MACIE: Multi-Agent Causal Intelligence Explainer for Collective Behavior Understanding

Existing AI explanation tools fail in multi-agent systems: Current explainable AI methods struggle to explain decisions when multiple AI agents work together, particularly in attributing outcomes to individual agents or understanding how collective behavior emerges—a critical gap for safety-critical applications like autonomous vehicles or robotic teams.

MACIE can identify which agent caused which outcome: The framework achieved mean attribution scores (phi_i) of 5.07 with very low variation (standard deviation <0.05), meaning it can reliably pinpoint each agent's causal contribution to collective results, enabling accountability in multi-agent systems.

The system can measure "emergent intelligence" that exceeds individual contributions: MACIE detected positive emergence in cooperative tasks with synergy indices up to 0.461, quantifying how agents working together produce outcomes greater than the sum of individual actions—important for understanding whether AI teams are truly collaborating or just following independent rules.

Explanations can be translated into human-readable narratives: Beyond technical metrics, MACIE generates natural language explanations that synthesize causal insights, making multi-agent AI decisions understandable to non-technical stakeholders and regulators who need to audit AI system behavior.

The approach is computationally practical for real-world deployment: Processing explanations takes only 0.79 seconds per dataset on standard CPU hardware, suggesting MACIE could be integrated into actual multi-agent AI systems rather than remaining a theoretical tool.
