摘要

•Effective strategies for band selection and feature extraction.•A novel semi-supervised deep neural network regression (Semi-DNNR) model.•The performance of semi-DNNR is better than PLSR and SVR.•Hydrological analysis for spatial adsorption and transportation of the soil components.•The correlation and mechanism analysis between soil organic matter and arsenic.
