thank you @marty1885

I found this https://www.businesswire.com/news/home/20170620005440/en/New-Research-Paper-Numenta-Demonstrates-Results-Machine

This paper show that there are 3 anomalies in detail ( 1 is planned, 2 are outages) and a plot it’s very clear.

All are good for me to check my model.

That you mean i should use OPF for real applications ?

Now i follow algorithm http://nupic.docs.numenta.org/1.0.3/api/algorithms/index.html

I think it 's esier to understand because it follow the HTM theory. After i understand Algorithm, i will move forward to OPF for real applications . Do you think so ? Is it a right approach ?

Thank you very much.
