WebDec 14, 2024 · Reading through the code it first converts the signal to frequency domain, then discards the middle half of the frequencies (i.e. second and third quarters), then inverse-transform back to time domain. Therefore it is trying to keep the lowest and highest frequencies of the signal. 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, …
