TAG in Pattern Recognition with Applications

A workshop at the Computer Vision and Pattern Recognition (CVPR) in Vancouver, Canada on June 18th, 2023.

Call for Papers

Much of the data that is fueling the current rapid advances in mainstream data science, computer vision, and pattern recognition is high-dimensional, abundant, and relatively noise-free. However, this poses challenges in many application domains in terms of building algorithms that can capture meaningful structure from limited data and also building analytical techniques that help to understand what that structure means. Mathematicians working in topology, algebra, and geometry have more than a century’s worth of finely-developed machinery whose purpose is to give structure to, help build intuition about, and generally better understand patterns in complex data. We welcome submissions that utilize frameworks, techniques, and concepts rooted in one or more of topology, algebra, and geometry that consider a pattern recognition challenge faced in an application domain. All submitted works should include at least one real-world use-case. This session is an opportunity for researchers building robust, mathematically principled methods to present and publish work on real-world problems in pattern recognition for which standard off-the-shelf techniques do not work.

Keynotes

Dr. Nina Miolane

University of California Santa Barbara

A Survey of Topological Neural Networks

Topological Neural Networks (TNNs) are deep learning architectures that process signals defined on topological domains, such as hypergraphs and cellular complexes -- hence generalizing Graph Neural Networks. The additional flexibility and expressivity of TNN architectures permits the representation and processing of complex natural systems such as proteins, neural activity, and many-body physical systems. This talk synthesizes the recent TNN literature using a single unifying notation and graphical summaries and sheds light on existing challenges and exciting opportunities for future development.

Nina Miolane is an Assistant Professor at UCSB. She received her Ph.D. in Computer Science from INRIA (France) in collaboration with Stanford University. Nina worked as a postdoc at Stanford, and as a software engineer in the Silicon Valley. At UCSB, Nina’s research focuses on AI for biological shape analysis: she investigates how the shapes of proteins, cells, and organs relate to their biological functions, and how abnormal shape changes correlate with pathologies. Her team also co-develops Geomstats, an open-source software of geometric machine learning. Research fundings include a NIH R01 grant, the NSF SCALE MoDL. Nina was the recipient of the L'Oréal-Unesco for Women in Science Award and a winner of the C3.ai grand Covid-19 challenge.

Recognizing Rigid Patterns of Unlabeled Point Clouds

Rigid structures such as cars or any other solid objects are often represented by finite clouds of unlabeled points. The most natural equivalence on these point clouds is rigid motion or isometry that maintains all inter-point distances. Rigid patterns of point clouds can be fully identified only by complete isometry invariants (also called equivariant descriptors) that should have no false negatives (isometric clouds having different descriptions) and no false positives (non-isometric clouds with the same description). Noise in data motivates a search for invariants that are continuous under perturbations of points in a suitable metric. We propose a continuous and complete invariant for finite clouds of unlabeled points in any Euclidean space. For a fixed dimension, a new metric for this invariant is computable in a polynomial time in the number of points. The talk is based on the CVPR 2023 paper with Daniel Widdowson.

Prof Vitaliy Kurlin is a universal scientist, a mathematician by training, now leading the Data Science Theory and Applications group in the Materials Innovation Factory, Liverpool, UK. He completed a PhD in Geometry and Topology at Moscow State University in 2003 and held a Marie Curie International Incoming Fellowship in 2005-2007 and a Royal Academy of Engineering Industry Fellowship in 2021-2023. His group is developing a new area of Geometric Data Science whose key results include the Crystal Isometry Principle (NeurIPS 2022) and complete invariants of finite clouds of unlabeled points under Euclidean isometry (CVPR 2023), see details.
