[R] Gaussian Process Classification R packages

[Damjan Krstajic]

Thank you Charles Berry for your kind reply. I don't see anything wrong with the word "struggling". I have spent several hours trying various R packages like kernlab and GPfit to use GP to create a binary classification model which produces a prediction interval for each sample. I have been struggling because with all of them you may create a GP classification model but it only produces a single prediction probability, and not a prediction interval of probabilities. Packages that I have tried may provide a prediction interval for regression but not for binary classification.


You mention "The Gaussian Processes Web Site", have you checked how many R packages are listed there?


I have been coding in R for more than a decade and contact r-help when I am struggling (I don't see anything wrong with this word) to find a solution in R. Replies like "Google it!" are below my level of my communication and understanding of others.


Best wishes

DK

Well, you only said you were `struggling' to find a package.

Bert may well have done the Google search himself and found numerous resources on such models including links to R (as I did, see below).  If so, his response seems quite natural.

Perhaps, you need to say what is wrong with the hits you got and the packages that they describe to keep a potential response from running in the wrong direction. Perhaps, you have misunderstood the capabilities of a package or failed to grasp an inobvious way to use the package to reach your goal.  In any case, providing some background of why you think the obvious leads do not work in your case can be helpful.

Doing that search myself I see links to R packages, R functions, and to "The Gaussian Processes Web Site" which has a table of possibly relevant softwares.  It seems like there is a lot there to digest.

HTH,

Chuck
