This skill enables the implementation and manipulation of Sheaf Neural Networks (SNNs) by generalizing standard graph Laplacians with vector spaces (stalks) and linear maps (restriction maps). It facilitates distributed consensus through sheaf diffusion, harmonic extensions for boundary value problems, and spectral clustering on sheaf sections. It is particularly effective for modeling heterophilic graph data where neighboring nodes maintain distinct representations or for implementing decentralized optimization strategies in complex topological structures.
