How Amazon Forecast Works

When creating forecasting projects in Amazon Forecast, you work with the following resources:

  • Datasets and Dataset Groups – You create an Amazon Forecast dataset and import your training data. You create a dataset group and add related datasets. Amazon Forecast algorithms use your datasets to train custom forecasting models, called predictors.

  • Predictors – Predictors are custom models trained on your data. You can train a predictor by choosing a prebuilt algorithm (which includes the data featurization associated with the algorithm) or, by choosing the AutoML option, ask Amazon Forecast to pick the best algorithm for you.

  • Forecasts – You can generate forecasts for your time-series data and export the forecasts to your own Amazon Simple Storage Service (Amazon S3) bucket.
