Classification performance (original grouped data) of the E-tongue-LDA-SA model (28 selected sensors): discrimination of olive oils according to the heat-induced cooking process (group 1: unheated olive oil plus oven heating for 15 to 60 min and microwave heating for 1.5 to 3 min; group 2: microwave heating for 5 min; and group 3: microwave heating for 10 min).
