Memristor-Based Affective Associative Memory Circuit With Emotional Transformation

Most affective associative memory neural networks based on memristor only consider learning and forgetting processes of emotions and the transformation between emotions is ignored. Based on the biological principles of Pavlov associative memory and dual-pathway emotional learning, this paper designs a memristive affective associative memory neural network circuit with emotional transformation and temporary forgetting. In the circuit, the activation and saturation characteristics in biological affective system are also considered. The circuit is composed of input neuron module, voltage control module, synapse module and output neuron module. The circuit can realize the direct and gradual transformation between different emotions and temporary forgetting and is verified by simulation. The designed circuit may develop the association between biological theories and memristive circuit implementations and provide a reference for further development of brain-like systems.
