General

Q: What is Amazon Forecast?

Amazon Forecast is a fully managed service that uses machine learning to deliver highly accurate forecasts.

Based on the same technology used at Amazon.com, Amazon Forecast uses machine learning to combine time series data with additional variables to build forecasts. Amazon Forecast requires no machine learning experience to get started. You only need to provide historical data, plus any additional data that you believe may impact your forecasts. For example, the demand for a particular color of a shirt may change with the seasons and store location. This complex relationship is hard to determine on its own, but machine learning is ideally suited to recognize it. Once you provide your data, Amazon Forecast will automatically examine it, identify what is meaningful, and produce a forecasting model capable of making predictions that are up to 50% more accurate than looking at time series data alone.

Amazon Forecast is a fully managed service, so there are no servers to provision, and no machine learning models to build, train, or deploy. You pay only for what you use, and there are no minimum fees and no upfront commitments.

Q: How do I get started with Amazon Forecast?

You can get started with Amazon Forecast using an API or AWS Console. The first step is to upload your data into Amazon Forecast. Once data is uploaded, you can have Amazon Forecast automatically try all different algorithms to train multiple models, then provide the model with the highest forecasting accuracy. You can also manually choose one of the forecasting algorithms to train a model. Once you have the model, Amazon Forecast provides comprehensive accuracy metrics to evaluate the performance of the model. If you are satisfied, you can deploy the model within Amazon Forecast to generate forecasts with a single click or API call. Amazon Forecasts can be retrieved via API, exported in CSV format, or visualized in the console.

Q: What data does Amazon Forecast require to start forecasting?

Amazon Forecast can provide a forecast given any historical set of time series data. However, customers can also provide meta-data available for each of the time series (e.g., the location of a house when predicting energy consumption) as well as other related time series data (e.g., historical pricing data along with sales data for products).
