RT info:eu-repo/semantics/article T1 Time series clustering using the the total variation distance with applications in Oceanography A1 Álvarez Esteban, Pedro César A1 Euán, C. A1 Ortega, J. K1 Oceanografía - Estadística AB A time series clustering algorithm based on the use of the total variation distancebetween normalized spectra as a measure of dissimilarity is proposed in this work.The oscillatory behavior of the series is thus considered the central characteristic forclassi cation purposes. The proposed algorithm is compared to several other methodswhich are also based on features extracted from the original series and the results showthat its performance is comparable to the best methods available and in some tests itoutperforms the rest. As an application the algorithm is used to determine stationaryperiods for random sea waves, both in simulations and on a real data set, a problemin which changes between stationary sea states are usually slow.
