What you'd really want to do is run epsilon from say 1e-2 to 1e-8, and print the results, and what you want to see is the finite difference derivative first getting closer to the analytic derivative as epsilon decreases, and then become worse again as you get into floating point rounding errors..."},"comment":{"url":"https://api.github.com/repos/trthatcher/MLKernels.jl/issues/comments/96675110","html_url":"https://github.com/trthatcher/MLKernels.jl/pull/4#issuecomment-96675110","issue_url":"https://api.github.com/repos/trthatcher/MLKernels.jl/issues/4","id":96675110,"user":{"login":"coveralls","id":2354108,"avatar_url":"https://avatars.githubusercontent.com/u/2354108?v=3","gravatar_id":"","url":"https://api.github.com/users/coveralls","html_url":"https://github.com/coveralls","followers_url":"https://api.github.com/users/coveralls/followers","following_url":"https://api.github.com/users/coveralls/following{/other_user}","gists_url":"https://api.github.com/users/coveralls/gists{/gist_id}","starred_url":"https://api.github.com/users/coveralls/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/coveralls/subscriptions","organizations_url":"https://api.github.com/users/coveralls/orgs","repos_url":"https://api.github.com/users/coveralls/repos","events_url":"https://api.github.com/users/coveralls/events{/privacy}","received_events_url":"https://api.github.com/users/coveralls/received_events","type":"User","site_admin":false},"created_at":"2015-04-27T14:27:38Z","updated_at":"2015-04-27T14:27:38Z","body":"\n[![Coverage Status](https://coveralls.io/builds/2431355/badge)](https://coveralls.io/builds/2431355)\n\nCoverage increased (+2.36%) to 84.34% when pulling **7ab13cd3831825140fe662927ae3885a5973c21b on st--:master** into **c30c528473cad39731107288547c8bdde76cf737 on trthatcher:development**.\n"}}
