Clustering techniques for functional data are reviewed. Four groups of clustering algorithms for functional data are … defined by filtering methods which first approximate the curves into a finite basis of functions and second perform clustering … using the basis expansion coefficients. The third groups is composed of methods which perform simultaneously dimensionality …
