the mAP on cifar10 is only 0.30 #28
Comments
你好,请问你也只是在cifar-10上得到的结果不太好而在其他数据集上结果正常吗? |
@dweiiiiiiiiii 是的,应该和你结果差不多。 |
@caozhangjie Can you explain why HashNet behaves so badly on CIFAR10? |
Cifar 10 has 10 classes, I recommend replace the class_num to 10. Also, Cifar 10 needs a different backbone network. Please search for a proper backbone. |
Since CIFAR 10 with 10 classes needs class_num to be 10, why COCO dataset with 80 classes is compatible with class_num=1.0? I've tried (64 bits are used.): COCO dataset with class_num=80.0, mAP=0.53 How to explain this? |
For CIFAR-10, I randomly select 100 images per class as the test query set, and 500 images per class as the training set. The remaining images serve as database set.
I trained HashNet with command as follow:
python -u train.py --gpu_id 0 --dataset cifar --prefix resnet50_hashnet --hash_bit 48 --net ResNet50 --lr 0.0003 --class_num 1.0
The final mAP is only 0.302986.
