“…The data available were further compiled, grouping the results according to the model. The most used machine learning approach was FFNN, representing eight of the analyzed articles [32,34,36,40,41,43,44,49]. The second most published approach, with three articles [30,31,38], was LSTM, and the remaining eleven studies were dispersed over a variety of models, therefore grouped as "other" [27][28][29]33,35,37,39,42,[45][46][47][48].…”
