Getting Started

First, you must create a dataset group and import your historical data into Amazon Forecast. You can use the AWS console, the AWS CLI, or the AWS SDKs. You can also use built-in data connectors to import data from Amazon S3, Amazon Redshift, or Amazon Athena. Your data should include a timestamp column, a target value column, and any other relevant features that can influence your forecasts.

You can also choose from a list of predefined algorithms or provide your custom algorithm. You can also specify how far ahead you want to forecast and how often you want to generate forecasts.

Finally, you need to create a forecast and query the results. You can use the AWS console, the AWS CLI, or the AWS SDKs. You can also use the Amazon Forecast Query API to programmatically access your forecasts. You can view various metrics and visualizations to evaluate the accuracy and quality of your forecasts. You can also export your forecasts to Amazon S3 or consume them in other AWS services.
