Metric and algorithm for similarity between two temporal event sequences calculation
(КПІ ім. Ігоря Сікорського, 2017) Nikolaiev, S.
In several data analysis applications on temporal events flows, the problem of measuring “similarity” of these sequences arises. There are many different definitions of event sequences but in this paper under the term “sequence of events” the ordered array of the event occurrence times will be understood. In this paper the metric and procedure for similarity calculation between two ordered event sequences is presented. The procedure as the output returns measure of two event flows similarity and set of corresponding indices pairs which represent the mapping of the events between the input sequences.
