%description
An implementation of a clustering algorithm for functional data based on
adaptive density peak detection technique, in which the density is
estimated by functional k-nearest neighbor density estimation based on a
proposed semi-metric between functions. The proposed functional data
clustering algorithm is computationally fast since it does not need
iterative process. (Alex Rodriguez and Alessandro Laio (2014)
