Detailed Documentation

The BCI 2003 Brain-Computer Interface Competition centered on motor imagery applications for EEG data analysis, specifically utilizing the data3 dataset. Participants were required to implement advanced signal processing techniques including bandpass filtering (typically 8-30 Hz for mu/beta rhythms) and artifact removal algorithms before applying feature extraction methods such as Common Spatial Patterns (CSP) for optimal signal separation. Machine learning classifiers like Support Vector Machines (SVM) or Linear Discriminant Analysis (LDA) were commonly employed to distinguish between left/right hand motor imagery tasks with accuracy metrics serving as key evaluation criteria. The competition fostered innovation in real-time BCI systems through standardized MATLAB/Python implementations, advancing feature selection algorithms and adaptive thresholding techniques for improved signal classification performance.
