Detailed Description

This is the base clase for non-linearities used in deflation based ICA.

This class defines the interface of the nonlinearity g for deflation based FastICA. In order to implement the a real non-linearity the method get_correction_and_scale must be overwritten.

If the factor \(\mu\) defined in the parent class is \(\ge 1.0\), than the normal implementation will be used, if the value is positive but \(\le 1.0\) then the stabelized variant of the algorithm is used.
