thank you very much @brev
Can you show me how to get the document they show in that video clip. I search on internet but haven’t found yet.
Thank in advance.
about this [https://hopding.com/sdr-classifier](https://hopding.com/sdr-classifier) is a very good document but it just explain about mapping from SDR to bucket ( + probabilty distribution) not explain about prediction in t+1, +3, +5…

The SDR Classifer don’t. You use the Temporal Memory to generate prediction of t+1 then use SDR Classier to convert SDR back into processable data.
