The development of deep learning consequently occurred parallel to the study of artificial intelligence, and especially neural networks. After beginning in the 50 s, it is mainly in the 80s that this area grew, thanks to Geoff Hinton and machine learning specialists who collaborated with him. In those years, computer technology was not sufficiently advanced to allow a real improvement in this direction, so we had to wait until the present day to see, thanks to the availability of data and the computing power, even more significant developments.
