Intrinsic Regularity Detection in 3D Geometry [chapter]

Niloy J. Mitra, Alex Bronstein, Michael Bronstein

Geometric Deep Learning: Grids, Groups, Graphs, Geodesics, and Gauges [article]

Michael M. Bronstein, Joan Bruna, Taco Cohen, Petar Veličković
2021 arXiv   pre-print
learning is built from two simple algorithmic principles: first, the notion of representation or feature learning, whereby adapted, often hierarchical, features capture the appropriate notion of regularity for  ...  We hope that our perspective will make it easier both for newcomers and practitioners to navigate the field, and for researchers to synthesise novel architectures, as instances of our blueprint.  ...  For two-dimensional manifolds (surfaces), isometries can be intuitively understood as inelastic deformations that deform the manifold without 'stretching' or 'tearing' it.  ...

Aneeshan Sain, Ayan Kumar Bhunia, Yongxin Yang, Tao Xiang, Yi-Zhe Song
2021 arXiv   pre-print
Sketch-based image retrieval (SBIR) is a cross-modal matching problem which is typically solved by learning a joint embedding space where the semantic content shared between photo and sketch modalities  ...  Extensive experiments show that our style-agnostic model yields state-of-the-art performance for both category-level and instance-level SBIR.  ...  Most existing meta-learning methods [54, 46, 6] are designed for few-shot image classification and thus are suitable for our problem of meta-learning of a generalisable cross-modal disentanglement model  ...
