Improved Generalization Bound of Group Invariant / Equivariant Deep Networks via Quotient Feature Space

15 Oct 2019Akiyoshi SannaiMasaaki Imaizumi

A large number of group invariant (or equivariant) networks have succeeded in handling invariant data such as point clouds and graphs. However, generalization theory for the networks has not been well developed, because several essential factors for generalization theory, such as size and margin distribution, are not very suitable to explain invariance and equivariance...
