Abstract

This paper focuses on a model that can capture match points in real time, record the scoring flow during the match, and determine the highlight moment of each player in real time. We apply this model to one or more competitions to better optimize the model by varying the proportion of weight factors and introducing more complex factors to adjust the value of momentum. Statistical distribution fitting as well as the Pearson correlation coefficient were used to assess the correlation between player momentum and match outcome, thus assessing the stochasticity of the transition between momentum and match situations. Using the random forest distribution algorithm to predict the turning point and evaluate the generalizability of the model gives a reasonable scheme. This article constructs two mathematical models for calculating momentum: a basic model and an optimized and improved model, to obtain the relationship between score and momentum in the game. In the basic model, this article sets up a function model to solve the problem under hypothetical conditions. Introduce weight parameters to adjust the degree of impact of winning or losing on momentum. But there are more complex factors, so we changed the function model to a state space model.
