ANALISIS KLASIFIKASI MODEL PENYAKIT PARKINSON DENGAN FITUR AKUSTIK YANG DIREPLIKASI MENGGUNAKAN METODE XGBOOST
Abstract
Parkinson’s disease is a neurodegenerative disorder characterized by the decline of motor and non-motor functions due to damage in dopamine-producing neurons. This study aims to develop a classification model for Parkinson’s disease based on acoustic features using the Extreme Gradient Boosting (XGBoost) algorithm. The dataset was obtained from Kaggle, consisting of 195 voice recordings with 24 acoustic features. Data preprocessing included normalization, feature selection using ANOVA F-test, and class balancing using the Synthetic Minority Oversampling Technique (SMOTE). The XGBoost model was trained and tested using an 80:20 train-test split. Evaluation results showed the model achieved an accuracy of 92%, with average precision, recall, and F1-score values of 0.93, 0.92, and 0.92, respectively. These findings indicate that XGBoost provides strong classification performance in detecting Parkinson’s disease based on patients’ voice features and holds promise for further development into AI-assisted diagnostic systems.
