Leveraging differential k-forms in Rn for efficient and interpretable geometric representation learning without message passing.
摘要
The paper introduces a novel approach to geometric deep learning using simplicial complexes embedded in Rn. By leveraging differential k-forms, the method offers interpretability and efficiency without the need for message passing. The content is structured as follows:
- Abstract: Introduces the concept of geometric deep learning and the limitations of existing methods.
- Introduction: Discusses the scope of geometric deep learning and the predominant paradigm of message passing.
- Background: Provides an overview of abstract simplicial complexes, affine embeddings, chains, cochains, and differential forms in Rn.
- Neural k-Forms and Integration Matrices: Details the concept of neural k-forms, integration matrices, scaling functions, integration process, and universal approximation theorem.
- Architecture: Explains how embedded chain data is transformed into integration matrices and fed into a readout layer for classification tasks.
- Experiments and Examples: Presents experiments on synthetic path classification, surface classification, and real-world graph datasets with comparisons to state-of-the-art models.
- Discussion: Summarizes the findings, limitations, outlook for future work, acknowledgments, and references.
