Dataset Preparation

This project conducts several experiments on the public dataset, Fashion-Gen, which contains 260,480 training text-image pairs for training and 35,528 text-image pairs for inference. The MVLT model can directly process the original image and text without any feature engineering pre-processing of the data. However, it is necessary to sort out the storage form of the data to facilitate the dataloader of torch:

Please download the reorganized dataset from Google Drive (9.72GB).

Preliminaries

Installing the basic libraries python3.6, pytorch1.8, cuda10.1 on UBUNTU18.04. I did validate the flexibility on other versions of libraries and systems, but I think it is easy to adapt with minor changes.

• Create env via conda create -n MVLT python=3.6
• Installing Pytorch via ~/miniconda3/envs/MVLT/bin/python3.6 -m pip install torch==1.8.0+cu111 torchvision==0.9.0+cu111 torchaudio==0.8.0 -f https://download.pytorch.org/whl/torch_stable.html
• Installing the auxiliary libraries via running ~/miniconda3/envs/MVLT/bin/python3.6 -m pip install -r requirements.txt
• The checkpoint of PVT-tiny for pre-training is prepared at ./preweights/pvt_v1/pvt_tiny.pth. You can also try other PVT-v1 and PVT-v2 variants (download link) to further boost the performance if enough GPU memory is available for you.
• Downloading the checkpoint from Google Drive (689.4MB) and move them into ./checkpoints/. Note this tar.gz file contains two weights: checkpoint_retrieval.pth and checkpoint_recognition.pth.

Training

Please note that we only use PVT-Tiny to learn multi-modal features, and other stronger backbone would further improve representation abilities, such as SwinTransformer or PVTv2.

• Please revise your data path (--data-path parameter) in ./scripts_dws/dws_mvlt_exp21.sh or ./scripts_dws/dws_mvlt_ft_exp48.sh
• Just run bash ./scripts_dws/dws_mvlt_exp21.sh for pre-training
• Just run bash ./scripts_dws/dws_mvlt_ft_exp48.sh for fine-tuning

Inference

• Downstream retrieval tasks

  • We provide the zero-shot retrieval performance without any finetuning process, and thus, the well-trained weight could be directly used in the retrieval tasks.
  • Just run bash downstream_retrieval.sh and then get the prediction results of Image-Text Retrieval (ITR) and Text-Image Retrieval (TIR).
    • Text-Image Retrieval (TIR): acc@1: 0.346, acc@5: 0.780, acc@10: 0.895
    • Image-Text Retrieval (ITR): acc@1: 0.331, acc@5: 0.772, acc@10: 0.911

• Downstream recognition tasks

  • This task needs the fine-tuning process because our pre-trained model is not equipped with the classification head.
  • Just run bash downstream_recognition.sh and then get the prediction results of Main-Category Recognition (M-CR) and Sub-Category Recognition (S-CR).
    • Main-category recognition (M-CR): accuracy (0.9825996064928677) macro_f1 (0.8954719842489123)
    • Sub-category recognition (S-CR): accuracy (0.9356554353172651) macro_f1 (0.8285927576055913)
