to appear at #alt.vis 2025: THEORY IS SHAPES

sure "theory figures" are great, but @matthew.wiki, @maryamhed.bsky.social, me, and Carolina Nobre wonder: why always a 2D plane or a flowchart? why not icebergs, horseshoes, Möbius strips, or BLT sandwiches?

Abstract and teaser figure of the paper "Theory is Shapes" by Matthew Varona, Maryam Hedayati, Matthew Kay, and Carolina Nobre.

The teaser figure is an "iceberg" theory figure, showing four levels: the tip of the iceberg, containing a nested set diagram and a Cartesian plane. The next level down (just under the water) has a complicated flow charts and a combination flow chart and matrix. The next level down has the iceberg figure itself and a horseshoe. The final level contains a Möbius strip and a BLT sandwich.

The abstract reads:

"Theory figures" are a staple of theoretical visualization research. Common shapes such as Cartesian planes and flowcharts can be used not only to explain conceptual contributions, but to think through and refine the contribution itself. Yet, theory figures tend to be limited to a set of standard shapes, limiting the creative and expressive potential of visualization theory. In this work, we explore how the shapes used in theory figures afford different understandings and explanations of their underlying phenomena. We speculate on the value of visualizing theories using more expressive configurations, such as icebergs, horseshoes, Möbius strips, and BLT sandwiches. By reflecting on figure-making's generative role in the practice of theorizing, we conclude that theory is, in fact, shapes.

The only thing that makes this slow is not being in parallel. The "R doesn't work with for loops" has become practically a superstition. Yes, vectorised operations are much better in R than loops, but plenty of operations (like this modelling) don't lend themselves to vectorisation.

It's a cognitive dissonance thing for me

On one hand, I hate how the server knows perfectly well that I have access because who else will want a math stat paper from 1973 but I still have to do the whole login dance

On the other hand, I remember having to walk across campus to photocopy the paper

My goto (depending on the size of amzn) has been to expand.grid p, d, & q and do some kind of apply function that can be run in parallel if needed. Admittedly that is when the component pdqs are in the hundreds or thousands.

The plot sounds fun! Thanks for the recommendation!

lol, I was toying with gemini to explain a bunch of LLM transformer background knowledge to me since it's way out of my self study depth and for no good reason at all it pulls a diagram of a literal electronics transformer at the end

screenshot showing a large image showing of an electronics transformer works including two wire loops, transformer core, AC power on a primary circuit and lightbulb on the primary circuit, with variables for power and voltage turns, cretited to getty images. Immediately above in text are mathematical formulae and a discussion of the billions of parameters in an LLM transformer model

Perhaps that’s why the R Gods kept this syntax a secret: to protect us from ourselves 👀

That’s what I love about R: It gives you infinite possibilities to shoot yourself in the foot!

One of my top five favorite #rstats blogs www.quantumjitter.com just published a new entry after almost a year of silence.

He does a really great job of authoring analysis with clear and clean code.

I've enjoyed his posting a lot and suggest you check him out!

I guess the government calling a British trade mission to India the “largest-ever *government* trade mission to India” is honest, if in a slightly tortured way.

In a new paper, we provide fresh evidence on the macroeconomic effects of public investment in 27 EU member states. We find that public investment has favorable effects on output and unemployment; doesn't crowd out private investment; and doesn't jeopardise debt sustainability.
