训练和测试旨在检测洗钱行为的模型

在本指南中，您将了解如何训练和测试用于检测洗钱行为的模型。您将完成一些基本步骤来准备环境并创建 AML AI 实例。然后，您可以提供 Google 数据集中的合成交易数据（以 BigQuery 表的形式），作为 AML AI 的输入。此输入用于训练和回测模型。

注册要进行预测的方后，该 API 会进行模型预测。结果用于分析一个通过结构化资金进行洗钱的示例实体。

准备工作

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. Install the Google Cloud CLI.

  3. To initialize the gcloud CLI, run the following command: 

    gcloud init

  4. Create or select a Google Cloud project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  5. Make sure that billing is enabled for your Google Cloud project.

  6. Enable the required APIs: 

    gcloud services enable financialservices.googleapis.com bigquery.googleapis.com cloudkms.googleapis.com bigquerydatatransfer.googleapis.com

  7. If you're using a local shell, then create local authentication credentials for your user account: 

    gcloud auth application-default login

    You don't need to do this if you're using Cloud Shell.

  8. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/financialservices.admin, roles/cloudkms.admin, roles/bigquery.admin 

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE
    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:myemail@example.com.

    • Replace ROLE with each individual role.

创建 BigQuery 数据集

本部分介绍了如何创建输入和输出 BigQuery 数据集，然后将银行数据示例复制到输入数据集。

创建输出数据集

创建数据集，用于将 AML 流水线输出发送到该数据集。

Bash

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  my_bq_output_dataset

PowerShell

bq mk `
  --location=LOCATION `
  --project_id=PROJECT_ID `
  my_bq_output_dataset

创建输入数据集

创建一个数据集，将银行示例表复制到其中。

Bash

bq mk \
  --location=LOCATION \
  --project_id=PROJECT_ID \
  my_bq_input_dataset

PowerShell

bq mk `
  --location=LOCATION `
  --project_id=PROJECT_ID `
  my_bq_input_dataset

复制示例数据集

银行数据示例以 BigQuery 数据集的形式提供在 Google 的共享数据集项目中。您必须有权访问 AML AI API，才能访问此数据集。此数据集的主要特点包括：

  • 10 万个相关方
  • 核心时间范围为 2020 年 1 月 1 日至 2023 年 1 月 1 日，以及额外的 24 个月回溯数据
  • 每月 300 个负例和 20 个正例风险信号
  • 具有以下属性的风险信号：
    • 一半的风险信号正例涉及在 AML_PROCESS_START 事件发生前两个月内发生的结构化活动
    • 另一半则涵盖在 AML_PROCESS_START 事件发生前两个月内收到金额最多的相关方
    • 负例是随机生成的
    • 生成风险案例时，出现相反状态的概率为 0.1%（例如，随机生成的相关方为正例，或者相关方存在结构化活动或收入最高，但被报告为负例）
  • AML 架构在 AML 输入数据模型中定义。

  1. 将银行业示例数据复制到您创建的输入数据集。

    Bash

    bq mk --transfer_config \
  --project_id=PROJECT_ID \
  --data_source=cross_region_copy \
  --target_dataset="my_bq_input_dataset" \
  --display_name="Copy the AML sample dataset." \
  --schedule=None \
  --params='{
    "source_project_id":"bigquery-public-data",
    "source_dataset_id":"aml_ai_input_dataset",
    "overwrite_destination_table":"true"
  }'

    PowerShell

    bq mk --transfer_config `
--project_id=PROJECT_ID `
--data_source=cross_region_copy `
--target_dataset="my_bq_input_dataset" `
--display_name="Copy the AML sample dataset." `
--schedule=None `
--params='{\"source_project_id\":\"bigquery-public-data\",\"source_dataset_id\":\"aml_ai_input_dataset\",\"overwrite_destination_table\":\"true\"}'

  2. 监控数据传输作业。

    Bash

    bq ls --transfer_config \
--transfer_location=LOCATION \
--project_id=PROJECT_ID \
--filter="dataSourceIds:cross_region_copy"

    PowerShell

    bq ls --transfer_config `
--transfer_location=LOCATION `
--project_id=PROJECT_ID `
--filter="dataSourceIds:cross_region_copy"

    转移完成后，系统会创建一个显示名称为 Copy the AML sample dataset 的数据传输作业。

    您还可以使用 Google Cloud 控制台查看转移状态。

    您应该会看到类似以下输出的内容。

                         name                           displayName         dataSourceId       state
-------------------------------------------  -----------------------  -----------------  ---------
projects/294024168771/locations/us-central1  Copy AML sample dataset  cross_region_copy  SUCCEEDED

授予对 BigQuery 数据集的访问权限

该 API 会自动在您的项目中创建一个服务账号。服务账号需要对 BigQuery 输入和输出数据集拥有访问权限。

  1. 授予对输入数据集及其表的读取权限。

    Bash

    bq query --project_id=PROJECT_ID --use_legacy_sql=false \
  'GRANT `roles/bigquery.dataViewer` ON SCHEMA `PROJECT_ID.my_bq_input_dataset` TO "serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com"'

    PowerShell

    bq query --project_id=PROJECT_ID --use_legacy_sql=false "GRANT ``roles/bigquery.dataViewer`` ON SCHEMA ``PROJECT_ID.my_bq_input_dataset`` TO 'serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com'"

  2. 授予对输出数据集的写入权限。

    Bash

    bq query --project_id=PROJECT_ID --use_legacy_sql=false \
  'GRANT `roles/bigquery.dataEditor` ON SCHEMA `PROJECT_ID.my_bq_output_dataset` TO "serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com"'

    PowerShell

    bq query --project_id=PROJECT_ID --use_legacy_sql=false "GRANT ``roles/bigquery.dataEditor`` ON SCHEMA ``PROJECT_ID.my_bq_output_dataset`` TO 'serviceAccount:service-PROJECT_NUMBER@gcp-sa-financialservices.iam.gserviceaccount.com'"

在 Google Cloud 控制台中分析单个结构化问题

  1. 在 Google Cloud 控制台中打开 BigQuery。

    前往 Google Cloud 控制台

  2. 在详细信息窗格中，点击未命名查询标签页以查看编辑器。

  3. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_input_dataset.transaction`
WHERE account_id = '1E60OAUNKP84WDKB' AND DATE_TRUNC(book_time, MONTH) = "2022-08-01"
ORDER by book_time

    此语句会检查账号 ID 1E60OAUNKP84WDKB 在 2022 年 8 月的状态。此账号已与相关方 ID EGS4NJD38JZ8NTL8 相关联。您可以使用 AccountPartyLink 表查找给定账号 ID 的相关方 ID。

    交易数据显示，在有大额现金存款后，针对单个账号进行频繁的往返交易，这看起来很可疑。这些交易可能表明存在欺诈行为（即将一笔大额资金交易拆分为金额较小的多笔交易）或结构化交易。

    单个相关方的可疑交易数据。

  4. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_input_dataset.risk_case_event`
WHERE party_id = 'EGS4NJD38JZ8NTL8'

    此声明表明，存在导致此方退出的情况。风险支持请求是在可疑活动发生两个月后开始的。

    单个相关方的风险信号事件。

  5. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_output_dataset.my_prediction_results`
WHERE party_id = 'EGS4NJD38JZ8NTL8'
ORDER BY risk_period_end_time

    查看预测结果后，您会发现该方在出现可疑活动后的几个月内，风险信号从几乎为零（请注意指数值）跃升至较高值。您的结果可能与所示结果不同。

    单个方的风险评分增加。

    风险评分不是概率。风险评分应始终与其他风险评分相对评估。例如，如果其他风险信号较低，一个看似较小的值也可以被视为正例。

  6. 将以下 SQL 语句复制到编辑器中，然后点击运行。

    SELECT *
FROM `PROJECT_ID.my_bq_output_dataset.my_prediction_results_explainability`
WHERE party_id = 'EGS4NJD38JZ8NTL8'
AND risk_period_end_time = '2022-10-01'

    通过查看可解释性结果，您可以看到正确的特征族得分最高。

    预测的可解释性结果。
