But for a problem I am working on now, I see the top interactions are f10|f10 and f10|f10|f10 and f10|f10|f10|f10... what does that mean? Should I create a new feature called f10 * f10 or should I create an identical f10 as a new feature so that it could be split at more than 1 node?\r\n\r\nAppreciate your clarification!\r\n\r\nLi"},"comment":{"url":"https://api.github.com/repos/Far0n/xgbfi/issues/comments/183843377","html_url":"https://github.com/Far0n/xgbfi/issues/2#issuecomment-183843377","issue_url":"https://api.github.com/repos/Far0n/xgbfi/issues/2","id":183843377,"user":{"login":"Far0n","id":6949295,"avatar_url":"https://avatars.githubusercontent.com/u/6949295?v=3","gravatar_id":"","url":"https://api.github.com/users/Far0n","html_url":"https://github.com/Far0n","followers_url":"https://api.github.com/users/Far0n/followers","following_url":"https://api.github.com/users/Far0n/following{/other_user}","gists_url":"https://api.github.com/users/Far0n/gists{/gist_id}","starred_url":"https://api.github.com/users/Far0n/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/Far0n/subscriptions","organizations_url":"https://api.github.com/users/Far0n/orgs","repos_url":"https://api.github.com/users/Far0n/repos","events_url":"https://api.github.com/users/Far0n/events{/privacy}","received_events_url":"https://api.github.com/users/Far0n/received_events","type":"User","site_admin":false},"created_at":"2016-02-14T07:31:30Z","updated_at":"2016-02-14T07:31:30Z","body":"Thx Walt, that covers the most. :) Additionally: adding an identical *f10* would just bring in redundancy, which is not helpful."}}
