Abstract: This paper presents a bionic autonomous learning method based on operant conditioning automata,and designs a cognitive model of Skinner operant conditioning automata.The model adds a unit of behavior propensity to generate learning mechanism of 'reaction-strengthening',and simulates nature biotic randomly compliance.A recursive learning algorithm is proposed,which is to simulate biotic operant conditioning mechanism and let it have bionic self-organization function including self-learning function and self-adaptive function.Finally,the model is proved to have the bionic self-learning ability and can be used to descript,simulate,and design various self-organizing systems.
