EEG-based familiarity prediction models require rigorous validation

Researchers have developed a method to benchmark machine learning and deep learning models for predicting cognitive familiarity using EEG data. The study highlights the critical need for trial-independent validation to avoid overestimating model performance, as standard cross-validation can lead to artificially high scores due to temporal leakage. Using a rigorous Group K-Fold validation, the peak performance for a CNN model dropped significantly, though it remained statistically above chance. The analysis also identified temporal and frontal Gamma and Beta oscillations as key biomarkers for familiarity. AI
