ChebMixer: Efficient Graph Representation Learning with MLP Mixer

no code implementations25 Mar 2024 Xiaoyan Kui, Haonan Yan, Qinsong Li, Liming Chen, Beiji Zou

In this paper, we present a novel architecture named ChebMixer, a newly graph MLP Mixer that uses fast Chebyshev polynomials-based spectral filtering to extract a sequence of tokens.

Efficient Deformable Shape Correspondence via Multiscale Spectral Manifold Wavelets Preservation

no code implementations CVPR 2021 Ling Hu, Qinsong Li, Shengjun Liu, Xinru Liu

The functional map framework has proven to be extremely effective for representing dense correspondences between deformable shapes.

Shape correspondence using anisotropic Chebyshev spectral CNNs

no code implementations CVPR 2020 Qinsong Li, Shengjun Liu, Ling Hu, Xinru Liu

Rather than using fixed oriented kernels in the spatial domain in previous CNNs, in our framework, the kernels are learned by spectral filtering, based on the eigen-decompositions of multiple Anisotropic Laplace-Beltrami Operators.
