The difference is that the network is not replicated into a linear sequence of operations, but into a tree structure.\r\n\r\nMaybe a tree traversal can already be implemented using `While` ops, but I'm not sure how.\r\n(A bottom-up traversal of a tree would have to be performed for each entry in the dataset, applying the network at each node)\r\nInstinctively, I have the impression that this would need a new C++ op that generalizes `While`.\r\n"},"comment":{"url":"https://api.github.com/repos/tensorflow/tensorflow/issues/comments/225710234","html_url":"https://github.com/tensorflow/tensorflow/issues/2237#issuecomment-225710234","issue_url":"https://api.github.com/repos/tensorflow/tensorflow/issues/2237","id":225710234,"user":{"login":"marcellomh","id":19917084,"avatar_url":"https://avatars.githubusercontent.com/u/19917084?v=3","gravatar_id":"","url":"https://api.github.com/users/marcellomh","html_url":"https://github.com/marcellomh","followers_url":"https://api.github.com/users/marcellomh/followers","following_url":"https://api.github.com/users/marcellomh/following{/other_user}","gists_url":"https://api.github.com/users/marcellomh/gists{/gist_id}","starred_url":"https://api.github.com/users/marcellomh/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/marcellomh/subscriptions","organizations_url":"https://api.github.com/users/marcellomh/orgs","repos_url":"https://api.github.com/users/marcellomh/repos","events_url":"https://api.github.com/users/marcellomh/events{/privacy}","received_events_url":"https://api.github.com/users/marcellomh/received_events","type":"User","site_admin":false},"created_at":"2016-06-13T21:12:43Z","updated_at":"2016-06-13T21:12:43Z","body":"Hi Folks,\r\n\r\nI'm a Google employee.
