Contrastive Heliophysical Image Pretraining for Solar Dynamics Observatory Records
Shiyu Shen, Zhe Gao, Taifeng Chai +2
Deep learning has revolutionized solar image analysis, yet most approaches train task-specific encoders from scratch or rely on natural-image pretraining that ignores the unique ch…
Preserving Domain Generalization in Fine-Tuning via Joint Parameter Selection
Bin Pan, Shiyu Shen, Zongbin Wang +2
Domain generalization seeks to develop models trained on a limited set of source domains that are capable of generalizing effectively to unseen target domains. While the predominan…
A Pretrained Probabilistic Transformer for City-Scale Traffic Volume Prediction
Shiyu Shen, Bin Pan, Guirong Xue
City-scale traffic volume prediction plays a pivotal role in intelligent transportation systems, yet remains a challenge due to the inherent incompleteness and bias in observationa…
Hyperspectral Image Generation with Unmixing Guided Diffusion Model
Shiyu Shen, Bin Pan, Ziye Zhang +1
We address hyperspectral image (HSI) synthesis, a problem that has garnered growing interest yet remains constrained by the conditional generative paradigms that limit sample diver…
