We're using a 1 layer Architect.Perceptron on Node 4.2.2. Changing the learning rate / error has given us some minimal speed improvements but definitely not anywhere close to the BrainJS version.\r\n\r\nAny thoughts around this? What else should we try?"},"comment":{"url":"https://api.github.com/repos/cazala/synaptic/issues/comments/223350233","html_url":"https://github.com/cazala/synaptic/issues/70#issuecomment-223350233","issue_url":"https://api.github.com/repos/cazala/synaptic/issues/70","id":223350233,"user":{"login":"UniqueFool","id":16105020,"avatar_url":"https://avatars.githubusercontent.com/u/16105020?v=3","gravatar_id":"","url":"https://api.github.com/users/UniqueFool","html_url":"https://github.com/UniqueFool","followers_url":"https://api.github.com/users/UniqueFool/followers","following_url":"https://api.github.com/users/UniqueFool/following{/other_user}","gists_url":"https://api.github.com/users/UniqueFool/gists{/gist_id}","starred_url":"https://api.github.com/users/UniqueFool/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/UniqueFool/subscriptions","organizations_url":"https://api.github.com/users/UniqueFool/orgs","repos_url":"https://api.github.com/users/UniqueFool/repos","events_url":"https://api.github.com/users/UniqueFool/events{/privacy}","received_events_url":"https://api.github.com/users/UniqueFool/received_events","type":"User","site_admin":false},"created_at":"2016-06-02T16:43:27Z","updated_at":"2016-06-02T16:43:27Z","body":"Just for future reference, here are two github projects which apparently use OpenCL kernels for parallel backpropagation:\r\n\r\n* https://github.com/MacroBull/BPNN_CL\r\n* https://github.com/microo8/clmicronn\r\n"}}
