## 🎉 Highlights

> **<p align="justify"> Abstract:** *Large pre-trained vision language models (VLMs) have shown impressive zero-shot ability on downstream tasks with manually designed prompt. To further adapt VLMs to downstream tasks, soft prompt is proposed to replace manually designed prompt, which undergoes finetuning based on specific domain data. Prior prompt learning methods primarily learn a fixed prompt or residuled prompt from training samples. However, the learned prompts lack diversity and ignore information about unseen domains. In this paper, we reframe the prompt learning framework from a generative perspective and propose a simple yet efficient method for the Domain Generalization (DG) task, namely Soft Prompt Generation (SPG). Specifically, SPG consists of a two-stage training phase and an inference phase. During the training phase, we introduce soft prompt label for each domain, aiming to incorporate the generative model domain knowledge. During the inference phase, the generator of the generative model is employed to obtain instance-specific soft prompts for the unseen target domain. Extensive experiments on five domain generalization benchmarks of three DG tasks demonstrate that SPG achieves state-of-the-art performance.* </p>

<summary>Main Contributions</summary>

1) To the best of our knowledge, we are the first to introduce the generative model into prompt learning in VLMs. Then, we propose a new paradigm of prompt tuning, namely Soft Prompt Generation (SPG).
2) We design a two-stage training phase to align the generative model with domain prompt labels. It incorporates domain knowledge into the generated prompts, enhancing the transferability across unseen domains.
3) Extensive experiments on five datasets for three DG tasks demonstrate that the proposed SPG achieves state-of-the-art performance

## 📁 Data Preparation
**Please download the datasets `PACS`, `VLCS`, `Office-Home`, `TerraIncognita`, and `DomainNet`.**

Follow [DATASETS.md](DATASETS.md) to install the datasets.

## 📈 Training and Evaluation

We provide the running scripts in `scripts`, which allow you to reproduce the results on the paper. 
Make sure you **modify the path in `$DATA`**!

### Training Stage I: Domain Prompt Labels Learning (Optional)

**We provid our dataset split files [spg_coop_splits](https://drive.google.com/drive/folders/1sa7FNaWgs_8Eh4JMO1GZtTUMXqcFRirK?usp=drive_link) and the trained [domain prompt labels](https://drive.google.com/drive/folders/1-2UvAUAhwH4LPHiWPUrtUreRpXU7goY3?usp=drive_link).**

If you wanna use our produced data splits and domain prompt labels, please put split files into the dataset directory (follow [DATASETS.md](DATASETS.md)) and put domain prompt labels in [domain prompt labels](prompt_labels). Then go to the [Training Stage II: Generative Model Pre-training](#training-stage-II-generative-model-pre-training)

<details>
  
<summary>If you wanna use the data splits and domain prompt labels produced by yourself. Please follow the instructions below.</summary>

To obtain data splits and domain prompt labels, please run the bash file in [scripts folder](scripts/spg_coop) as follows.

```bash
# Example: trains on PACS dataset with ResNet50 as the backbone, and the gpu id is 0. 
bash scripts/spg_coop/spg_coop.sh pacs RN50 0
```

</details>

### Training Stage II: Generative Model Pre-training
Please refer to [DATASETS.md](DATASETS.md), and make sure that our produced [data splits](datasets) are in your data path. The bash files of three types of DG tasks in [scripts folder](scripts/spg_cgan).

For multi-source Domain Generalization
```bash
# Example: trains on PACS dataset with ResNet50 as the backbone, and the gpu id is 0. 
bash scripts/spg_cgan/spg_cgan.sh pacs spg RN50 0
```

For Single-source Domain Generation
```bash
# Example: trains on VLCS dataset with ResNet50 as the backbone, and the gpu id is 1. 
bash scripts/spg_cgan/single.sh vlcs spg RN50 1
```

For Cross-dataset Domain Generation
```bash
# Example: trains on DomainNet dataset with ViT-B/16 as the backbone, and the gpu id is 2. 
bash scripts/spg_cgan/cross.sh spg ViT-B/16 2
```

### Evaluation
For multi-source Domain Generalization

```bash
# Example: test PACS dataset with ResNet50 as the backbone, and the gpu id is 0. 
bash scripts/test_all.sh pacs spg RN50 0
```
