WebDec 11, 2024 · Viewed 653 times. 2. I'm reading the paper Convolutional Neural Networks on Graphs with Fast Localized Spectral Filtering and find it difficult to understand the motivation for using Chebyshev polynomials. With localized kernels, g θ ( Λ) = ∑ k = 0 K − 1 θ k Λ k, and the convolution U g θ ( Λ) U T f becomes ∑ k = 0 K − 1 θ k L k f.
