WebThe figure gives the table of cumulative values of the class 1 classifications and the corresponding lift chart. The dashed line joining the points (0,0) to (24,12) is a reference … WebOur second integer spectral graph transform is achieved by introducing rounding operations within the spectral graph lifting structures proposed in Reference [34]. Hence, we transform it into an integer-to-integer graph wavelet transform. Using our proposed transforms mentioned above, we design a lossy-to-lossless extension to
