2nd Annual TAG in Machine Learning
A Workshop at the 40th International Conference on Machine Learning , Honolulu, HI, July 28th, 2023 in Room 317B
Call for Papers
Much of the data that is fueling current rapid advances in machine learning is high dimensional, structurally complex, and strongly nonlinear. This poses challenges for researcher intuition when they ask (i) how and why current algorithms work and (ii) what tools will lead to the next big break-though. Mathematicians working in topology, algebra, and geometry have more than a hundred years worth of finely-developed machinery whose purpose is to give structure to, help build intuition about, and generally better understand spaces and structures beyond those that we can naturally understand. Following on the success of the first TAG-ML workshop in 2022, this workshop will showcase work which brings methods from topology, algebra, and geometry and uses them to help answer challenging questions in machine learning. Topics include mathematical machine learning, explainability, training schemes, novel algorithms, performance metrics, and performance guarantees. All accepted full length papers will be included in an associated PMLR volume. We are also offering the option of submitting non-archival extended abstracts.

Paper Length and Format
The full paper submission must be at most 8 pages in length (excluding references and supplementary materials) and double blind. We will be following the ICML general conference submission criteria for papers - for details please see: ICML Call For Papers. As a note the reviewers will not be required to review the supplementary materials so make sure that your paper is self-contained. For the extended non-archieval abstracts please use the same template but limit the submission to 4 pages inclusive of references. There will be an option on the submission site to differentiate full papers and extended abstracts.
(NEW) Topological Deep Learning Challenge
The purpose of this challenge is to foster reproducible research in Topological Deep Learning by crowdsourcing the open-source implementation of neural networks on topological domains. Participants are asked to contribute code for a previously existing Topological Neural Network (TNN) and train it on a benchmark dataset.
Implementations are built using TopoModelX, a Python package for deep learning on topological domains. Each submission takes the form of a Pull Request to TopoModelX containing the necessary code for implementing a TNN from the literature. The implementation leverages the coding infrastructure and building blocks from TopoModelX.
Please see the challenge website for more information: https://pyt-team.github.io/topomodelx/challenge/index.html - the deadline for submissions is July 13th, 20023 at 16:59 PST.

Dr. Henry Kvinge
Pacific Northwest National Laboratory
University of Washington
Henry Kvinge received his PhD in Mathematics from UC Davis where his research focused on the intersection of representation theory, algebraic combinatorics, and category theory. After two years as a postdoc in the Department of Mathematics at Colorado State University where he worked on the compressive sensing-based algorithms underlying single-pixel cameras, he joined PNNL as a senior data scientist. These days his work focuses on leveraging ideas from geometry, and representation theory to build more robust and adaptive deep learning models and frameworks.
Dr. Tim Doster
Pacific Northwest National Laboratory
Tim Doster is a Senior Data Scientist at the Pacific Northwest National Laboratory. He received the B.S. degree in computational mathematics from the Rochester Institute of Technology in 2008 and the Ph.D. degree in applied mathematics and scientific computing from the University of Maryland, College Park, in 2014. From 2014 to 2016, he was a Jerome and Isabella Karle Distinguished Scholar Fellow before becoming a Permanent Research Scientist in the Applied Optics division with the U.S. Naval Research Laboratory. During his time with the U.S. Naval Research Laboratory he won the prestigious DoD Laboratory University Collaboration Initiative (LUCI) grant.
