From EEG signal via dendrograms to PUDHS values—an illustration. A simple example showing a time series of 3 dendrograms (up) from three 1 s widows. Each dendrogram has 19 branches corresponding to the 19 electrodes. lower dendrogram was constructed by pairwise distances of 57 segments of EEG data meaning (3 windows × 19 segments in each window). PUDHS values are calculated by counting how many branches sum of 2-adic expansion is lower than threshold (blue thick horizontal line at the bottom dendrogram).
