Recently, Professor Su Shuhua of the School of Mathematics, Physics and Statistics guided Tu Jing, a postgraduate student majoring in statistics of grade 2021, to publish a paper entitled "A novelgrey relational clustering model under sequential three-way decision framework" on the Top journal of artificial intelligence "Information Sciences" (District 1, CAS). IF=8.1).
In this paper, they use statistics, management science, data science and other relevant methods, take complex dynamic information system as the research object, and design a grey relational clustering model integrating sequential three-branch decision by giving a new method to calculate conditional probability and threshold, and verify the effectiveness and feasibility of the model, on this basis, the model is applied to the portfolio field. This work provides an effective method for the decision making and portfolio strategy construction of information systems that lack decision attributes or class labels.
