个性化适配技术已广泛应用于健康、培训教育、电子商务、娱乐等数字化应用领域。个性化系统通常会构建一个用户模型，旨在描述当前用户的特征，然后使用该模型来个性化交互。然而，个性化和用户建模通常在本质上是相互矛盾的（这一事实有时被称为个性化悖论）。在本文中，我们仔细研究了这种个性化悖论，并确定了它可能表现出来的两种方式：反馈循环和移动目标。为了说明这些问题，我们报告了个性化运动游戏（用于体育锻炼的视频游戏）领域的结果，并描述了我们解决个性化悖论引起的一些问题的早期步骤。
Personalized adaptation technology has been adopted in a wide range of digital applications such as health, training and education, e-commerce and entertainment. Personalization systems typically build a user model, aiming to characterize the user at hand, and then use this model to personalize the interaction. Personalization and user modeling, however, are often intrinsically at odds with each other (a fact some times referred to as the personalization paradox). In this paper, we take a closer look at this personalization paradox, and identify two ways in which it might manifest: feedback loops and moving targets. To illustrate these issues, we report results in the domain of personalized exergames (videogames for physical exercise), and describe our early steps to address some of the issues arisen by the personalization paradox.
