Universal Vision-Language Dense Retrieval (UniVL-DR)

There are source codes for Universal Vision-Language Dense Retrieval Our Paper.

Requirement

  • Python==3.7
  • Pytorch
  • transformers
  • clip
  • faiss-cpu==1.7.0
  • tqdm
  • numpy
  • base64
  • Install the pytrec_eval from https://github.com/cvangysel/pytrec_eval

Data and Checkpoint

  • All these files can be downloaded and you should put them in the corresponding folders.
  • All data can be found at Ali Drive. Please note that the imgs.tsv file should be downloaded from the project of WebQA (by downloading the data from this link and running 7z x imgs.7z.001).
  • The checkpoint_multi_inb (The checkpoint of CLIP-DPR) can be found at Ali Drive.
  • The checkpoint_multi_hn (The checkpoint of UniVL-DR) can be found at Ali Drive.

Train UniVL-DR

  • UniVL-DR inherits CLIP (ViT-B/32). The texts must be truncated by 77 tokens and you can try different vision-language models. As shown in our experiments, we suggest to use the dual encoder models.
  • There are two steps to train UniVL-DRR:
  • First step: Go to the CLIP-DPR folder and train models using inbatch negatives:
bash train_multi.sh
  • Second step: Then using CLIP-DPR to generate hard negatives for training UniVL-DR:
bash get_hn.sh
  • Final step: Go to the UniVL-DR folder and train models using hard negatives:
bash train_multi.sh

Evaluate Retrieval Effectiveness

  • These experimental results are shown in Table 1 of our paper.
  • Go to the CLIP-DPR or UniVL-DR folder and evaluate model performance as follow:
bash gen_embeds.sh

bash retrieval.sh

Results

The results are shown as follows.
