New HCRA Framework Boosts Human-AI Collaboration via Reflective Learning
Addressing over- and under-reliance on AI, HCRA uses linguistic feedback to align decisions.
A new paper from researchers at the University of Piraeus introduces the Human-Centric Reflective Architecture (HCRA), a framework designed to tackle persistent challenges in human-AI collaboration: over-reliance on AI recommendations, under-reliance, and poor calibration to human expectations. Current AI systems often produce outputs misaligned with human preferences, especially in safety-critical contexts. HCRA addresses this by framing collaborative decision-making as a stochastic game between a human player and an AI agent, where both interact iteratively.
The core innovation lies in integrating human-calibrated models with reinforcement learning agents that refine their recommendations through a reflective process using linguistic feedback from the human. This iterative cycle allows the AI to align its suggestions with the user's expectations and situational needs. Evaluation results demonstrate that HCRA significantly improves decision-making effectiveness and recommendation quality. The framework opens a path toward more trustworthy human-AI systems, with potential applications in healthcare, autonomous driving, and other high-stakes domains where alignment and calibration are critical.
- Models human-AI collaboration as a stochastic game to capture dynamic interactions.
