Computes the GP coefficients from the TAP/EP ones.
ogpajdgp;
ogpadjgp updates the OGP coefficients (w and C) from the
GLOBAL TAP/EP structure ep calculated within the online learning
routine.
This function serves as ``sanity check'' to compare the stability of the
iterative solution with the ``batch result'' which requires a matrix
inversion. The sum of absolute differences between the new (TAP/EP based)
and old (w,C) OGP parameters is displayed.
This function does not recompute the inverse of the Gram matrix.
Recomputing the inverse and adjusting the GP parameters proved to be
!EXTREMELY! unstable when det(net.KB) is small - which the case in
most practical situations when
using kernel methods.
