Nondestructive Detection of Soluble Solids Content in Navel Orange Based on GEP Algorithm

Abstract:

A rapid quantification technique was developed and validated for nondestructively quantifying the soluble solids content of navel orange using NIR spectroscopy in conjunction with Gene expression programming (GEP) algorithm and genetic algorithm (GA).The spectra were recorded in the NIR region using the fiber optic probe method. Four data points of the navel orange NIR spectra were selected by GEP algorithm and genetic algorithm by cross validation. In our experiment, the mean standard error R_i between the prediction values and the real values in the train group is 0.0256, and the validation group is 0.0194, the results show that the proposed method can be built to a concise easily computed model, which has higher accuracy.
