I would appreciate recommendations for a preprint server to submit preprints in computational intelligence / computational cognitive science.

I know about the following preprint servers and would appreciate opinions about their relative merits for that topic area, and links to any other relevant preprint servers.

* techrxiv.org/

* preprints.org/

* arxiv.org/
- The available fine-grained categories in Computer Science *might* not cover my topics (depending on how strictly the categories are interpreted).
- The submission formats *might* be incompatible with my writing workflow.

* osf.io/preprints/discover
- OSF Preprints is a network of community-run OSF-hosted preprint servers. The only vaguely relevant community server is PssyArXiv, and it isn't clear that my topics of interest are on-scope for PsyArXiv.

* zenodo.org/
- Appears to have no constraints on format or topic (which is probably positive for me).
- Is not indexed by Google Scholar. (I have views about Google. However, not being indexed by Google means that preprints on Zenodo are effectively invisible to many researchers.)

I recently read @djnavarro 's 2021 paper "If Mathematical Psychology Did Not Exist We Might Need to Invent It: A Comment on Theory Building in Psychology" (doi.org/10.1177/17456916209747).

It's a gem on the role and use of theory in cognitive psychology (and related fields, by extension) and the relation of theory to statistics. As expected, the footnotes are a joy. For my extra reading pleasure, I imagined the paper written in Danielle's sweary-blog style.

The next VSAonline webinar is at 17:00 UTC (not the usual time), Monday 27 January.

Zoom: ltu-se.zoom.us/j/65564790287

Speaker: Anthony Thomas from UC Davis, USA

Title: ”Sketching a Picture of Vector Symbolic Architectures”

Abstract : Sketching algorithms are a broad area of research in theoretical computer science and numerical analysis that aim to distil data into a simple summary, called a "sketch," that retains some essential notion of structure while being much more efficient to store, query, and transmit.

Vector-symbolic architectures (VSAs) are an approach to computing on data represented using random vectors, and provide an elegant conceptual framework for realizing a wide variety of data structures and algorithms in a way that lends itself to implementation in highly-parallel and energy-efficient computer hardware.

Sketching algorithms and VSA have a substantial degree of consonance in their methods, motivations, and applications. In this tutorial style talk, I will discuss some of the connections between these two fields, focusing, in particular, on the connections between VSA and tensor-sketches, a family of sketching algorithms concerned with the setting in which the data being sketched can be decomposed into Kronecker (tensor) products between more primitive objects. This is exactly the situation of interest in VSA and the two fields have arrived at strikingly similar solutions to this problem.

The schedule for the next VSAonline webinar series (January to June 2025) is published at:

sites.google.com/view/hdvsaonl

There are 11 talks around #VectorSymbolicArchitecture / #HyperdimensionalComputing

The talks are (almost always) recorded and published online, in case you can't participate in the live session.

@cian
If (a big if) we performed generalisation at retrieval (rather than at storage, as in almost all current artificial neural networks) then the episodic memories would be the essential input to the generalisation (and inference) process. You are best placed to know what dimensions to abstract over when you have a specific current task and goal to drive generalisation and inference.

(Of course, having arrived at some specific generalisation from the current retrieval, that generalisation might be stored as part of the current episodic memory and be available to guide future generalisations on retrieval.)

What are the implications if episodic memory is the primary form of memory and other (declarative/procedural/etc) memories are epiphenomena arising out of the episodic memories?

Maths/CogSci/MathPsych lazyweb: Are there any algebras in which you have subtraction but don't have negative values? Pointers appreciated. I am hoping that the abstract maths might shed some light on a problem in cognitive modelling.

The context is that I am interested in formal models of cognitive representations and I want to represent things (e.g. cats), don't believe that we should be able to represent negated things (i.e. I don't think it should be able to represent anti-cats), but it makes sense to subtract representations (e.g. remove the representation of a cat from the representation of a cat and a dog, leaving only the representation of the dog).

This *might* also be related to non-negative factorisation: (en.wikipedia.org/wiki/Non-nega) in that we want to represent a situation in terms of parts and don't allow anti-parts.

Most of the Artificial Neural Net simulation research I have seen (say, at venues like NeurIPS) seems to take a *very* simple conceptual approach to analysis of simulation results - just treat everything as independent observations with fixed effects conditions, when it might be better conceptualised as random effects and repeated measures. Do other people think this? Does anyone have views on whether it would be worthwhile doing more complex analyses and whether the typical publication venues would accept those more complex analyses? Are there any guides to appropriate analyses for simulation results, e.g what to do with the results coming from multi-fold cross-validation (I presume the results are not independent across folds because they share cases).

Here is a new version of our tutorial on fitting joint models of M/EEG and behavior! This version is much improved to the previous one due to a ton of additional work by co-author Kianté Fernandez as well as helpful reviewer comments.

Thanks @hosford42 for reminding me of this half-day tutorial on Vector Symbolic Architectures / Hyperdimensional Computing. The authors have been applying HDC/VSA to place recognition in robotics, but the tutorial coverage is much wider.

Hi maths-adjacent peeps, I have a maths notation question: Is there some conventional(ish) symbol for factorisation interpreted as a unary operator - e.g. F where F(x) returns a set of factors of x (but less dull and bland than F).

A quick, inept, internet search didn't find anything. I suspect there isn't a standard, conventional notation. I'm just looking for something I can use in a diagram that would look intuitively plausible as a symbol for factorisation.

@rhgrouls @djnavarro I’m rooting for you to join #julialang universe 😁

The data science ecosystem in Julia is pretty mature but there are hardly any packages in #MathPsych or #Psychometrics. But that’s also an opportunity for you to build them! 🤓 Plus, you are an influencer in the statistical modeling and cog sci field. So a lot of people are also gonna follow what you do with your next step. So Julia please 😬😬
