Normalize by sample mean of gradient norms

Specification

Alias: none

Argument(s): none

Description

For each reponse function $f_i$, normalize its gradient data by the mean $m_i$ of the gradient two-norms taken across samples $ j=1,...,J $:

\[ m_i = \frac{1}{J} \sum_{j=1}^{J}{\| \nabla^j f_i \|_2} \]
