April 18, 2013 — Georgia Tech researchers have developed a computational model that can predict video game players’ in-game performance and provide a corresponding challenge they can beat, leading to quicker mastery of new skills. The researchers used a method called collaborative filtering, a popular technique employed by Netflix and Amazon in product ratings and recommendations. While Netflix recommends movies, the gaming model recommends the next challenge for players, adjusting game difficulty by computationally forecasting in-game performance.
