WxFM-XL: Adapting Univariate Foundation Models to Multi-Station Weather Forecasting
Xiao Wang, Changjian Chen, Zhuo Tang +3
With the rise of univariate time series foundation models (e.g., Sundial, Timer), initial efforts have been made to extend them to multivariate settings. However, these models main…
StationPDE: Station-Oriented Surface PDE Learning for Multi-Station Multivariate Weather Forecasting
Xiao Wang, Changjian Chen, Rongwen Li +3
Multi-station multivariate weather forecasting aims to forecast future weather variables at multiple weather stations from historical surface observations. Existing station forecas…
Learning-State-Aware Dynamic Generative Data Augmentation on Small-Scale Datasets
Ting Xiang, Chenxi Deng, Jinhui Zhao +4
Small-scale image classification is often limited by the scarcity of training data. Generative data augmentation (GDA) based on pretrained generative models has emerged as an effec…
Human-Guided Causal Knowledge Injection for Virtual Cells
Pengcheng Wang, Changjian Chen, Zhuo Tang +4
Virtual cells employ machine learning models to simulate and predict cellular behaviors, serving as a critical computational framework for investigating health and disease. Injecti…
CausalTAD: Injecting Causal Knowledge into Large Language Models for Tabular Anomaly Detection
Ruiqi Wang, Ruikang Liu, Runyu Chen +4
