VL-Adapter

Authors: Yi-Lin Sung, Jaemin Cho, Mohit Bansal
Paper: "VL-Adapter: Parameter-Efficient Transfer Learning for Vision-and-Language Tasks" (CVPR 2022)

We evaluate VL-adapter in a unified multi-task setup on both image-text and video-text benchmarks. For the image-text tasks, we use four diverse V&L datasets: VQAv2, GQA, NLVR2, and MSCOCO image captioning. For video-text tasks, we use TVQA, How2QA, TVC, and YC2C.

Our results demonstrate that training the adapter with the weight-sharing technique (4.18% of total parameters for image-text tasks and 3.39% for video-text tasks) can match the performance of fine-tuning the entire model.

** Note ** Please go into CLIP-ViL folder and follow the README there for running the experiments of adapters on CLIP-ViL. This README is for adapters on VL-Bart.

Installation

# Create python environment (optional)
conda create -n vlt5 python=3.8
source activate vlt5

# Install python dependencies
pip install -r requirements.txt

# Download T5/BART backbone checkpoint
python download_backbones.py

# For MSCOCO captioning evaluation (optional; for captioning only)
python -c "import language_evaluation; language_evaluation.download('coco')"

Data

Image-text dataset

Please go to link to download the processed CLIP features. We suggest to use gdrive to download it. Unzip the downloaded file and arrange the folders following the format which is shown in the "Code Structure."

If you would like to use dgrive to download the data, please try the following command

gdrive download 1O_RU1iFh_sbItZCTkOHUrbVIQQ_89Djj

Extract your own CLIP features

Please refer to feature_extraction for more details.

Video-text dataset

Please go to VALUE to download the ViT processed data.
