Commentary on Cognitive science as a theory of living systems:On the philosophy of subtraction and contraction by Takashi Ikegami

Abstract

Ikegami considers that cognitive systems are constantly exposed to excess observational data, from which it acquires the subtractive representations rather than the contractions that deep learning aims for. Furthermore, he argues that a glimpse of life as the basic principle of cognition can be seen in the moment when the contraction collapses. The current commentary discusses these points by making possible correspondences to the cognitive robotics studies conducted by the author and his colleagues.
