创建和管理回测结果

本页介绍了如何创建和管理 AML AI 回测预测结果。回测预测会使用针对现有历史数据训练的模型。在这些月份内,数据集必须包含存在可疑活动或调查开始日期(导致 AML_EXIT 事件)的相关方。如需详细了解 AML AI 如何为各种相关方分配标签,请参阅风险案例的生命周期

相同的数据集可用于训练和回测,前提是训练 结束日期早于回测日期。

准备工作

创建回测结果

某些 API 方法会返回长时间运行的操作 (LRO)。这些方法是异步的,并返回 Operation 对象;有关详情,请参阅 REST 参考文档。当方法返回响应时,操作可能尚未完成。对于这些方法,请将 然后查看结果一般来说,所有 POST、PUT、UPDATE 和 DELETE 操作 长期运行

发送请求

如需创建回测结果,请使用 projects.locations.instances.backtestResults.create 方法。

在使用任何请求数据之前,请先进行以下替换:

  • LOCATION:实例的位置;请使用某个受支持的地区
    显示营业地点

  • PARTY_INVESTIGATIONS_PER_PERIOD_HINT: 一个数字,用于提示调谐器根据此数据要调查的派对数 每期(每月)。这用于控制模型的评估方式。例如,首次尝试使用 AML AI 时,我们建议您根据现有自动提醒系统发出的提醒,将此值设置为平均每月调查的相关方数量。
