Vector Symbolic Architecture (VSA) is the European name. Base is Pentti Kanerva's 1988 book, "Sparse Distributed Memory". Now referred to as "HDC" or "HD". Search Pentti Kanerva now Staff Scientist at UC Berkeley Redwood Center for Theoretical Neuroscience or Mohsen Imani, now UC Irvine former at UC San Diego. Introductory article - "Hyperdimensional computing and its role in AI" by,Givi Odikadze: https://medium.com/…

Thanks for giving the name, it's been bugging me for the past hour at least. I just couldn't get it.

When I read over SDM I got the impression it wasn't terribly useful, if anyone wants to set me right please do.

Bizarro the one on-topic comment here is "Dead." I came across this in reviewing echo state networks which this appears to be a distant relative of. The code samples made it useful.

It might be because of the medium.com link, which is disliked by many for its many accessibility issues.

Have you come across any other interesting resources? I've recently been delving into topics surrounding echo state networks for my thesis, so I'd appreciate any pointers.

The original machine had a base plate of prefabulated amulite, surmounted by a malleable logarithmic casing in such a way that the two main spurving bearings were in a direct line with the panametric fan. The latter consisted simply of six hydrocoptic marzlevanes, so fitted to the ambifacient lunar waneshaft that side fumbling was effectively prevented. The main winding was of the normal lotus-o-deltoid type placed in panendermic semi-boloid slots in the stator, every seventh conductor being connected by a nonreversible tremmie pipe to the differential girdlespring on the "up" end of the grammeters.

This referred to IcePowder's comment, I revived it since the information given in it seems to be accurate as far as I can tell. You can do this yourself by the way: click the time of the post (".. minutes ago" / ".. days ago") to view the comment on its own and click the link to "Vouch" in the top line, where also the name and the time since commenting is shown.

Thanks kindly for that; I didn't know I had this power.

Gotta love those grammeters!

Some of the Italians at University of Pisa seemed to want to understand the echo state property better. Gallicchio and Filippo Maria Bianchi (I assume his student) wrote a couple of interesting papers I haven't totally absorbed yet, probing the critical ridge in various ways.

That said, it's pretty marginal stuff. ESNs are weird. Cool weird anyway.

If I were looking at it in a serious way rather than reading the funny papers, I'd think about ways of applying topological ideas to ESNs. ESNs on the critical ridge probably have an interesting graph when projected onto a topological space.
