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.
