Depth-Based Local Recentering of Maxmin Landmarks for Lazy Witness Persistence
Yifan Zhang
We study a local post-processing rule for maxmin (farthest-point) landmark selection in lazy witness persistence. Maxmin landmarks induce nearest-landmark cells. Within each cell,…
FusionCast: Enhancing Precipitation Nowcasting with Asymmetric Cross-Modal Fusion and Future Radar Priors
Henan Wang, Shengwu Xiong, Yifang Zhang +4
Deep learning has significantly improved the accuracy of precipitation nowcasting. However, most existing multimodal models typically use simple channel concatenation or interpolat…
A Progressive Framework of Vision-language Knowledge Distillation and Alignment for Multilingual Scene
Wenbo Zhang, Yifan Zhang, Jianfeng Lin +3
Pre-trained vision-language (V-L) models such as CLIP have shown excellent performance in many downstream cross-modal tasks. However, most of them are only applicable to the Englis…
GeoGPT: Understanding and Processing Geospatial Tasks through An Autonomous GPT
Yifan Zhang, Cheng Wei, Shangyou Wu +2
Decision-makers in GIS need to combine a series of spatial algorithms and operations to solve geospatial tasks. For example, in the task of facility siting, the Buffer tool is usua…
