Researchers have developed a new framework called Human-Feedback-Guided Multi-Agent Inverse Reinforcement Learning (HFG-MAIRL) to better model human driving behavior in mixed traffic scenarios. This framework addresses limitations in existing methods by explicitly modeling interactions between vehicles within a localized Markov game, rather than treating other cars as mere obstacles. It also incorporates human feedback, such as driver emotion labels, as ordinal preferences to refine reward recovery. Experiments on the AIDE dataset demonstrated that HFG-MAIRL outperforms traditional Inverse Reinforcement Learning baselines in decision modeling and generates interpretable, feedback-aligned reward patterns.
