WebDec 12, 2014 · The short answer appears to be Yes: there is some evidence that upsampling of the minority class and/or downsampling of the majority class in a training set can somewhat improve out-of-sample AUC (area under the ROC curve, a threshold-independent metric) even on the unaltered, unbalanced data distribution. With that said, … WebChroma resampling consists of these operations: Downsample — Reduces the bandwidth required for transmission or storage of a signal. You can prevent aliasing by applying a lowpass filter to bandlimit the input signal. Upsample — Expands the bandwidth of the signal. This block performs interpolation to approximate the missing chrominance values.
