This addresses feature request https://github.com/allenai/allennlp/issues/537 . Refer the following [blog post](https://medium.com/@surmenok/estimating-optimal-learning-rate-for-a-deep-neural-network-ce32f2556ce0) linked in that issue for overview of how the finder works.\r\n\r\nThe major changes are making few of the fields in `Trainer` \"public\" (ie remove underscore from names). I have used matplotlib to plot learning rate vs loss graph.\r\n\r\nI haven't written unit tests, if the current code is ok, will do. I am a little unsure on what to test exactly."},"comment":{"url":"https://api.github.com/repos/allenai/allennlp/issues/comments/430082170","html_url":"https://github.com/allenai/allennlp/pull/1776#issuecomment-430082170","issue_url":"https://api.github.com/repos/allenai/allennlp/issues/1776","id":430082170,"node_id":"MDEyOklzc3VlQ29tbWVudDQzMDA4MjE3MA==","user":{"login":"sai-prasanna","id":3595526,"node_id":"MDQ6VXNlcjM1OTU1MjY=","avatar_url":"https://avatars1.githubusercontent.com/u/3595526?v=4","gravatar_id":"","url":"https://api.github.com/users/sai-prasanna","html_url":"https://github.com/sai-prasanna","followers_url":"https://api.github.com/users/sai-prasanna/followers","following_url":"https://api.github.com/users/sai-prasanna/following{/other_user}","gists_url":"https://api.github.com/users/sai-prasanna/gists{/gist_id}","starred_url":"https://api.github.com/users/sai-prasanna/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/sai-prasanna/subscriptions","organizations_url":"https://api.github.com/users/sai-prasanna/orgs","repos_url":"https://api.github.com/users/sai-prasanna/repos","events_url":"https://api.github.com/users/sai-prasanna/events{/privacy}","received_events_url":"https://api.github.com/users/sai-prasanna/received_events","type":"User","site_admin":false},"created_at":"2018-10-16T02:49:01Z","updated_at":"2018-10-16T02:49:01Z","author_association":"NONE","body":"Would a test with a simple model and asserting whether the graph gets created do?\r\n\r\nLittle unsure on how to test the effects of command parameters like stopping factor etc."}}
