of values: [1, 1, 2, 5, 9, 10, 13, 15]. Its Haar wavelet transform is illustrated by the following table:

gorithms [11, 16, 9, 7, 14]. Such techniques rely on the assumption that normal points belong to large clusters while outliers [...] return a ranked list of potential outliers and limit the number of parameters to be specified [16, 9, 5]. Let us note that [5] proposes to reduce or to avoid given parameter to the clustering algorithm …
