Abstract

En 中文

• After grouped validation and hyperparameter optimization, XGBoost achieved a mean test R2 of 0.77 for composting time. • Cooling–maturation-phase cumulative temperature had the greatest contribution to the model output for composting time. • SEM showed the strongest pathfor cooling–maturation-phase cumulative temperature with composting time (β = 0.80, p < 0.001).
