ABSTRACT In this study, a hybrid black‐ and white‐box machine learning (ML) framework is proposed for matric suction estimation in compacted fine‐grained soils, utilizing ML techniques, namely, particle swarm optimized support vector regression (PSO‐SVR) multi‐gene genetic programming (MGGP). This objective achieved through developing novel ML‐based method designing requisite soil parameters, including new parameter, the “effective degree of aggregation”. parameter captures influence varying structures associated with different initial water content conditions soils estimating suction. Additionally, sensitivity analyses are performed to better understand significance effective aggregation other critical properties. Explicit equations derived from MGGP models, enabling their use using spreadsheets alleviating reliance on complex tools. The models promising prediction hydro‐mechanical behavior related properties, facilitating application conventional geotechnical engineering practice.
