“…These four requirements do not assure good quality of data, but they are the minimal characteristics required to test our approaches. No dataset with the four characteristics was found, some of the explored datasets were: IEMO-CAP, Enterface [42], Mosei [43], SEMAINE [44], MOSI [45], MOUD [46], MELD [47], Humaine [48,49], CK [50], CK+ [51], DEAP [52], AMIGOS [53,54], AFEW-VA [13]. Thus, it was decided to look for unimodal datasets that meet these requirements and as far as possible that they reflect the real conditions of virtual education, with the objective of fusing them for creating an artificial dataset that have the required features.…”
