Abstract

En 中文

• Non-destructive origin traceability of three varieties of FFRMs was proposed. • Two variable selection-RF methods were developed. • Both characteristic variables and feasible traceability models were obtained. • Optimization of the integration time can improve the models in some cases. • RT demonstrated higher robustness, while SPA can simplify RF model.
