Your parameter is 32*1(iter_size)*4(GPU), i have to set it to 16(bath_size)*4(iter_size)*2(GPU) make batchsize to be 128 due to my poor server,what about other parameter?such as the stepvalue and max_iter, keep it still or multiple 4 because the iter_size become 4 rather than 1? Do i need to change other parameter？ i do the work on the ucf101 spilt1.\r\n\r\ni also have another question, you set the new_length to 5 in the tsn_bn_inception_flow_train_val.prototxt,\r\nbut the better parameter should be 10 according to the 2 stream paper(NIPS14).Is it a bug or 5 is better for TSN?\r\nThanks!"},"comment":{"url":"https://api.github.com/repos/yjxiong/temporal-segment-networks/issues/comments/258357120","html_url":"https://github.com/yjxiong/temporal-segment-networks/issues/29#issuecomment-258357120","issue_url":"https://api.github.com/repos/yjxiong/temporal-segment-networks/issues/29","id":258357120,"user":{"login":"yjxiong","id":6830199,"avatar_url":"https://avatars.githubusercontent.com/u/6830199?v=3","gravatar_id":"","url":"https://api.github.com/users/yjxiong","html_url":"https://github.com/yjxiong","followers_url":"https://api.github.com/users/yjxiong/followers","following_url":"https://api.github.com/users/yjxiong/following{/other_user}","gists_url":"https://api.github.com/users/yjxiong/gists{/gist_id}","starred_url":"https://api.github.com/users/yjxiong/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/yjxiong/subscriptions","organizations_url":"https://api.github.com/users/yjxiong/orgs","repos_url":"https://api.github.com/users/yjxiong/repos","events_url":"https://api.github.com/users/yjxiong/events{/privacy}","received_events_url":"https://api.github.com/users/yjxiong/received_events","type":"User","site_admin":false},"created_at":"2016-11-04T06:53:30Z","updated_at":"2016-11-04T06:53:30Z","body":"Generally, as long as you use the same effective batchsize, no other parameter need to be altered.\r\n\r\nFor the `new_length`, 5 is working reasonably well with TSN and leads to faster training. So we use 5 instead of 10. It is not a bug."}}
