Analysis of Factors Influencing the Number of Olympic Medals Based on Shap Importance Ranking and Machine Learning Algorithm
Year: 2025
Type: article
Abstract: This paper innovatively combines the SHAP method and the random forest model to focus on the study of factors influencing the number of Olympic medals, aiming at identifying the key influencing factors and clarifying their effects. The study analyzes the importance of the factors through Random Forest, explains the specific influence mechanism of each factor with the help of SHAP values, and further quantifies and describes the influence effect by using grey prediction and double difference method. The findings of the study not only reveal the core factors affecting the number of Olympic medals and their effect paths but also provide methodological reference and empirical evidence for related studies in the field of sports, which is of practical significance for optimizing Olympic preparation strategies.
