虽然理论上对手建模在任何对抗领域都很有用，但实际上很难准确地做到并且有效地用来改进游戏。在这个视频中，我们提出了一种在线对手建模的方法，并说明如何在Rush 2008足球比赛中使用它来提高进攻性能。在足球中，团队行为具有可观察的时空结构，由团队成员随时间的相对身体位置定义;我们证明了这种结构可以利用监督学习方法在戏剧的早期阶段识别足球比赛。根据球队的比赛历史，我们的系统根据其他比赛的潜力评估执行比赛开关的竞争优势，以增加所获得的码数和候选比赛与当前比赛的相似性。在这个视频中，我们研究了两种类型的播放开关：1）整个团队和2）子组。两种类型的游戏开关都可以改善进攻性能，但是只改变进攻球员关键子组的行为可以获得更大的码数增加。

Although in theory opponent modeling can be useful in any adversarial domain, in practice it is both difficult to do accurately and to use effectively to improve game play. In this video, we present an approach for online opponent modeling and illustrate how it can be used to improve offensive performance in the Rush 2008 football game. In football, team behaviors have an observable spatio-temporal structure, defined by the relative physical positions of team members over time; we demonstrate that this structure can be exploited to recognize football plays at a very early stage of the play using a supervised learning method. Based on the teams' play history, our system evaluates the competitive advantage of executing a play switch based on the potential of other plays to increase the yardage gained and the similarity of the candidate plays to the current play. In this video, we investigate two types of play switches: 1) whole team and 2) subgroup. Both types of play switches improve offensive performance, but modifying the behavior of only a key subgroup of offensive players yields greater improvements in yardage gained.
