“…For the implementation of a pattern recognition ANN, a training phase is required where the data to be learned and the category to which it must be assigned are presented. Then, for the first stage, the EMG signals from the biceps are sampled at three voltage thresholds (Cote-Allard et al, 2019;Hagengruber et al, 2022;Setioningsih, 2021). Figure 3 shows the thresholds distinguished by vertical dotted lines, on the left "low voltage", in the middle "medium voltage" and on the right "high voltage".…”
