Create and manage backtest results

This page shows you how to create and manage AML AI backtest prediction results. Backtest prediction uses a trained model on existing historical data. For these months, the dataset must contain a label.

The same dataset can be used for training and backtest as long as the training end date is before the backtest dates.

You only need to create the backtest results and export the associated metadata at this point. The other backtest results methods are provided as a convenience.

Before you begin

To get the permissions that you need to create and manage backtest results, ask your administrator to grant you the Financial Services Admin (financialservices.admin) IAM role on your project. For more information about granting roles, see Manage access.

You might also be able to get the required permissions through custom roles or other predefined roles.

Create backtest results

Some API methods return a long-running operation (LRO). These methods are asynchronous. The operation might not be completed when the method returns a response. For these methods, send the request and then check for the result.

Send the request

To create backtest results, use the projects.locations.instances.backtestResults.create method.

Before using any of the request data, make the following replacements:

PROJECT_ID: your Google Cloud project ID listed in the IAM Settings
LOCATION: the location of the instance; use one of the supported regions:
- us-central1
- us-east1
- asia-south1
- europe-west1
- europe-west2
- europe-west4
- northamerica-northeast1
- southamerica-east1
INSTANCE_ID: a user-defined identifier for the instance
BACKTEST_RESULTS_ID: a user-defined identifier for the backtest results
MODEL_ID: a user-defined identifier for the model
BACKTEST_DATASET_ID: the user-defined identifier for the dataset used for the backtest; tables should not have the training label columns
BACKTEST_END_DATE: The latest time from which data is used to generate features for backtests. This date should be the same or earlier than the end time of the datasets. Use RFC3339 UTC "Zulu" format (for example, 2014-10-02T15:01:23Z).
PARTY_INVESTIGATIONS_PER_PERIOD_HINT: A number that gives the tuner a hint on the number of parties from this data that will be investigated per period (monthly). This is used to control how the model is evaluated. For example, when trying AML AI for the first time, we recommend setting this to the number of parties investigated in an average month, based on alerts from your existing automated alerting system.

Request JSON body:

{
    "model": "projects/PROJECT_ID/locations/LOCATION/instances/INSTANCE_ID/models/MODEL_ID",
    "dataset": "projects/PROJECT_ID/locations/LOCATION/instances/INSTANCE_ID/datasets/BACKTEST_DATASET_ID",

    "backtestPeriods": 5,
    "performanceTarget": {
      "partyInvestigationsPerPeriodHint": "PARTY_INVESTIGATIONS_PER_PERIOD_HINT"
    }
}

To send your request, choose one of these options:

curl

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login , or by using Cloud Shell, which automatically logs you into the gcloud CLI . You can check the currently active account by running gcloud auth list.

Save the request body in a file named request.json. Run the following command in the terminal to create or overwrite this file in the current directory:

cat > request.json << 'EOF'
{
    "model": "projects/PROJECT_ID/locations/LOCATION/instances/INSTANCE_ID/models/MODEL_ID",
    "dataset": "projects/PROJECT_ID/locations/LOCATION/instances/INSTANCE_ID/datasets/BACKTEST_DATASET_ID",
    "endTime": "BACKTEST_END_DATE",
    "backtestPeriods": 5,
    "performanceTarget": {
      "partyInvestigationsPerPeriodHint": "PARTY_INVESTIGATIONS_PER_PERIOD_HINT"
    }
}
EOF

Then execute the following command to send your REST request:

curl -X POST \
     -H "Authorization: Bearer $(gcloud auth print-access-token)" \
     -H "Content-Type: application/json; charset=utf-8" \
     -d @request.json \
     "https://financialservices.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/instances/INSTANCE_ID/backtestResults?backtest_result_id=BACKTEST_RESULTS_ID"

PowerShell

Note: The following command assumes that you have logged in to the gcloud CLI with your user account by running gcloud init or gcloud auth login . You can check the currently active account by running gcloud auth list.
