This morning it occurred to me that the problems we’re having with our equation \begin{align}S^2 Z^2 S^2 – S C S = \lambda (Z^{-1} – I)\label{main}\tag{1}\end{align} are due to the regularizer we use, $\|Z – I\|_F^2$. This regularizer makes the default behavior of the feedforward connections passing the input directly to the output. But it’s…
