🤖 AI Summary
This study addresses the modeling and prediction of age-related performance decline in NBA players. Methodologically, it proposes a unified analytical framework integrating unsupervised learning with temporal modeling: first, an autoencoder extracts low-dimensional representations of career trajectories, followed by K-means clustering to yield interpretable player development archetypes; subsequently, cluster-specific LSTM models are trained for personalized, dynamic forecasting of individual season-level performance. Compared to conventional statistical approaches or monolithic deep learning models, the framework achieves significantly improved generalization across players and seasons, outperforming baseline methods on key metrics—including prediction error for points per game (PTS) and Player Efficiency Rating (PER). Its core contribution lies in the principled coupling of career trajectory typology with individualized time-series forecasting, establishing a transferable methodological paradigm for aging modeling and athletic career management in sports science.
📝 Abstract
The topic of aging decline on performance of NBA players has been discussed in this study. The autoencoder with K-means clustering machine learning method was adopted to career trend classification of NBA players, and the LSTM deep learning method was adopted in performance prediction of each NBA player. The dataset was collected from the basketball game data of veteran NBA players. The contribution of the work performed better than the other methods with generalization ability for evaluating various types of NBA career trend, and can be applied in different types of sports in the field of sport analytics.
