based model than either electronic tongue or electronic nose
alone. These results demonstrated that LLE algorithm coupled
with SVM or KNN for the combined electronic signals was
effective in extracting and analyzing features for detecting
rice. Compared with the KNN model, the SVM model
achieved a little higher accuracy. It was believed that the
combination of electronic tongue and nose coupled with
LLE-based model had a great potential in the prediction of
rice types.
electronic tongue alone, however, lower than that for single
electronic nose alone. It was demonstrated that the developed
electronic tongue combined with electronic nose system possessed
more accuracy prediction of rice variety with the LLE
