Quantitative biomedical signaling has potential for exposing abnormalities in HD patients. In this project, we attempted to explore biomedical signalling for HD diagnosis in high detail. we used a dataset collected at a clinic with 27 HD-positive patients, 36 controls, and 6 unknowns with EEG, ECG, and fNIRS. We first preprocessed the data and then presented a comprehensive feature extraction procedure for statistical, Hijorth, slope, wavelet, and power spectral features. We then applied several shallow machine learning techniques to classify HD-positives from controls. We found the highest accuracy was achieved by the Extremely Randomized Trees algorithm, with ROC AUC of 0.963 and accuracy of 91.353%. The results provide performance improvement over competing methodologies and also show promise for biomedical signals to prognose HD early.
