HTM vs. ARIMA

[kaustabpal]

Can anyone please let me know if the HTM prediction model follows the ARIMA prediction model?
If not, how are they different?

@subutai did a study a long time ago when we called it “CLA”. See here:

They are completely different. A description of HTM (with a short ARIMA comparison) is here:

Continuous Online Sequence Learning with an Unsupervised Neural Network Model

A paper directly comparing the two on a bunch of datasets is here (I don’t know the author):

@subutai

They are completely different

Can you please elaborate in what sense they are completely different?
I am still in learning phase so all these will be really helpful. Thank you.

Well one is completely biologically derived. The other is basically just a math function. I think you’ll need to investigate yourself about what ARIMA is. Share your comparison with us afterwards if you come up with anything interesting?
