Memristive circuit of emotion with negative feedback based on three primary color model☆

Many memristive circuits tend to oversimplify the process of emotion generation as a linear event, disregarding crucial factors such as negative feedback and other regulatory mechanisms. In this paper, a memristive circuit of emotion with negative feedback based on three primary color model is proposed to solve the above problems. The designed circuit is composed of perception modules, synapse modules, central nervous system modules and overt behavior module. It realizes emotion generation, emotion evolution and long-term memory functions based on the neural network circuit with behavioral homeostatic negative feedback function. Meanwhile, the three primary color model of basic emotions is discussed and realized. Any two basic emotions can be mixed to produce a higher order emotion. The memristive circuit, based on the three primary color model as a theoretical foundation, offers valuable insights for the further advancement of neural networks.
