Machine learning-aided reliability analysis of rainfall-induced landslide of root-reinforced slopes
Bibliographic record
Abstract
Estimating the failure probability of rainfall-induced landslides is often challenging as the triggering mechanism is influenced by a number of parameters whose uncertainty is difficult to quantify and, in practice, is neglected. The reinforcing effect of vegetation on natural slopes adds to the complexity of the stability analysis. In this study, we present the application of a coupled hydro-mechanical model for the effect of plant roots on soil shear strength. First, a deterministic approach is adopted. Then, a reliability analysis of a root-reinforced slope subjected to rainfall is performed by considering the inherent variability of the soil and root properties. The probability of failure is estimated with machine learning surrogate models, which approximate the nonlinear relationship between constitutive parameters and slope displacements at different time steps. The machine learning algorithms are trained on a small dataset. The extreme gradient boosting is the best-performing algorithm with R2 ≥ 0.975 and is then employed to estimate the probability of failure on a larger dataset of one million datapoints with higher accuracy.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
