Five examples of umami taste predictors are instead present in recent literature, namely, iUmami-SCM , UMPred-FRL , VirtuousUmami , Umami-MRNN , and Umami-BERT . From a technical point of view, several ML algorithms are used for taste prediction, among which Multiple Linear Regression (MLR) and Support Vector Machine (SVM) were the first used models for binary classification .
