Prediction Time Interval and Bitemporal Streams
The previously mentioned time interval for which a temporal attribute has the values is the Prediction Time Interval. It is an additional time interval in the metadata of a stream element next to the normal stream time interval. It needs to be activated in the metadata definition of a query:
| Code Block |
|---|
metaattribute = ['TimeInterval', 'PredictionTimes'], |
As you can see, the metadata is called PredictionTimes. That is because in fact the metadata holds a list of non-overlapping time intervals. That is due to the algebra behind this approach and is explained later on.Text
