Function LOG_SCAT

Package

Short description

Usage

Input

    S (cell): A scattering transform.
    epsilon (real): An small constant added to each component of S in
    order to reduce contribution of noise (default 2^-20).

Output

    S (cell): The scattering transform with the logarithm applied to each 
       coefficient.

Description

    This function takes the logarithm of every signal component in a
    scattering transform, while preserving the network structure. A small
    additive constant is used to keep finite results. Note that this
    function may also take a single layer of the whole network as an
    argument, as it calls itself recursively layerwise.
