BSS-CCA#

This example uses a real EEG substrate with controlled broadband muscle-like contamination to illustrate reference-free BSS-CCA. The method separates components according to lagged temporal correlation, so broadband low-correlation components can be attenuated without a dedicated reference channel.

The controlled construction makes it possible to evaluate both artifact recovery and change outside the contaminated periods. Low lagged correlation is a selection heuristic, not an automatic artifact label.
