A deep neural network tracks tool proficiency development.

Abstract

DeepLabCut, a deep-learning-based network for markerless pose estimation, has been used to track the acquisition and development of tool use in a nontool-using corvid species. This development has the potential to lead to new lines of research understanding how tool and motor expertise develop at the behavioral, neural, cognitive, and evolutionary level.
