Deep Learning for Air Quality Prediction

Published:Dec 29, 2025 13:58
1 min read
ArXiv

Analysis

This paper introduces Deep Classifier Kriging (DCK), a novel deep learning framework for probabilistic spatial prediction of the Air Quality Index (AQI). It addresses the limitations of traditional methods like kriging, which struggle with the non-Gaussian and nonlinear nature of AQI data. The proposed DCK framework offers improved predictive accuracy and uncertainty quantification, especially when integrating heterogeneous data sources. This is significant because accurate AQI prediction is crucial for regulatory decision-making and public health.
Reference

“DCK consistently outperforms conventional approaches in predictive accuracy and uncertainty quantification.”

Scalable Heterogeneous Treatment Effect Estimation with Propensity Patchwork Kriging

Published:Dec 29, 2025 13:49
1 min read
ArXiv

Analysis

This paper addresses the computational limitations of Gaussian process-based models for estimating heterogeneous treatment effects (HTE) in causal inference. It proposes a novel method, Propensity Patchwork Kriging, which leverages the propensity score to partition the data and apply Patchwork Kriging. This approach aims to improve scalability while maintaining the accuracy of HTE estimates by enforcing continuity constraints along the propensity score dimension. The method offers a smoothing extension of stratification, making it an efficient approach for HTE estimation.
Reference

“The proposed method partitions the data according to the estimated propensity score and applies Patchwork Kriging to enforce continuity of HTE estimates across adjacent regions.”
