A review of three-way decisions based on machine learning
Three-way decision(3 WD)is an important research direction in the field of granular computing,which conforms to human thinking and can effectively deal with uncertainty problems in practical decision-making processes.Three-way decision can effectively reduce the cost of decision-making,enhance the control of uncertain decision-making processes and improve the interpretability of model by introducing delay strategy.Therefore,a three-way decision based on machine learning is worth researching deeply.Firstly,the basic model of three-way decision is introduced.Secondly,the research status of three-way decision based on machine learning at domestic and foreign search results is analyzed by using CiteSpace and VOSviewer.Thirdly,from the perspectives of research questions,model methods,and application backgrounds,the integration of three-way decisions with clustering models,classification models,recommendation systems,and deep learning models are focused on.Finally,the future research directions of three-way decisions based on machine learning are given.
