algorithm with finite sample guarantees that enforces these user-specified constraints throughout the collaboration. Evaluations across an LLM-simulated medical diagnostic task and a human crowdsourcing pictorial reasoning task demonstrate that the online procedure maintains prescribed violation rates for counterfactual harm and complementarity, even with nonstationary interaction dynamics. Adjusting these constraints predictably shifts human accuracy, confirming their utility in steering collaboration towards better decision quality without modeling human behavior.

Key takeaway

For research scientists developing conversational AI for high-stakes decisions, you should consider integrating user-defined rules for counterfactual harm and complementarity into your collaboration frameworks. This approach offers practical levers to steer multi-round human-AI interactions toward improved decision quality without needing to explicitly model or constrain human behavior, ensuring AI reliably augments human capabilities.

Key insights

A human-centric AI collaboration framework uses user-defined rules to ensure AI complements human strengths and mitigates weaknesses.

Principles

• Counterfactual harm: AI must not undermine human strengths.
• Complementarity: AI must add value where humans err.

Method

An online, distribution-free algorithm enforces user-specified counterfactual harm and complementarity constraints over multi-round human-AI collaboration dynamics, with finite sample guarantees.

In practice

• Define task-specific harm and complementarity rules.
• Adjust constraints to predictably shift human accuracy.
