HighAir: A Hierarchical Graph Neural Network-Based Air Quality Forecasting Method

1 code implementation12 Jan 2021 Jiahui Xu, Ling Chen, Mingqi Lv, Chaoqun Zhan, Sanjian Chen, Jian Chang

Existing air quality forecasting methods cannot effectively model the diffusion processes of air pollutants between cities and monitoring stations, which may suddenly deteriorate the air quality of a region.

Symmetric Dilated Convolution for Surgical Gesture Recognition

1 code implementation13 Jul 2020 Jinglu Zhang, Yinyu Nie, Yao Lyu, Hailin Li, Jian Chang, Xiaosong Yang, Jian Jun Zhang

The experiment results demonstrate the ability of our method on capturing long-term frame dependencies, which largely outperform the state-of-the-art methods on the frame-wise accuracy up to ~6 points and the F1@50 score ~6 points.
