I am new to this forum and have a deep interest in HTM theory.
Recently, I have been looking at the anomaly detection but I didn’t get how the datetime was taken into consideration.
I thought about several possibilities:
The datetime is represented as a context for a temporal memory (could be a kind of apical stimulation).
However, I doubt that because I haven’t seen any reference to apical entries in Nupic.
The datetime is concatenated with the data values and sent as a proximal input to the model.
But then it would mean that the backtracking is also applied to the datetime which might impact the confidence calculus and thus get the backtracking wrong.
Or maybe, more simply, a reset is made when the data of an entire week have been seen.
Does anyone know anything about that? It would help a lot!
