Open-Vocabulary Multi-Label Classification via Multi-Modal Knowledge Transfer (AAAI 2023 Oral)

This is the official repository of our paper Open-Vocabulary Multi-Label Classification via Multi-modal Knowledge Transfer.

Setup

pip install -r requirements.txt

Preparation

1. Download pretrained VLP(ViT-B/16) model from OpenAI CLIP.

2. Download images of NUS-WIDE dataset from NUS-WIDE.

3. Download annotations following the BiAM from here.

4. Download other files from here.

The organization of the dataset directory is shown as follows.

Training MKT on NUS-WIDE

python3 train_nus_first_stage.py \
        --data-path path_to_dataset \
        --clip-path path_to_clip_model

The checkpoint of the first training stage is here.

python3 -m torch.distributed.launch --nproc_per_node=8 train_nus_second_stage.py \
        --data-path path_to_dataset \
        --clip-path path_to_clip_model \
        --ckpt-path path_to_first_stage_ckpt

The checkpoint of the second training stage is here.

Testing MKT on NUS-WIDE

python3 train_nus_second_stage.py --eval \
        --data-path path_to_dataset \
        --clip-path path_to_clip_model \
        --ckpt-path path_to_first_stage_ckpt \
        --eval-ckpt path_to_first_second_ckpt \

Inference on A Single Image

python3 inference.py \
        --data-path path_to_dataset \
        --clip-path path_to_clip_model \
        --img-ckpt path_to_first_stage_ckpt \
        --txt-ckpt path_to_second_stage_ckpt \
        --image-path figures/test.jpg
