本页介绍了如何创建和管理反洗钱 AI 预测结果。预测结果会保存到 BigQuery 表中。
如需详细了解预测结果的内容,请参阅了解预测输出。
准备工作
-
如需获得创建和管理预测结果所需的权限,请让您的管理员为您授予项目的 Financial Services Admin (
financialservices.admin
) IAM 角色。 如需详细了解如何授予角色,请参阅管理对项目、文件夹和组织的访问权限。 - 创建实例
- 创建模型
- 创建数据集
创建预测结果
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,并会返回一个 Operation 对象;如需了解详情,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,请发送请求,然后检查结果。通常,所有 POST、PUT、UPDATE 和 DELETE 操作都是长时间运行的操作。
