Introducing convolution over tangent bundles of Riemann manifolds, leading to novel architectures for processing vector fields on manifolds.
要約
The content introduces a novel convolution operation over the tangent bundle of Riemann manifolds using the Connection Laplacian operator. It defines tangent bundle filters and neural networks based on this operation, providing a spectral representation that generalizes existing filters. A discretization procedure is introduced to make these continuous architectures implementable, converging to sheaf neural networks. The effectiveness of the proposed architecture is numerically evaluated on various learning tasks. The paper discusses the development of deep learning techniques and their applications in various fields, emphasizing the importance of processing data defined on irregular domains like manifolds. It also explores related works in manifold learning and introduces cellular sheaves as a mathematical structure for approximating connection Laplacians over manifolds.
