Initial commit
Initial commit, setting up the laplace approximation for a student t
Added some comments
Got most of laplace approximation working
Trying to 'debug'
got an idea of how to implement! written in docs
following naming convention better, lots of inverses which should be able to get rid of one or two, unsure if it works
Just breaking some things...
Worked out in terms of W, needs gradients implementing
Changing definitions again...
Seemed to be working, now its not
Working laplace, just needs predictive values
Added predicted values for student t, works well
Tidying up
Still working on rasmussen, link function needs vectorizing I think
Fixed broadcasting bug, rasm now appears to work
Got the mode finding without computing Ki
Added timing and realised mdot can be faster as its almost always a diagonal matrix its multiplying with
Stabalised most of the algorithm (apart from the end inversion which is impossible)
Fixed laplace approximation and made more numerically stable with cholesky decompositions, and commented
