mean_gradient

Normalize by sample mean of gradient norms

Specification

• Alias: None

• Arguments: 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 $j=1,...,J$ :

$$m_i=\frac{1}{J}\sum _{j=1}^J\Vert {\mathrm{\nabla }}^j{f}_i{\Vert }_2$$
