RT @maurice_weiler: How to parameterize group equivariant CNNs? Our generalization of the famous Wigner-Eckart theorem from quantum mechanics to G-steerable (equivariant) convolution kernels answers this question in a quite general setting.

Inverse problems in spaces of measures

Inverse problems in spaces of measures

While the basic regularization theory of inverse problems is well-established in Hilbert spaces [22] and for linear problems in Banach spaces [34], recent interest focuses on specific ...

Some of our main results were the following: • the symmetrization theorem for kernels invariant under the action of a group (Theorem 4.4.3 on page 62); • the characterization of translation ...
