Risk-Aware Selective Multimodal Driver Monitoring with Driver-State World Modeling
Summary
A novel cost-aware selective inference framework is proposed for deployable multimodal driver monitoring in automated vehicles, addressing the need for low-latency inference and safe decisions under uncertain driver states. The core system is a lightweight RGB-physiological student model, combining in-cabin visual observations with window-level heart rate (HR) and electrodermal activity (EDA) signals. A learned gate determines whether to accept a fast prediction or abstain for safety intervention. The system also incorporates a compact driver-state world modeling module to estimate future fast-model errors and system-level action costs. On scenario-induced driver-demand recognition, the RGB-physiological student achieved 0.7440 Macro-F1 and 0.9099 balanced accuracy with 11.39M parameters and 3.08ms inference latency. This cost-aware selective inference reduced unsafe false negatives from 17.37% to approximately 5%.
Key takeaway
For Machine Learning Engineers developing driver monitoring systems in automated vehicles, prioritize integrating multimodal data and risk-aware selective inference. Your designs should incorporate lightweight RGB-physiological models with learned abstention gates to achieve low-latency, high-accuracy predictions while significantly reducing unsafe false negatives from 17.37% to around 5%. Consider predictive driver-state world modeling to enhance proactive safety interventions and improve overall system reliability.
