The Research Of Memory Models Based On Attribute Topology

In recent years,with the rise of cognitive computing,the concept as the basic unit of cognition has been paid more and more attention.In the research of various concept representations,formal concept analysis as the main method of formal concept representation has been widely concerned.At the same time,the concept comes from the combination of memory materials.Therefore,the study of memory model has been paid attention to the subject of biology,psychology,cognitive science and so on,meanwhile,has achieved a certain development.However,there is no relevant research report in the field of formal concept analysis.Therefore,this paper designs a memory model for concept calculation based on attribute topology which is the new method of formal concept analysis,and lays a foundation for dynamic concept calculation.Firstly,the memory model of attribute topology is proposed.The model is based on the graph characteristics and computing ability of attribute topology in addition integrates the characteristics of existing memory models.This model provides a basic framework for attribute topology simulated memory mechanism.Secondly,this paper proposes a memory activation algorithm based on the memory model of attribute topology.From the perspective of memory activation,the algorithm analysis the basic method of attribute topology simulates the memory activation process in detail.The related concept and algorithm of attribute topology of memory activation are proposed in this paper,furthermore,the rationality of the memory activation algorithm and its cognitive significance are proved by experiments.Finally,a memory forgetting algorithm based on the attribute topology memory model is proposed in this paper.From the perspective of memory forgetting,the related concepts of attribute topology forgetting process is proposed by analyzing various memory models such as Ebbinghaus forgetting curve and combining the characteristics of attribute topology.In addition,it is noted that the characteristics of attribute grading in the process of fogetting and the same attribute node show difference when it receive the stimulus from different new object and other phenomena during the forgetting process.A memory forgetting algorithm based on attribute topology is proposed,meanwhile,simulation of forgetting process through the three-dimensional image is achieved.The experimental results show that the attribute topology forgetting algorithm conforms to the forgotten process of the human brain,and it is feasible to simulate the brain forgetting process based on attribute topology.The experimental process also accords with the forgotten law of the human brain.
