基于贝叶斯群学习的职业篮球运动员投篮选择

Bayesian Group Learning for Shot Selection of Professional Basketball Players

Guanyu Hu, Hou-Cheng Yang, Yishu Xue

摘要:

在本文中,我们开发了一个小组学习的方法来分析潜在的异质性结构的投篮选择在NBA的职业篮球运动员。基于对数高斯-考克斯过程(LogGaussian-Cox process,LGCP),提出了一种有限混合物混合模型(MFM)来刻画不同球员投篮选择的异质性。我们所提出的方法可以同时估计组的数量和组配置。提出了一种有效的马尔可夫链蒙特卡罗(MCMC)算法。已经进行了模拟研究,以证明其性能。最终,我们提出的学习方法在分析NBA 2017-2018常规赛几名球员的投篮图中得到了进一步的说明。

英文摘要:

In this paper, we develop a group learning approach to analyze the underlying heterogeneity structure of shot selection among professional basketball players in the NBA. We propose a mixture of finite mixtures (MFM) model to capture the heterogeneity of shot selection among different players based on Log Gaussian Cox process (LGCP). Our proposed method can simultaneously estimate the number of groups and group configurations. An efficient Markov Chain Monte Carlo (MCMC) algorithm is developed for our proposed model. Simulation studies have been conducted to demonstrate its performance. Ultimately, our proposed learning approach is further illustrated in analyzing shot charts of several players in the NBA's 2017-2018 regular season.
