An example of the adaptive thresholding is τij = τ(ˆriiˆrjj) 1/2, for a given τ > 0 (2.3) where ˆrii is the ith diagonal element of Rb. This corresponds to applying the thresholding with parameter τ to the correlation matrix of Rb. Moreover, instead of the hard-thresholding, seedy bathroom wood paneling
