09:09 < lsneff> Is there a way to distill concepts into a single identifier that is common to all ways to representing that concept? Something kinda like word2vec?
09:10 < lsneff> I guess this is a pretty key part of ai research.
09:18 < L29Ah> afaik it's always ad-hoc
09:20 < L29Ah> say in nlp you have words cut of their insignificant morphemes and numbered
09:49 < lsneff> Okay
09:50 < lsneff> I guess I'll probably have to wait for a bit longer, but the reason why I asked the question was that I'm trying to figure out if it's possible to write a browser extension that will surface a digital "sticky note" when you come across the same idea as what you originally put the note on.

12:22 < kanzure> lsneff: maybe a bloom filter of some kind
12:25 < kanzure> "My most plausible scenario for the Singularity now is someone figuring out how to augment short term memory with implants. I think we are going to find that attention is dominated by working set memory, and people who can juggle even twice as much stuff are going to operate fundamentally differently than those who can’t afford or won’t have the surgery. And past 5x it may become ...
12:25 < kanzure> ...difficult to even communicate, much less compete."
12:26 < kanzure> from https://news.ycombinator.com/item?id=24391686
12:30 < lsneff> Interested idea kanzure, I'll think about whether a bloom filter would work.
12:30 < lsneff> Also, I'm in dire need of that implant, my working memory is tragically brief.
12:44 < lsneff> Actually, upon further analysis, I'd say my visual working memory is good. I underuse it however, since many things don't immediately fit into that paradigm

13:32 < TMA> I had a better working memory when I was younger
13:32 < TMA> do we even know, where is the working memory located in the brain?

13:50 < fenn> thalamus
13:52 < fenn> here's a schematic you can try to make sense of http://web.mit.edu/amarbles/www/docs/thalamic-relay.png
13:53 < kanzure> https://diyhpl.us/~bryan/papers2/neuro/cognitiveconsilience/stitched-diagram.jpg
13:54 < fenn> kanzure i have had trouble communicating with steve in part because he has more working memory
13:54 < kanzure> yep...
13:54 < fenn> often i'll ask him to just literally repeat exactly what he said
13:55 < kanzure> try that with other people, it's really interesting how many will say "i have no idea what i just said"
13:56 < L29Ah> i frequently do
13:56 < L29Ah> 23:50:39]<fenn> thalamus
13:56 < L29Ah> interestingly, https://en.wikipedia.org/wiki/Thalamus has 0 entries of "working memory"
13:57 < fenn> i could be wrong
13:57 < kanzure> ask superkuh
13:58 < fenn> neuroanatomy is such a pain in the ass of overlapping maps that i never seriously tried learning it
13:58  * L29Ah subscribes to the hypothesis that working memory is a transient activation pattern of multiple parts of brain, depending on modality
13:59 < fenn> the thalamus has tentacles that extend out into other regions of the brain and can activate them or retrieve information from them and store it locally
13:59 < lsneff> An amazing part of technology is that it's a leveler. Assuming this implant eventually exists, it'd put people with naturally excellent working memory on the same level as those without good working memory.
14:00 < fenn> maybe
14:00 < fenn> there are many assortative mating behaviors that depend on fluency with words and concepts, e.g. humor
14:01 < superkuh> I'd say that awareness of working memory certainly requires ~40 hz active thalamocortical loops but working memory itself probably varies per sense.
14:01 < fenn> the implant functionality may not extend to all cognitive realms, or be easily detectable as an implant-assisted thought
14:18 < kanzure> 13:58  * L29Ah subscribes to the hypothesis that working memory is a transient activation pattern of multiple parts of brain, depending on modality
14:18 < kanzure>  "Oh, how convenient! A theory about God that doesn't require looking through a telescope!"
14:19 < kanzure> https://comb.io/34SmVE
14:20 < kanzure> "transient ativation pattern" is just vague enough to not be actionable
14:24 < L29Ah> kanzure: a theory doesn't need to be "actionable" to be scientific, and afair the research supports the hypothesis
14:33 < kanzure> falsifiability?
14:35 < L29Ah> it is falsifiable
