变精度模型构建的知识结构
Knowledge Structures Delineated by Variable Precision Models
摘要
Abstract
The construction of knowledge structures is a focal point in the knowledge space theory.The α-variable precision model ef-fectively integrates the disjunctive and conjunctive models to construct knowledge structure.This paper proposes three types of y-variable precision models based on the α-variable precision model,explores the properties of the knowledge structures they con-struct,and investigates the relationships among the four types of variable precision models.Furthermore,we develop a matrix meth-od based on variable precision models to construct knowledge structures by studying the relationship between matrix multiplication and skill inclusion degree and design a corresponding algorithm.Finally,seven datasets are selected for experimentation to compare the performance of the algorithm in this paper with existing algorithms of variable precision models in constructing knowledge struc-tures.The experimental results show that our algorithm significantly reduces the running time.This advantage is particularly evident when dealing with larger datasets.关键词
