Adversarial Knowledge Transfer from Unlabeled Data

This repository is the official implementation our paper titled "Adversarial Knowledge Transfer from Unlabeled Data" accepted to ACM-MM 2020. Please refer project page for more details.

Implementation Details

Our implementation is in PyTorch [1] with python 3.6.7. We train all our model on GeForce RTX 2080 Ti GPUs. This implementation currently uses one gpu and can be modified to use multiple gpus for larger batch size.

Python Packages

Please refer to the requirements.txt file for all the packages we used to create the environment for training our models. We create an environment in anaconda.

Datasets

This is a working code of our proposed method for PASCAL-VOC/ImageNet experiment. We use PASCAL-VOC[2] dataset as the labeled target dataset and ImageNet[3] as unlabeled source dataset.

Usage

To train a model on PASCAL-VOC and ImageNet experiment WITH GPU

python train.py --pascal_path <path-to-pascal-voc-dataset> \
                --imgnet_path <path-to-imagenet-dataset>   \
                --gpu <gpu-id-to-use>

python train.py --pascal_path /datasets/pascal-voc-2007/   \
                --imgnet_path /datasets/imagenet-dataset/  \
                --gpu 0

To test your trained model WITH GPU

python train.py --pascal_path <path-to-pascal-voc-dataset> \
                --model <path-to-trained-model>            \
                --gpu <gpu-id-to-use>                      \
                --test 1

python train.py --pascal_path /datasets/pascal-voc-2007/   \
                --model ./checkpoints/best-model.pth       \
                --gpu 0                                    \
                --test 1
