q2 · i? · associational · r1

MRMR feature-importance analysis over the 84-feature stage-classification dataset, with the top 20 channel-band features ranked (Fig. 7). The authors note the high-weight regions and bands align with the bands emphasized in their spectral analysis.

"The relative PSD in the alpha band in the occipital lobe was assigned the highest categorization weight, followed by the relative PSD in the gamma, high-beta, and theta bands in the frontal lobe"

• Random Forest and SHAP analyses identify Gamma and Beta band power at temporal and frontal channels (T3, P3, F7, T4, T4, F8, F7) as the most critical features for EEG familiarity classification — related
• Relative PSD shows stage- and task-specific band patterns, including higher high-beta in Stage 3 of labs and quizzes — related
• Familiarity recognition is represented by a distributed multivariate spatial-spectral pattern rather than localized single-feature shifts, necessitating multivariate machine learning — related
