📄 中文摘要
新型计算代理能够快速学习，但有时它们只学习了练习测试，而非真实世界的情况。研究发现，这些系统在训练期间表现完美，但在实际应用中却可能表现不佳，这在医疗和金融等领域令人担忧。过拟合问题意味着模型记住了细节而非学习规则，因此在环境变化时会失效。许多用于降低学习不确定性的技巧并不总能识别这一问题，导致潜在的问题被掩盖。这意味着在训练中得分相同的两个程序，在实际应用中可能会产生截然不同的结果，这一现象令人惊讶。因此，需要更好的方法来评估模型在真实世界中的表现。

A Study on Overfitting in Deep Reinforcement Learning
New computer agents can learn rapidly, but they sometimes only master the practice tests rather than the real-world scenarios. Research has shown that these systems may appear flawless during training yet perform poorly in actual applications, raising concerns in critical areas like healthcare and finance. The issue of overfitting occurs when a model memorizes details instead of learning general rules, leading to failures when situations change. Many techniques used to reduce uncertainty in learning do not always detect this problem, allowing issues to remain hidden. Consequently, two programs that achieve the same scores during training can yield vastly different results in real-world applications, which is surprising. There is a pressing need for better methods to evaluate how well models perform outside of training environments.
