Explainable Predictive Model for Suicidal Ideation During COVID-19: Social Media Discourse Study
Published 2025-01-01“…ConclusionsConsidering the dynamic nature of suicidal behavior posts, we proposed a fused architecture that captures both localized and generalized contextual information that is important for understanding the language patterns and predict the evolution of suicidal ideation over time. According to Local Interpretable Model-Agnostic Explanations (LIME) and Shapley Additive Explanations (SHAP) XAI algorithms, there was a drift in the features during and before COVID-19. …”

Accuracy Evaluation of Multi-Source Precipitation Data in Mountain Flood Simulation in Guoning Village, Xiahe County
Published 2025-02-01“…From 22:00 on September 6, 2023 to 04:00 (Beijing Time) on September 7, Xiahe County in Gansu Province experienced severe convective weather, with short-term heavy rainfall in some areas, causing flash floods in Guoning Village, Xiahe County, resulting in casualties.In this study, the characteristics of Radar Quantitative Precipitation Estimation (Radar-QPE), FengYun 4B Quantitative Precipitation Estimation (FY4B-QPE), and CMA Multi-source Precipitation Analysis (CMPA) precipitation products were contrastive analyzed based on meteorological station observations.These precipitation data were used to drive the hydrodynamic hydrological model and evaluate the effect of different precipitation data in the flash flood simulation.The results showed that: (1) Among the 12-hour cumulative precipitation amounts, CMPA demonstrated higher accuracy in terms of the position of large value areas and differences in local precipitation levels; Radar-QPE was closer to AWS (Automatic Weather Station) in terms of cumulative precipitation level but showed significant differences in spatial distribution; FY4B-QPE overestimated the cumulative precipitation level by 33.8%.(2) In terms of hourly distribution, CMPA was most similar to AWS in terms of temporal evolution, spatial distribution, and precipitation level; Radar-QPE's peak values were smaller, and the peak times were lagged, with negative deviations in precipitation being dominant; FY4B-QPE's peak values and peak times were consistent with reality, but there were deviations in the start and end times of precipitation, with positive deviations in precipitation being dominant.(3) In the hydrological simulation study, CMPA, Radar-QPE, and FY4B-QPE all overestimated water levels, but the timing of water level peaks was more consistent with AWS.CMPA performed best in terms of RMSE (Root Mean Square Error), NSE (Nash Efficiency Coefficient), and Bias (Relative Deviation), followed by Radar-QPE, and FY4B-QPE performed relatively poorly.Although existing site-observed precipitation cannot fully meet the needs of research and early warning for small and medium scale mountain floods, the high precision of CMPA data could effectively supplement the deficiencies of traditional meteorological observation stations to some extent.Meanwhile, the algorithms and accuracy of Radar-QPE and FY4B-QPE needed to be further improved and enhanced.…”

A Deep Learning-Based Echo Extrapolation Method by Fusing Radar Mosaic and RMAPS-NOW Data
Published 2025-07-01“…Furthermore, as the extrapolation time increases, the smoothing effect inherent to convolution operations leads to increasingly blurred predictions. To address the algorithmic limitations of deep learning-based echo extrapolation models, this study introduces three major improvements: (1) A Deep Convolutional Generative Adversarial Network (DCGAN) is integrated into the ConvLSTM-based extrapolation model to construct a DCGAN-enhanced architecture, significantly improving the quality of radar echo extrapolation; (2) Considering that the evolution of radar echoes is closely related to the surrounding meteorological environment, the study incorporates specific physical variable products from the initial zero-hour field of RMAPS-NOW (the Rapid-update Multiscale Analysis and Prediction System—NOWcasting subsystem), developed by the Institute of Urban Meteorology, China. …”
