Has anyone seen this paper before?
The authors would like to thank both Subutai Ahmed and Yuwei Cao from Numenta for their valuable insights and members of the NanoComputing Research Lab for the rigorous technical discussions on the SP.
Seems like there was a collaboration.
Yes, we've met at a couple of conferences and spoken to them about the SP and TM but there's no specific collaboration (i.e. we weren't involved directly in this paper - it's their original work).
I've seen a lot of mentions of this paper on Twitter recently.
