:* [[File:Symbol possible vote.svg|16px]] The article in currently ineligible for DYK, because it is so poorly written. The article apparently deals with a particularly [[content-addressable memory]] structure that is used as a model for long-term memory, especially for human semantic-memory. Its first "section" contains exactly one sentence: "The general formula is <math>2^n</math> where ''n'' is the number of dimensions of the space, and <math>2^n</math> is the number of feasible memory items", which tells little to the reader. In the example, I suspect that each sentence should be parsed for semantic information, so that some relation between this "formula" and the "example" be suggested.
The lede confuses the model and the modelled. There are typographical errors with spacing. The split infinitive should be avoided in the DYK blurb. The article seems very short 2000 characters, which is only 500 over the minimum size. The formatting of the sources often has just a title linked to a technical report, without mentioning that the working paper was published in a conference proceedings; use Google Scholar for publication data. <small><span style="border:1px solid black;padding:1px;">[[User:Kiefer.Wolfowitz|<font style="color:blue;background:yellow;">&nbsp;'''Kiefer'''</font>]].[[User talk:Kiefer.Wolfowitz#top|Wolfowitz]]</span></small> 09:38, 6 November 2011 (UTC)
 
:*''Comment:'' The nominator has expanded the article a few days after these comments were made but did not leave any comment here. To be honest, I do not believe the article in its current state is ready for Wikipedia, let alone the main page. It omits core parts of the explanation, e.g. why so many dimensions are useful, and it confuses the matter to an extent that, even with a bit of background in mathematics, it becomes totally incomprehensible. For instance, the aim is to retrieve about 1000 bits of information, not 2^1000. We cannot store the latter amount for quite a few <s>years</s> millennia to come, and we will therefore not very soon need an algorithm to retrieve it. 2^1000 is ''a lot'', see [[Wheat and chessboard problem|chessboard paradox]]. I thought of a hoax, but Kanerva's paper has over 600 citations. Suggest to '''close''' this nomination as unsuccessful. --[[User:Pgallert|Pgallert]] ([[User talk:Pgallert|talk]]) 20:35, 6 December 2011 (UTC){{#if:no|</div></noinclude>|{{#ifeq:{{FULLPAGENAME}}|Template talk:Did you know/{{SUBPAGENAME}}|[[Category:Pending DYK nominations]]|{{#ifeq:{{FULLPAGENAME}}|Template:Did you know nominations/{{SUBPAGENAME}}|[[Category:Pending DYK nominations]]}}}}}}<!--Please do not write below this line or remove this line.

Hello, dear friend! My name is Izetta. I smile that I can unify to the whole world. I live in Great Britain, in the region. I dream to head to the different countries, to get acquainted with intriguing people.
