DerDerTransParTanH
- second derivative of transfer function
SYNOPSIS
double DerDerTransParTanH
(unit)
ARGUMENTS
UNIT
*unit
A pointer to a
UNIT
structure.
RETURNS
The output of
unit
as calculated using the
Value.Activation
field value.
FUNCTION
The return value is
(c1 * c2 * c2 * tanh (c2 * unit->Value.Activation2) / (cosh (c2 * unit->Value.Activation) ^2)
, where
c1
=
unit->TransFuncPar1
and
c2
=
unit->TransFuncPar2.
