Deep-Learning-Based Precipitation Nowcasting with Ground Weather Station Data and Radar Data

1 code implementation20 Oct 2022 Jihoon Ko, Kyuhan Lee, Hyunjin Hwang, Kijung Shin

Recently, many deep-learning techniques have been applied to various weather-related prediction tasks, including precipitation nowcasting (i. e., predicting precipitation levels and locations in the near future).

AHP: Learning to Negative Sample for Hyperedge Prediction

1 code implementation13 Apr 2022 Hyunjin Hwang, Seungwoo Lee, Chanyoung Park, Kijung Shin

Since it is prohibitive to use all of them as negative examples for model training, it is inevitable to sample a very small portion of them, and to this end, heuristic sampling schemes have been employed.

Effective Training Strategies for Deep-learning-based Precipitation Nowcasting and Estimation

no code implementations17 Feb 2022 Jihoon Ko, Kyuhan Lee, Hyunjin Hwang, Seok-Geun Oh, Seok-Woo Son, Kijung Shin

It is highlighted that our pre-training scheme and new loss function improve the critical success index (CSI) of nowcasting of heavy rainfall (at least 10 mm/hr) by up to 95. 7% and 43. 6%, respectively, at a 5-hr lead time.
