WebRobustScaler and QuantileTransformer are robust to outliers in the sense that adding or removing outliers in the training set will yield approximately the same transformation. But contrary to RobustScaler , QuantileTransformer will also automatically collapse any outlier by setting them to the a priori defined range boundaries (0 and 1). WebMar 29, 2024 · Both of them are sensitive to outliers as sklearn itself states. But I can't seem to get RobustScaler. I've read people saying that it reduces the effect of outliers in the distribution, so if one considered the outliers shouldn't have an effect on the data, one should use RobustScaler.
