For continuous data, we emulate a continuous probability distribution which supports finding cumulative sum upto a particular value, and finding value upto a specific cumulative probability [Quantiles]. \r\nFor categorical fields, we emulate a probability mass function which supports finding the probability associated with every class.\r\nThe continuous histogram follows this paper: http://www.jmlr.org/papers/volume11/ben-haim10a/ben-haim10a.pdf\r\n\r\nNote: This is a sub-task of https://issues.apache.org/jira/browse/FLINK-1727 which already has a PR pending review at https://github.com/apache/flink/pull/710."},"comment":{"url":"https://api.github.com/repos/apache/flink/issues/comments/114946436","html_url":"https://github.com/apache/flink/pull/861#issuecomment-114946436","issue_url":"https://api.github.com/repos/apache/flink/issues/861","id":114946436,"user":{"login":"thvasilo","id":9048995,"avatar_url":"https://avatars.githubusercontent.com/u/9048995?v=3","gravatar_id":"","url":"https://api.github.com/users/thvasilo","html_url":"https://github.com/thvasilo","followers_url":"https://api.github.com/users/thvasilo/followers","following_url":"https://api.github.com/users/thvasilo/following{/other_user}","gists_url":"https://api.github.com/users/thvasilo/gists{/gist_id}","starred_url":"https://api.github.com/users/thvasilo/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/thvasilo/subscriptions","organizations_url":"https://api.github.com/users/thvasilo/orgs","repos_url":"https://api.github.com/users/thvasilo/repos","events_url":"https://api.github.com/users/thvasilo/events{/privacy}","received_events_url":"https://api.github.com/users/thvasilo/received_events","type":"User","site_admin":false},"created_at":"2015-06-24T17:21:06Z","updated_at":"2015-06-24T17:21:06Z","body":"Yes, we should avoid mixing java and Scala of possible.\n\n-- \nSent from a mobile device.
