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 \(j=1,...,J\) :

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