How to compute similarity between two signals?
Similarity in energy (or power if different lengths): Square the two signals and sum each (and divide by signal length for power). (Since the signals were detrended, this should be signal variance.) Then subtract and take absolute value for a measure of signal variance similarity.
Is basically used to find the similarity between the signals?
Cross-correlation is a measure of similarity between two signals.
What is similarity measures for binary data?
The following similarity measures are available for binary data: Russel and Rao. This is a binary version of the inner (dot) product. Equal weight is given to matches and nonmatches.
