Measuring the wind vane of Success by Momentum based on PCA

Abstract

Tennis is a sport favored and admired by countless number of people throughout the world, which comprises two playing styles: singles and doubles. The paper presents a quantitative definition of the “momentum” and constructs two models regarding “momentum” and performance through analyzing various factors in the matches. We divide the given data into the training set and the testing set, and extract useful information under each point. Then, through analyzing various factors comprising serve counts, situation of ace and so on, conduct the dimensionality reduction utilizing PCA. Then we classify the performance of players per point into three key factors: endurance performance, serving performance and scoring performance and give the corresponding evaluation standard. Finally we utilize our models and analysis of the result, we present several related suggestions for coaches and players.
