Tests passes and rebased on master.\r\nFor illustration of the effectiveness two examples of CIFAR-10 classifier with sigmoid non-linearity with and without batch normalization.\r\n![bn_cifar](https://cloud.githubusercontent.com/assets/4803565/6373172/c37c84ea-bd11-11e4-9f54-1913976c46ae.png)\r\n"},"comment":{"url":"https://api.github.com/repos/BVLC/caffe/issues/comments/94398069","html_url":"https://github.com/BVLC/caffe/pull/1965#issuecomment-94398069","issue_url":"https://api.github.com/repos/BVLC/caffe/issues/1965","id":94398069,"user":{"login":"ducha-aiki","id":4803565,"avatar_url":"https://avatars.githubusercontent.com/u/4803565?v=3","gravatar_id":"","url":"https://api.github.com/users/ducha-aiki","html_url":"https://github.com/ducha-aiki","followers_url":"https://api.github.com/users/ducha-aiki/followers","following_url":"https://api.github.com/users/ducha-aiki/following{/other_user}","gists_url":"https://api.github.com/users/ducha-aiki/gists{/gist_id}","starred_url":"https://api.github.com/users/ducha-aiki/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ducha-aiki/subscriptions","organizations_url":"https://api.github.com/users/ducha-aiki/orgs","repos_url":"https://api.github.com/users/ducha-aiki/repos","events_url":"https://api.github.com/users/ducha-aiki/events{/privacy}","received_events_url":"https://api.github.com/users/ducha-aiki/received_events","type":"User","site_admin":false},"created_at":"2015-04-20T08:58:33Z","updated_at":"2015-04-20T08:58:33Z","body":"@weiliu89, thanks for catch!\r\n\r\nHi Boris, thanks for for observation. It is interesting, that is it very architecture dependent: we have tried on other architectures and there was no difference, as stated in original paper. Still lot of place for exploring :) \r\nThe force_color bug is fixed now, thanks."}}
