论文摘要
每年,游戏行业花费大约150亿美元的营销再投资。但是,这个数量是不考虑玩家的技能和运气的任何考虑因素。对于赌场而言,一个非熟练的球员的收入比熟练的球员高出约4倍。本文介绍了基于蒙版R-CNN模型扩展的视频识别系统。我们的系统通过实时检测卡和玩家的赌注来数字化二十一点游戏,并处理他们做出的决策以创建准确的玩家角色。我们提出的监督学习方法包括一条专业的三阶段管道,该管道从赌场表的两个观点中获取图像,并进行实例细分以生成对拟议的感兴趣区域的口罩。这些预测的掩码以及衍生功能用于对传递到下一阶段的图像属性进行分类,以吸收游戏玩法的理解。我们的端到端模型的主要BET检测的准确性约为95%,在使用转移学习方法培训的受控环境中,使用900个培训示例的受控环境中的卡片检测〜97%。我们的方法是可推广和可扩展的,并且在各种游戏方案和测试数据中显示出令人鼓舞的结果。这样的粒状水平收集了数据,有助于了解玩家与最佳策略的偏差,从而将玩家的技能与游戏运气分开。我们的系统还通过将玩家的投注模式与甲板的缩放计数相关联,评估了卡计数的可能性。这样的系统允许赌场标记欺诈活动,并计算每个玩家的预期个性化盈利能力,并量身定制其营销再投资决策。
Annually the gaming industry spends approximately $15 billion in marketing reinvestment. However, this amount is spent without any consideration for the skill and luck of the player. For a casino, an unskilled player could fetch ~4 times more revenue than a skilled player. This paper describes a video recognition system that is based on an extension of the Mask R-CNN model. Our system digitizes the game of blackjack by detecting cards and player bets in real-time and processes decisions they took in order to create accurate player personas. Our proposed supervised learning approach consists of a specialized three-stage pipeline that takes images from two viewpoints of the casino table and does instance segmentation to generate masks on proposed regions of interest. These predicted masks along with derivative features are used to classify image attributes that are passed onto the next stage to assimilate the gameplay understanding. Our end-to-end model yields an accuracy of ~95% for the main bet detection and ~97% for card detection in a controlled environment trained using transfer learning approach with 900 training examples. Our approach is generalizable and scalable and shows promising results in varied gaming scenarios and test data. Such granular level gathered data, helped in understanding player's deviation from optimum strategy and thereby separate the skill of the player from the luck of the game. Our system also assesses the likelihood of card counting by correlating the player's betting pattern to the deck's scaled count. Such a system lets casinos flag fraudulent activity and calculate expected personalized profitability for each player and tailor their marketing reinvestment decisions.
