Patterns with Equal Values in Permutation Entropy: Do They Really Matter for Biosignal Classification?

Table 4

Final percentage of equal values in each database, specifically for . The first column, baseline, corresponds to the level found right after signal acquisition, and the rest of the columns correspond to the resulting percentage after merging randomly synthetic equal values and those found initially in the records.

	Baseline	5%	10%	15%	20%	25%
EEG	5.35%	9.67%	13.64%	17.63%	21.65%	25.82%
Temp	18.02%	22.12%	25.12%	28.42%	31.79%	32.34%
RR	37.10%	41.52%	43.24%	44.83%	46.67%	48.42%
CGM	31.00%	33.87%	35.70%	38.91%	40.28%	43.05%
