Visual number sense for real-world scenes shared by deep neural networks and humans

Description

This study investigated the number perception of scenes using AlexNet. The study findings show that numerosity can be represented by the pattern of group activation of the category layer units. We believe that our study makes a significant contribution to the literature because it is the first to show that a distinct feature in visual environments, revealed by deep neural networks, can modulate human numerosity perception, supported by a group-coding mechanism.
