Amazon Forecast


Amazon Forecast uses historical time series data combined with user provided parameter data to generate predictions. The service requires time series data as an input. This can be argumented with local weather data. The desired quantile or mean forcast can be selected and the forcast is output as a CSV file. The output is accompanied by a explainability report for explaining driving factors such as price or weather. The service automatically trains and deploys the model. It also tests the model to track it’s accuracy over time to identify re-training needs using a technique called backtesting. Backtesting involves comparing the models future prediction against the actual outcome.

Amazon Forecast allows forecasting to be performed without having to set up AWS infrastructue an train a model. This is termed as AWS doing the heavy lifting. However if more control over the model is required the Sagemaker built in algorithms can be used, particularly the Deep AR Forcasting algorithm.
