Fair channel ablation and cost-sensitive classification for EEG-based driver fatigue detection: engineering guidelines from real-world driving
Wearable EEG fatigue monitoring requires principled channel selection and robust classification under class imbalance. We introduce a fair per-channel-only ablation protocol for binary fatigue detection—alert (KSS ≤ 6) vs. fatigue (KSS ≥ 7)— applied to 64-channel EEG from 99 real-driving participants (534 trials).
