Our-RRM-ResNet about rrm HOT 3 CLOSED

Firstly you need to use RRM (one-step) to generate pseudo labels of all training data, then you can use them to train any fully segmentation model (FCN), such as deeplab, PSPnet and so on. when I train the FCN, i.e., deeplab-v1 and v2, I use the official code and all the settings are the same with their papers. If you do not want the pre-trained model on COCO, I suggest you to train another FCN such as deeplab v3 or v3+. If you find the init model without COCO pre-trained using official code, please let me know, because I also think it is not a good choice.

@zbf1991 Thank you for your explanation. I have gotten a good result from official deeplabv2 with VGG16 and deeplabv3 is helpful. But, I cannot get a good result from official deeplabv2 with resnet101 without loading pretrain weight on MS COCO. Here is where I stuck. Do you train deeplabv2-resnet101 without any pretrained weights such as ImageNet?

Without COCO pretrain weight, I do not think people can get a good result on deeplabv2-resnet101 with the same setting in deeplabv2 paper. For example, in deeplabv2-resnet101, they freeze the batch normalization in each layer so people must load pretrain weight if they use the same setting of deeplabv2. In addition, they set different learning rates to different layers, so people may get a poor result if they train deeplabv2-resnet101 without any pretrain weight. Or, maybe I am wrong.

Another question, which official code of deeplabv2-resnet101 do you use? I think there are two official codes. One is Caffe model and another is Tensorflow(deeplabv3). Do you use its init.caffemodel? I try to delete it before training. However, the performance of deeplabv2-resnet101 became very worse.

I used caffe-version and use its init.caffemodel
