Results
Band Power
- Subject specific frequency bands determined
- Frequency bands varied between 9-14 Hz (alpha-band) and 18-26 Hz
(beta-band)
Band Power Accuracy
On-line classification
~80% accuracy for all 3
subjects
Adaptive Autoregressive Parameters
- Minimum of 6 coefficients used to reproduce the power spectral density
- All 3 subjects reached 85-95% accuracy within 7 sessions
Common Spatial Patterns
- Electrodes weighted according to importance to the discrimination task
- Best classification accuracy using 27 or 56 electrodes for 3 subjects
- Accuracies between 90 and 100%
