In recent years, evidence has emerged indicating that magnetic resonance imaging (MRI) brain scans provide valuable diagnostic information about Alzheimer’s disease. It has been shown that MRI brain scans are capable of both diagnosing Alzheimer’s disease itself at an early stage and...

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 … reduction of the curves and clustering, leading to functional representation of data depending on clusters. The last group …
