The ideal aggregation window is one that allows you to aggregate as much as you can but not too much. There is no one-size-fits-all value, as aggregation is application-dependent. HTM Studio makes a good first guess with any data set, but getting the best aggregation possible requires knowledge about the application itself. HTM Studio defaults to an automated technique that determines a best-effort aggregation window for your data. However, you can change the value of the aggregation window (or choose to not aggregate the data at all) in “advanced settings” when you create a new model.
