meaning of variables in RESPONSE_NORM type edge

[neuralix]

Hi.
how i should treat {k, n} in the equation in [1] using your variables in net-model file?
(I understand that the alpha is 'add_scale' and beta is 'pow_scale')

[1] '3.3 Local Response Normalization' in Krizhevsky et al.'s paper.

And now I found the assertion error mentioned before is occur in RESOPONSE_NORM edge.

Specify k/n as frac_of_filters_response_norm.
