I’d like to ask, is there a way to evaluate multiple input values (images) or batches at once? It would significantly improve our performance.\r\n\r\nSomething like:\r\n`var dictionary = new Dictionary<string, List<float>> { { \"features1\", imageTensor1 }, { \"features2\", imageTensor2 } };\r\nvar output = evaluateModelManagedF.Evaluate(dictionary, “OutputNodes.z”); //where output is f.e. Dictionary<string, List<float>>`\r\n\r\nThanks for your response.\r\n\r\nI wish you all the good luck with CNTK.\r\n\r\nRegards,\r\nMiro\r\n"},"comment":{"url":"https://api.github.com/repos/Microsoft/CNTK/issues/comments/226412653","html_url":"https://github.com/Microsoft/CNTK/issues/589#issuecomment-226412653","issue_url":"https://api.github.com/repos/Microsoft/CNTK/issues/589","id":226412653,"user":{"login":"gaizkan","id":10653002,"avatar_url":"https://avatars.githubusercontent.com/u/10653002?v=3","gravatar_id":"","url":"https://api.github.com/users/gaizkan","html_url":"https://github.com/gaizkan","followers_url":"https://api.github.com/users/gaizkan/followers","following_url":"https://api.github.com/users/gaizkan/following{/other_user}","gists_url":"https://api.github.com/users/gaizkan/gists{/gist_id}","starred_url":"https://api.github.com/users/gaizkan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/gaizkan/subscriptions","organizations_url":"https://api.github.com/users/gaizkan/orgs","repos_url":"https://api.github.com/users/gaizkan/repos","events_url":"https://api.github.com/users/gaizkan/events{/privacy}","received_events_url":"https://api.github.com/users/gaizkan/received_events","type":"User","site_admin":false},"created_at":"2016-06-16T07:48:53Z","updated_at":"2016-06-16T07:48:53Z","body":"Correction:\r\nThe evaluation library doesn't do batches. In my example it takes an input of [1 x *] and computes the product with a constant (which results in a [1 x *] vector). This is different than processing [1 x 1] with a constant 3 times. I haven't tested it with images, but I don't think this will work. \r\n\r\nWe've added this request for the next version of the evaluation dll.\r\nThanks,\r\nGaizka\r\n"}}
