Why does ALPF generator rely on high-frequency components of features?

[WesternTrail]

The purpose of ALPF generator is to generate a low pass filter, which allows the low frequency part of the features to pass through. Why does it rely on high frequency instead?

Thanks for your interest！The purpose of the Adaptive Low-Pass Filter (ALPF) generator is to create a low-pass filter that allows the low-frequency components of the features to pass through while attenuating the high-frequency components. The reason it relies on high-frequency information is not to pass it through but to identify and reduce those high-frequency elements that may cause intra-class inconsistency during the feature fusion process.
