Water Quality Estimation Through Machine Learning Multivariate Analysis
This addresses water safety and regulatory compliance in agriculture and food processing, but it is incremental as it applies existing machine learning and interpretability techniques to a specific domain.
The paper tackled the problem of automatic water quality assessment for the agrifood sector by integrating UV-Vis spectroscopy with machine learning, resulting in a rapid, accurate, and interpretable method for estimating key parameters.
The quality of water is key for the quality of agrifood sector. Water is used in agriculture for fertigation, for animal husbandry, and in the agrifood processing industry. In the context of the progressive digitalization of this sector, the automatic assessment of the quality of water is thus becoming an important asset. In this work, we present the integration of Ultraviolet-Visible (UV-Vis) spectroscopy with Machine Learning in the context of water quality assessment aiming at ensuring water safety and the compliance of water regulation. Furthermore, we emphasize the importance of model interpretability by employing SHapley Additive exPlanations (SHAP) to understand the contribution of absorbance at different wavelengths to the predictions. Our approach demonstrates the potential for rapid, accurate, and interpretable assessment of key water quality parameters.
