Predicting Matchups and Preferences in Context

Shuo Chen, Thorsten Joachims
2016 Proceedings of the 22nd ACM SIGKDD International Conference on Knowledge Discovery and Data Mining - KDD '16  
Unlike existing models for these tasks, our model not only learns representations of the items in a more expressive latent vector space, but also models how context modifies matchup and preference outcomes  ...  We present a general probabilistic framework for predicting the outcome of pairwise matchups (e.g. two-player sport matches) and pairwise preferences (e.g. product preferences), both of which have widespread  ...  Acknowledgments We thank Arzoo Katiyar and Yexiang Xue for their valuable suggestions and advice. This research was funded in part through NSF Awards IIS-1247637, IIS-1217686, and IIS-1513692.  ...

Broadcaster Choice and Audience Demand for Live Sport Games: Panel Analyses of the Korea Baseball Organization

Kihan Kim, Hojun Sung, Yeayoung Noh, Kimoon Lee
2021 Journal of Sport Management  
Broadcasters' choice order of matches and the actual television ratings of each match were regressed on a series of antecedent factors related to the game characteristics and audience preferences.  ...  It also appeared that broadcasters' choices were based on popularity and team performance/quality, whereas viewers showed preference for current games' on-field performance.  ...  Thus, further investigation is needed to reveal fan preferences in various contexts, as Fort (2017) noted.  ...

Modeling Intransitivity in Matchup and Comparison Data

Shuo Chen, Thorsten Joachims
2016 Proceedings of the Ninth ACM International Conference on Web Search and Data Mining - WSDM '16  
We show that our model can represent any pairwise stochastic preference relation and provide a comprehensive evaluation of its predictive performance on a wide range of pairwise comparison tasks and matchup  ...  We present a method for learning potentially intransitive preference relations from pairwise comparison and matchup data.  ...  We explore datasets ranging from online video games and sports to peer grading and election, finding that the new model provides improved prediction accuracy on several tasks, especially in the domain  ...

SEAM methodology for context-rich player matchup evaluations [article]

Charles Young, David Dalpiaz, Daniel J. Eck
2020 arXiv   pre-print
We develop the SEAM (synthetic estimated average matchup) method for describing batter versus pitcher matchups in baseball, both numerically and visually.  ...  Many individual matchups have a sample size that is too small to be reliable. Synthetic versions of the batter and pitcher under consideration are constructed in order to alleviate these concerns.  ...  We would also like to thank Alan Nathan, Jim Albert, James Balamuta, Dootika Vats, John Marden, and Dave Zhao for helpful comments that improved our article and our Shiny app.  ...
