We will use Boto3 and Python SDK and follow the same method of generating the parameters for datasources that we used in Chapter 7, Command Line and SDK, to do the Monte Carlo validation: we will generate features corresponding to power 2 of x to power P of x and run N Monte Carlo cross-validation. The pseudo-code is as follows:

for each power from 2 to P:
    write sql that extracts power 1 to P from the nonlinear table
    do N times
        Create training and evaluation datasource
        Create model
        Evaluate model
        Get evaluation result
        Delete datasource and model
    Average results

In this exercise, we will go from 2 to 5 powers of x and do 5 trials for each model. The Python code to create a datasource from Redshift using create_data_source_from_rds() is as follows:

response = client.create_data_source_from_redshift(
    DataSourceId...
