ott.geometry.regularizers.STVS.prox_dual# STVS.prox_dual(v, tau=1.0)# Proximal operator of the convex conjugate. Uses Moreau’s decomposition: \[v = \prox_{\tau f} \left(v\right) + \tau \prox_{\frac{1}{\tau} f^*} \left(\frac{v}{\tau}\right)\] Parameters: v (Array) – Array of shape [d,]. tau (float) – Positive weight. Return type: Array Returns: The prox dual of v.
