There's been a decent literature based on this work (over 60 citations in 2 years) including some work I'm starting on and it'd be helpful to not have to hand roll GP optimization every time I use this kernel.\r\n\r\nI looked around the list of currently implemented kernels and couldn't find it but if I just missed it let me know.\r\n\r\nI guess the broader question here is how close you want this package to follow the literature. `sklearn`, for example, has a policy of _not_ closely following the literature, so that's not necessarily a bad thing, but it'd be helpful to have a guideline on what the package's goals are in this domain.\r\n\r\nLet me know what you guys think. Thanks 😀 !\r\n\r\n(I'd be willing to help out in adding this though I'm not as of yet familiar with the internals of the package)"},"comment":{"url":"https://api.github.com/repos/SheffieldML/GPy/issues/comments/250907985","html_url":"https://github.com/SheffieldML/GPy/issues/401#issuecomment-250907985","issue_url":"https://api.github.com/repos/SheffieldML/GPy/issues/401","id":250907985,"user":{"login":"NoahSlv","id":17998648,"avatar_url":"https://avatars.githubusercontent.com/u/17998648?v=3","gravatar_id":"","url":"https://api.github.com/users/NoahSlv","html_url":"https://github.com/NoahSlv","followers_url":"https://api.github.com/users/NoahSlv/followers","following_url":"https://api.github.com/users/NoahSlv/following{/other_user}","gists_url":"https://api.github.com/users/NoahSlv/gists{/gist_id}","starred_url":"https://api.github.com/users/NoahSlv/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/NoahSlv/subscriptions","organizations_url":"https://api.github.com/users/NoahSlv/orgs","repos_url":"https://api.github.com/users/NoahSlv/repos","events_url":"https://api.github.com/users/NoahSlv/events{/privacy}","received_events_url":"https://api.github.com/users/NoahSlv/received_events","type":"User","site_admin":false},"created_at":"2016-10-01T11:42:38Z","updated_at":"2016-10-01T11:42:38Z","body":"Hi,\r\n\r\nJust checking in to see if any new code is available for this.  @cdipaolo any chance you can push the latest?"}}
