Random Forest Model Hits 92.49% Accuracy in EEG Eye-State Detection
Researchers paired interquartile-range clipping for outlier removal with a random forest classifier on the UCI machine learning repository's EEG-Eye-State dataset, classifying eyes-open versus eyes-closed at 92.49% accuracy with a ROC-AUC of 0.9791. Cross-validation put mean accuracy at 92.86%. The authors present the pipeline as a stable, interpretable option for BCI uses such as drowsiness monitoring and assistive technology.
