Brain-like Initial-boosted Hyperchaos and Application in Biomedical Image Encryption
Lin, Hairong; Wang, Chunhua; Cui, Li; Sun, Yichuang; Xu, Cong; Yu, Fei (2022-03-03)Neural networks have been widely and deeply studied in the field of computational neurodynamics. However, coupled neural networks and their brain-like chaotic dynamics have not been noticed yet. This paper focuses on the ... -
An Extremely Simple Multi-Wing Chaotic System: Dynamics Analysis, Encryption Application and Hardware Implementation
Lin, Hairong; Wang, Chunhua; Yu, Fei; Xu, Cong; Hong , Qinghui; Yao, Wei; Sun, Yichuang (2020-12-31)Polynomial functions have been the main barrierrestricting the circuit realization and engineering applicationof multi-wing chaotic systems (MWCSs). To eliminate thisbottleneck, we construct a simple MWCS without ... -
Memristor-Based Affective Associative Memory Neural Network Circuit with Emotional Gradual Processes
Liao, Meiling; Wang, Chunhua; Sun, Yichuang; Lin, Hairong; Xu, Cong (2022-04-01)In the existing affective associative memory neural network circuits, the change of emotions in the affective associative learning and forgetting processes is abrupt and the intensity of emotions is invariable. In fact, ... -
Memristor-based neural network circuit with weighted sum simultaneous perturbation training and its applications
Xu, Cong; Wang, Chunhua; Sun, Yichuang; Hong , Qinghui; Deng, Quanli; Chen, Haowen (2021-08-20)In this work, a full circuit of memristor-based neural network with weighted sum simultaneous perturbation training is proposed.
