Differentiation of yeast-inoculated and uninoculated tomatoes using fluorescence spectroscopy

Artificial-intelligence-based analysis methods can provide objective and accurate results. This study aimed to evaluate the performance of machine learning algorithms to classify yeast-in-oculated and uninoculated tomato samples using fluorescent spectroscopic data.

For this purpose, three different tomato types were used: 'local dwarf', 'Picador', and 'Ideal'. Discrimination analysis was applied with six different machine learning (ML) algorithms. Confusion matrices, average accuracies , F-Measure, Precision, ROC (receiver operating characteristic) Area, MCC (Matthews Correlation Coefficient), and precision-recall area values obtained as a result of the application of different ML algorithms were compared.

Based on the fluorescence spectroscopic data, the application of six ML algorithms showed that the first two tomato types were classified with 100% accuracy and the last type was classified with 95% accuracy. The results of the study show that the fluorescence spectroscopy data are strongly representative of tomato species. ML methods fed with these data provide high-performance discrimination.
