Expectation Maximization seeded with players’ self-assessments for their motivations was run for two different model types &mdash; Naive Bayes and a trigram model &mdash; to uncover three clusters each. For both model structures, most players were classified as belonging to a single large cluster that combined the goals of splashy plays, clever combos, and effective play, cross-cutting the original categories &mdash; a cautionary tale for research that assumes players can be classified into one category or another. However, subjects qualitatively report that the different model structures play very differently, with the Naive Bayes model more creatively combining cards. </p> }, number={1}, journal={Proceedings of the AAAI Conference on Artificial Intelligence and Interactive Digital Entertainment}, author={Gold, Kevin}, year={2011}, month={Oct.}, pages={140-145} }
