function [co] = IApprCorrEntr_initialization(mult)
%Initialization of the approximate correntropy independence measure estimator. The estimated quantity is computed according to the relation: I(y^1,y^2) = max(|CCorrEntr(y^1,y^2)|,|CCorrEntr(-y^1,y^2)|), where CCorrEntr denotes centered correntropy.
%   1)The estimator is treated as a cost object (co). 
%   2)We use the naming convention 'I<name>_initialization' to ease embedding new mutual information estimation methods.
%   3)This is a meta method: the centered correntropy estimator can be arbitrary.
%   mult: is a multiplicative constant relevant (needed) in the estimation; '=1' means yes, '=0' no.
%   co: object (structure).
