GrokFormer parameterizes graph spectral filters as Fourier series over higher-order Laplacian spectra, achieving state-of-the-art accuracy on many node and graph classification tasks.
However, polynomial filter of BernNet is difficult to fit these filters, especially other complex filters beyond low-pass and high-pass filters
