Sažetak
The problem of data clustering on the unit circle is considered in this paper. For that purpose, the metric on the unit circle is introduced and the problem is reduced to a one-dimensional center-based clustering problem. For solving this problem, an efficient method is proposed. The method is illustrated on seismic activity data from a wider area of the town of Dubrovnik in the Republic of Croatia since 1973. In this way, the moments in the year with most intensive seismic activity in this area are detected.
