20a02cc445 removed uncertain gp regression from the model __init__, since it's now
just a switch in the sparse GP

1d8104bcc2 general tidying in sparse_GP_regression
Have also made a small ampount of headway in
enabling heteroscedatic noise.

365d069ae8 saved a little computation by exploiting the symmetry of a matrix 2012-12-02 12:35:54 +00:00

1c60e50fed I think the gradients bug in the sparse GP model is due to Kmm being unstable to invert. REducing M in some of the examples really helps 2012-12-02 12:32:20 +00:00
