Analysis of gradient descent dynamics for this architecture in the linear case reveals the role of the internal linear layers in leading to faster decay of a "collective weight variable" incorporating all layers, and the role of weight decay in breaking degeneracies and thus driving convergence along directions in which no decay would occur in its absence.

Our non-detections place a limit on the covering factor of such optically-thick gas around M31 to $f_c < 0. 051$ (at 90\% confidence) for $\rho \leq R_{\rm vir}$.
