Single-class image classification of Distilling Knowledge by Mimicking Features.

LSHFM.classification

This is the PyTorch source code for Distilling Knowledge by Mimicking Features. We provide all codes for three tasks.

• single-label image classification: LSHFM.singleclassification
• multi-label image classification: LSHFM.multiclassification
• object detection: LSHFM.detection

Dependence

• python3
• pytorch 1.7.1
• torchvision 0.8.2

Prepare the dataset

Please prepare the COCO and VOC datasets by youself. Then you need to check and edit the get_data_path function in src/dataset/coco_utils.py and src/dataset/voc_utils.py.

CIFAR-100

Teacher:

• wrn_40_2
• resnet56
• resnet110
• resnet32x4
• vgg13
• ResNet50

Student:

• wrn_16_2
• wrn_40_1
• resnet20
• resnet32
• resnet8x4
• vgg8
• MobileNetV2
• ShffleNetV1
• ShffleNetV2

Train vanilla teacher and student

Train the teacher:

python train_vanilla.py --model [teacher network] --gpus 0
e.g.
python train_vanilla.py --model resnet56 --gpus 0

Train the student:

python train_vanilla.py --model [student network] --gpus 0
e.g.
python train_vanilla.py --model wrn_16_2 --gpus 0

Feature mimicking & knowledge distillation

Please use the below command to run experiments:

python train_student.py --model_s [student network] --path_t [path to the teacher] --gpus 0
e.g.
python train_student.py --model_s wrn_16_2 --path_t save/models/wrn_40_2_vanilla/ckpt_epoch_240.pth --gpus 0

Imagenet

Please use the below command to run experiments:

python imagenet_lsh.py /mnt/ramdisk/ImageNet --gpus 0,1 -a ResNet18 --teacher-arch ResNet34
