Abstract: Highlights•Developing the close-set and open-set semi-supervised domain generalization (SSDG).•Constructing two web-crawled datasets are for the open-set SSDG.•Establishing strong baselines for SSDG using existing deep learning methods.•Proposing a framework with evolving intermediate domain for SSDG.•The framework outperforms the strong baselines in both close-set and open-set SSDG.
