Hi @jastfkjg,
For a lot of the core functions we are following closely the matlab implementation (found here) so the references to the original research are directly applicable. The most comprehensive is Efficient Reinforcement Learning using Gaussian Processes, the PhD thesis by Marc Deisenroth.
The input - output covariance, cov[x, f(x) | m, S], refers to the covariance between an input to the GP model, x, and the model's output f(x). It's needed for long term predictions, and it's used in our pilco.propagate
function, and the corresponding Matlab function ( pred.m
and propagate.m
). If you want to see the math in more detail, see paragraph 2.3.3 of the thesis I linked above, with the final equation being 2.70.

I will try to figure it out, Thanks a lot.
