VLLaVO: Mitigating Visual Gap through LLMs

1 code implementation6 Jan 2024 Shuhao Chen, Yulong Zhang, Weisen Jiang, Jiangang Lu, Yu Zhang

Recent advances achieved by deep learning models rely on the independent and identically distributed assumption, hindering their applications in real-world scenarios with domain shifts.

Domain-Guided Conditional Diffusion Model for Unsupervised Domain Adaptation

no code implementations23 Sep 2023 Yulong Zhang, Shuhao Chen, Weisen Jiang, Yu Zhang, Jiangang Lu, James T. Kwok

However, the performance of existing UDA methods is constrained by the large domain shift and limited target domain data.

Diffusion-based Target Sampler for Unsupervised Domain Adaptation

no code implementations17 Mar 2023 Yulong Zhang, Shuhao Chen, Yu Zhang, Jiangang Lu

The generated samples can well simulate the data distribution of the target domain and help existing UDA methods transfer from the source domain to the target domain more easily, thus improving the transfer performance.
