[Training][COCO] Reproduce original performance

[knorth55]

Currently, this repo's performance of both voc and coco is lower than original ones.

Thanks for the repo. What are the current results?

Edit: Never mind I see it is included in examples.

@patrickpoirson Hi, thank you for getting interested in. Currently, I do not have enough time to improve this repo, but I'm trying to reproduce the original repo's performance. I survey training results, and what is the most different from original is rpn_loc_loss and rpn_cls_loss, so I'm now debugging it.

Edit: Never mind I see it is included in examples.

The results shown in example is the result of model converted from mxnet, so it is not pure chainer training result.

I update README.md https://github.com/knorth55/chainer-fcis/blob/master/examples/voc/README.md

there is quite big different from original repo ;(

I debugged and finally reproduce VOC training accuracy as original repo!
