Overview of the Data Analysis Pipeline.
<p>The pipeline consists of four main stages: (1) Conversion of raw optical signals into relative changes in HbO concentration using Modified Beer-Lambert Law; (2) Preprocessing of HbO signals through Correlation-Based Signal Improvement (CBSI) and a Butterworth bandpass filter; (3) Feature Ex...

| Summary: | <p>The pipeline consists of four main stages: (1) Conversion of raw optical signals into relative changes in HbO concentration using Modified Beer-Lambert Law; (2) Preprocessing of HbO signals through Correlation-Based Signal Improvement (CBSI) and a Butterworth bandpass filter; (3) Feature Extraction, where hemodynamic time-domain features are extracted(e. g. mean, variance, kurtosis…); and (4) Classification through machine learning algorithms which include k-Nearest Neighbors (KNN), Ensemble, and Support Vector Machine (SVM).</p> |
