It claims that it is equivalent to `ctc_greedy_decoder` when `top_paths=1`. This gives the impression that if we only care about the best result, we should always use `ctc_greedy_decoder`. However, `ctc_greedy_decoder` just does a simple argmax at each timestep, which is not equivalent result to a beam_search with `beam_width=100` and `top_paths=1`.\r\n\r\nThe only case they are equivalent is when both `beam_width` and `top_paths` are `1`. This pull request corrects this documentation error."},"comment":{"url":"https://api.github.com/repos/tensorflow/tensorflow/issues/comments/263042241","html_url":"https://github.com/tensorflow/tensorflow/pull/5864#issuecomment-263042241","issue_url":"https://api.github.com/repos/tensorflow/tensorflow/issues/5864","id":263042241,"user":{"login":"ebrevdo","id":1794715,"avatar_url":"https://avatars.githubusercontent.com/u/1794715?v=3","gravatar_id":"","url":"https://api.github.com/users/ebrevdo","html_url":"https://github.com/ebrevdo","followers_url":"https://api.github.com/users/ebrevdo/followers","following_url":"https://api.github.com/users/ebrevdo/following{/other_user}","gists_url":"https://api.github.com/users/ebrevdo/gists{/gist_id}","starred_url":"https://api.github.com/users/ebrevdo/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ebrevdo/subscriptions","organizations_url":"https://api.github.com/users/ebrevdo/orgs","repos_url":"https://api.github.com/users/ebrevdo/repos","events_url":"https://api.github.com/users/ebrevdo/events{/privacy}","received_events_url":"https://api.github.com/users/ebrevdo/received_events","type":"User","site_admin":false},"created_at":"2016-11-26T03:45:39Z","updated_at":"2016-11-26T03:45:39Z","body":"Thanks for catching this!"}}
