Prompting Language-Informed Distribution (PLID)

[ECCV 2024] Prompting Language-Informed Distribution for Compositional Zero-Shot Learning

This repo contains the source code of the above ECCV2024 paper for compositional zero-shot learning (CZSL) tasks. The CZSL task aims to learn from a subset of seen state-object compositions, and recognize both seen and unseen compositions, either in a closed world where the compositional classes are assumed to be feasible, or in an open world where infeasible compositional classes are taken into account in recognition. The figure CZSL Task illustrates the CZSL task. Our method PLID, based on CLIP model, leverages large-language models (LLM) and Gaussian distributions to formulate informative and diverse prompts for text input.

Setup

conda create --name clip python=3.7
conda activate clip
pip3 install torch torchvision torchaudio --extra-index-url https://download.pytorch.org/whl/cu113
pip3 install ftfy regex tqdm scipy pandas
pip3 install git+https://github.com/openai/CLIP.git

Alternatively, you can use pip install -r requirements.txt to install all the dependencies.

Download Dataset

Download raw data

We experiment with three datasets: MIT-States, UT-Zappos, and C-GQA.

sh download_data.sh

If you already have setup the datasets, you can use symlink and ensure the following paths exist: data/<dataset> where <datasets> = {'mit-states', 'ut-zappos', 'cgqa'}.

Training

cd exp/mit-states
bash train_model.sh 0

You can replace mit-states with ut-zappos or cgqa for training our model on other datasets.

Evaluation

We evaluate our models in two settings: closed-world and open-world.

cd exp/mit-states
bash eval_model.sh 0 closed

You can change the closed to open switch evaluation from closed-world to open-world.

Credits

The project uses openly available model, code, and datasets. Please see the credits.
