Large performance gap between trained model using default setting and the provided trained model. #13
Comments
Did anyone encounter the same situation or have ideas about the situation? |
which dataset (among train/train_aug/val) do you use? is it train? and npy or png? I think the performance of your custom trained version is similar to that of my execution (pretrained / custom both) The performance of your pretrained implementation is too high. |
@halbielee Hi, I use the default training setting of this repo, that is, using voc12/train_aug.txt to train the model and evaluating on VOC2012/ImageSets/Segmentation/train.txt. |
@bityangke Can you share the exact pretrained weight file [resnet38_SEAM.pth]? |
@halbielee Hi I use the pre-trained model on Google Drive |
@bityangke 0/60 background score: 0.000 mIoU: 23.150% I got the same result and the number 55.406 % is the number on the paper Table 1. |
@halbielee My bad. I need the CAM generated by PSA for a downstream task, so I put the PSA CAM in VOC2012/SegmentationClass/ to replace the original GT images. I evaluated the custom model on another machine with original GT data, so the result was not affected; when I changed to the correct GT, the result of pretrained model was exactly the same as your result. |
Is pretrained model that you used referring to 'ilsvrc-cls_rna-a1_cls1000_ep-0001.params' or 'resnet38_SEAM.pth'? |
With the provided trained 'resnet38_SEAM.pth', the results of SEAM step evaluation:
When using the 'resnet38_SEAM.pth' trained myself using the default settings (except that I used two GPU cards,the batch size was still set to 8), the results of SEAM step evaluation:
