This paper introduces a new type of spherical CNN based on spin-weight spherical functions that were introduced in physics for gravitational waves study. The exploited spin-weighted spherical harmonics, as generalizations of standard spherical harmonics, are more expressive and allow for working with inputs and outputs that are vector fields. Good experimental results illustrate the advantage of the proposed spherical CNN over traditional ones. The new experimental results added in the authors' response nicely addressed reviewers' concerns and should be included in the paper.
