Group-invariant max filtering

no code implementations27 May 2022 Jameson Cahill, Joseph W. Iverson, Dustin G. Mixon, Daniel Packer

Given a real inner product space $V$ and a group $G$ of linear isometries, we construct a family of $G$-invariant real-valued functions on $V$ that we call max filters.

Lie PCA: Density estimation for symmetric manifolds

no code implementations10 Aug 2020 Jameson Cahill, Dustin G. Mixon, Hans Parshall

In particular, we use a spectral method to approximate the Lie algebra corresponding to the symmetry group of the underlying manifold.
