Let $\Upsilon_{\gamma,\beta}(y)$ be the shrinker defined in equation (Upsilon), and let $\mathsf{z}^{+}_{\gamma,\beta}$ and $\mathsf{z}^{-}_{\gamma,\beta}$ be the associated spectr…

Let $L$ be the Frobenius loss, and let $L_\infty(\eta\mid\mathbf{x})$ denote the asymptotic loss of a continuous singular-value shrinker $\eta$ at any signal singular-value vector…
