• Title: Estimating NBA players salary share according to their performance on court: A machine learning approach
• Authors: Ioanna Papadaki and Michail Tsagris
• Abstract summary: It is customary for researchers and practitioners to fit linear models in order to predict NBA player's salary based on the players' performance on court. We focus on the players salary share by first selecting the most important determinants or statistics. We then utilise them to predict the player salaries by employing a non linear Random Forest machine learning algorithm.

• Abstract: It is customary for researchers and practitioners to fit linear models in order to predict NBA player's salary based on the players' performance on court. On the contrary, we focus on the players salary share (with regards to the team payroll) by first selecting the most important determinants or statistics (years of experience in the league, games played, etc.) and then utilise them to predict the player salaries by employing a non linear Random Forest machine learning algorithm. We externally evaluate our salary predictions, thus we avoid the phenomenon of over-fitting observed in most papers. Overall, using data from three distinct periods, 2017-2019 we identify the important factors that achieve very satisfactory salary predictions and we draw useful conclusions.

  We propose a robust model training and evaluation framework to mitigate label variance and extremes. Within this framework, we introduce a collaborative-enhanced model designed to predict user game spending without relying on user IDs. Our approach demonstrates notable improvements over production models, achieving a remarkable textbf17.11% enhancement on offline data.
