“…This model achieved an accuracy rate of 49.95% and an AUC31 of 0.71 for the five basic tastes . In addition to EEG data, You Wang used differential electrodes to detect facial and chewing muscles to obtain surface electromyography (sEMG) and further achieved an accuracy rate of 74.46% by random forest algorithm . Romeo-Arroyo employed a decision tree to process data from multiple sub-brain regions to achieve a 79% discriminating accuracy for distinct stimuli (“sweet” vs “nonsweet” odors; “sweet-taste”, “sweet-flavor”, and “nonsweet flavor”; and “sweet stimuli” vs “nonsweet stimuli”) …”
