WebNov 17, 2016 · where δ i is a connectivity degree, i.e., the number of non-hydrogen atoms to which the ith non-hydrogen atom is bonded;m is the order of the connectivity index;k denotes the type of the fragment of the molecule, for example: path (p), cluster (c), and path-cluster (pc); andn m is the number of fragments of type k and order m. WebThe k-means algorithm divides a set of N samples (set X) into k disjoint clusters (set C) in terms of the descriptor space, each cluster described by the mean μj (j = 1 – k), of the sample in the cluster. The inertia score is the minimized results of the within-cluster sum-of-squares criterion by adjusting the mean position of each cluster. hurray overseas education consultant
