(the predicted and true clusterings, respectively) that are in the same cluster for both clusterings. The metric is symmetric, therefore swapping :math:`U` and :math:`V` yields the same rand score. This clustering metric is an extrinsic measure, because it requires ground truth clustering la...

Codoping of Al and P effectively dissolves the clustering and probably causes the coordination consisting of codopant oxisides (solvation shell), while that of F does not change the absorption and fluorescence properties of Ce doped glass due to Si-F covalent bonding formation. Preparation ...
