Apr 5, 2025 04/05/25	OpenEquivariance was accepted to SIAM ACDA 2025! See you in Montréal.
Jan 26, 2025 01/26/25	Austin Glover and I are thrilled to announce OpenEquivariance, a fast kernel generator for rotation equivariant deep neural networks. These machine learning models rotate their predictions in a compatible way when the input (a point cloud) rotates. Read it here.
Sep 25, 2024 09/25/24	Beheshteh Rakhshan and I, along with Osman Asif Malik and Guillaume Rabusseau, worked on this paper on sketching tensor train core chains. It was just accepted as a poster to NeurIPS 2024.
