github:

TYLfromSEU/DPStyler: DPStyler: Dynamic PromptStyler for Source-Free Domain Generalization

论文:

这篇论文还是在PromptStyler:Prompt-driven Style Generation for Source-free Domain Generalization基础上对一些架构进行修改的。

Contribution

Style Generation Module:

dynamically refresh style by regenerating all style word vectors including Random and StyleMix between epochs.(randomly select one method)

Style Removal Module:

propose a domain uncertainty loss after encoder, to reduce specific style information and learn domain-invariant features

Model Ensemble:inference stage

for each text template, train a model and each model is involved in the inference process

Because introducing more randomness into the training process

原因：直接使用作者github上面的environment.yml文件发生报错。里面的配置有的用python3.7，有的用3.8很混乱。搞不懂作者是怎么配置的。

但是使用我之前配置的虚拟环境也可以这场运行这篇论文的代码。

链接：zhanghr2001/PromptTA: Source-free Domain Generalization

这是我之前复现这篇论文的环境，根据readme，配置到requirement.txt就可以。

2、连接超时Connection timed out'

requests.exceptions.ConnectionError: HTTPSConnectionPool(host='drive.google.com', port=443): Max retries exceeded with url: /uc?id=1gkbf_KaxoBws-GWT3XIPZ7BnkqbAxIFa (Caused by NewConnectionError('<urllib3.connection.HTTPSConnection object at 0x7f20626e8990>: Failed to establish a new connection: [Errno 110] Connection timed out'))

原因：要在作者给的github上的链接上面下载数据集，我用的之前的数据集，有一些问题。
