From: Detecting alpha spindle events in EEG time series using adaptive autoregressive models
A plot comparing expert-labeled alpha spindles with alpha spindles labeled by the SDAR algorithm. The algorithmic labelings are shown in light blue, while the start and end event codes (in green and red, respectively) denote the expert-labeled regions. (Top). An example where the algorithm labels a slightly narrower region as alpha spindle when compared to the expert. This minor timing difference will generate False Negative errors if no fuzzy window parameter is used. (Bottom). An example where the algorithm over-estimates the alpha-spindle region. This will generate False Positive errors, which can be accounted for if a fuzzy window parameter is used.
