Morlet wavelet transform was employed for calculating EEG features to determine the characteristics in the frequency domain. Additionally, Lyapunov exponents were utilized for the analysis of chaotic features, and significant EEG channels were identified from the obtained results of the wavelet transform. Using permutation importance, the impact of each feature on the performance of the classification model was assessed. In this evaluation, the Random Forest model stood out in overall performance, showing the highest accuracy (0.7614), precision (0.7546), and F1 score (0.793) compared to other models. Furthermore, the Naive Bayes model achieved the highest sensitivity (0.8662) in detecting positive instances. © 2024 IEEE.trinfo:eu-repo/semantics/closedAccessAlzheimer's DiseaseClassificationElectroencephalographyMachine LearningConference Object10.1109/SIU61531.2024.10600949142-s2.0-85200897216N/A
