Linear versus non-linear transformations
Linear transformation
F(x)
of a raw data vector
x
such that
F
is a linear function of
x
. E.g.
F(x)=2x+1
Non-linear transformations
F(x)
of a raw data vector
x
such that
F
is a non-linear function of
x
. E.g.
F(x)=1(1+e-x.c)
Other non-linear transformations
The logarithmic function,
F(x)=log10x.
