| Feb 6, 2017 at 23:00 | comment | added | Wilmer Ariza | Yes there are, I had the code from Multi-Output GP from Alvarez and Lawrence(works great). However the promise of lower times is too much....In the code they implement: fn1 = @(x) sin(x) + 1e-7; fn2 = @(x) -sin(x) + 1e-7; y1 = fn1(x) + sqrt(1e-4)*randn(N,1); y2 = fn2(x) + sqrt(1e-4)*randn(N,1); if you change to cos or sin(fn1) in the second function the method stop working. If the frequency is incfeazse it will not converge. I think that there is an error in the likelihood. | |
| Feb 6, 2017 at 14:03 | comment | added | DeltaIV | to a first look, the methodology looks fine, even if IMO overcomplicated (there are simpler approaches to multivariate Gaussian processes). To tell you more I need to see what you did, i. e., you should post or link both the code with independent outputs, which ran ok, and the code with non-independent outputs, and see exactly what you mean by "failure". | |
| Feb 6, 2017 at 2:50 | comment | added | Wilmer Ariza | I am interested in know how can be correctly implemented because the code in the GitHub does not do what the paper claim. The GitHub has non-related outputs and as soon you relate the outputs it fails. The math looks ok. If you can give me your opinion about the method I will appreciate that. | |
