In this paper, we propose an adaptive Graph-Sign Diffusion (GSD) algorithm to predict the time-varying wind speed in real time, which is crucial for applications like renewable energy generation and weather prediction. The GSD algorithm, formulated on a combination of adaptive graph filtering, graph diffusion, and l(1)-norm optimization, outputs a fast and robust prediction of time-varying graph signals under impulsive noise in an online manner. Experimental results demonstrate the accurate predictions of the GSD algorithm for wind speed at multiple sensor locations.
Online estimation of time-varying wind speed across various locations is a crucial task for applications such as renewable energy generation, weather prediction, and environmental science. In this paper, we propose an adaptive Graph-Sign Diffusion (GSD) algorithm to predict the time-varying wind speed in real time. Leveraging the expressiveness power of Graph Signal Processing, our proposed GSD algorithm is formulated on a combination of adaptive graph filtering, graph diffusion, and l(1)-norm optimization. The GSD algorithm outputs a fast and robust prediction of time-varying graph signals under impulsive noise in an online manner. Experimenting with real-world data shows that the GSD algorithm accurately predicts the time-varying wind speed at multiple sensor locations.
