Suggested Recipes
When you create a new datasource in Amazon ML and statistics are computed for that datasource, Amazon ML will also create a suggested recipe that can be used to create a new ML model from the datasource. The suggested datasource is based on the data and target attribute present in the data, and provides a useful starting point for creating and fine-tuning your ML models.
To use the suggested recipe on the Amazon ML console, choose Datasource or Datasource and ML model from the Create new drop down list. For ML model settings, you will have a choice of Default or Custom Training and Evaluation settings in the ML Model Settings step of the Create ML Model wizard. If you pick the Default option, Amazon ML will automatically use the suggested recipe. If you pick the Custom option, the recipe editor in the next step will display the suggested recipe, and you will be able to verify or modify it as needed.
Note
Amazon ML allows you to create a datasource and then immediately use it to create an ML model, before statistics computation is completed. In this case, you will not be able to see the suggested recipe in the Custom option, but you will still be able to proceed past that step and have Amazon ML use the default recipe for model training.
To use the suggested recipe with the Amazon ML API, you can pass an empty string in both Recipe and RecipeUri API parameters. It is not possible to retrieve the suggested recipe using the Amazon ML API.
