Abstract :
We consider the problem of subspace learning in the presence of interference and generalized Gaussian noise, two realistic scenarios for many applications. We also explore learning in the context of a non-Euclidean generalization of the Courant-Fisher minmax characterization. Implications for learned subspace properties in the presence of Laplacian noise are discussed as well.
