下面哪项 Google Analytics 功能依靠 Google AI 和机器学习来衡量您无法直接观测到的转化？

The "Modeled conversions" feature (根据模型估算关键事件) uses Google AI and machine learning to estimate conversions that cannot be directly observed due to privacy restrictions or technical limitations (e.g., cookie consent, ad blockers). This provides a more complete picture of conversion performance. "Conversion windows" (转化时间范围) define the period after an ad interaction during which a conversion is recorded, but don't involve AI for unobserved conversions. "Conversion events" (转化事件) are specific user actions tracked as conversions, but the feature itself doesn't use AI for modeling. "Attribution paths" (归因路径) show the sequence of touchpoints leading to a conversion, which is a reporting feature, not a modeling one for unobserved conversions.
