053ebbe2d4 t of the gradients are now working in the uncollapsed sparse GP: one
term still to do.

5f2c2a04f8 chenged a little of the notation in the sparse GP
This should allow easier implementation of het. noise

fe13d2c09a more skeletal work on the uncollapsed GP
None of the gradients work, but lots more things are in place

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

5f22bd00e6 made uncertain inputs a simple swith in the sparse GP class. This simplifies the inherritance structure 2012-12-03 18:35:05 +00:00

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

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
