Tóm tắt

Low-cost sensors (LCSs) can address gaps in regulatory air quality monitoring station (AQMS) distribution, but they face data quality issues and spatial misalignment challenges when calibrating large-scale LCS networks against AQMS networks. This study proposed a semi-supervised learning model that uses data augmentation via chained imputation (CI-DA) to address the spatial misalignment problem by synthesizing pseudo-LCS data, thereby enhancing the use of LCS in PM
