Backtest window - Setting

0

I'm using Forecast from web interface and I can't find a way to set the backtest parameters (which by default is 1, which is quite impractical). I found documentation that would tell me how to do it, but it seems that it is not available in the current version of Forecast. Setting backtest I understand that I could do it by code, but I wanted to see if I could find a way. On the other hand, the current version apparently doesn't let me select the algorithm manually either, is that correct? Thank you!

Hi FlowerCba,

Due to changes in Forecast service, Forecast UI now provides an 'AutoPredictor' which provides the optimal combination of algorithms to each time series in the dataset. We can no longer configure backtesting from the UI. The UI only uses CreateAutoPredictor API [1] which does not include the backtesting options.

As you may already know, you can control the backtesting configuration when creating the predictor via SDK/CLI using CreatePredictor API [2]. This operation creates a legacy predictor that does not include all the predictor functionalities provided by Amazon Forecast.
