Classical billiards can compute. With Isaac Ramos, we show that 2D billiard systems are Turing complete, implying the existence of undecidable trajectories in physically natural models from hard-sphere gases to celestial mechanics. Determinism ≠ predictability. 🎱🧠 @upc.edu @ricardsole.bsky.social

Goal selection through the lens of subjective functions: arxiv.org/abs/2512.15948 I welcome any feedback on these preliminary ideas.

We took a stab at how to infer both the dynamics and control parameters of partially-observable systems. It’s a nasty problem, but @vgeadah.bsky.social made tremendous progress, ending up with some really elegant formalisms.

🚀 Excited to announce that I'm looking for people (PhD/Postdoc) to join my Cognitive Modelling group @uniosnabrueck.bsky.social. If you want to join a genuinely curious, welcoming and inclusive community of Coxis, apply here: tinyurl.com/coxijobs Please RT - deadline is Jan 4‼️

🚨 🆕 Preprint 🚨 How does the brain represent natural images? Using MEG + multivariate analysis, we disentangle contributions of retinotopy, spatial frequency, shape, and texture Together, our results reveal how visual features jointly and dynamically support human object recognition. link 👇

I use EEG/MEG. When I meet like-minded researchers at conferences, the discussion always circles back to one thing: admitting that results may be confounded by leakage (also known as remaining field spread—RFS). In our new preprint, we quantify RFS in parcellated data using cross-talk function—CTF.🧵

Honestly, I couldn't say -- I'm hardly an expert in pre-whitening. Luckily, Mandy Mejia is a co-author on the paper (and also wrote this awesome blogpost, like, 10 years ago). We basically followed her approach as close as possible. mandymejia.wordpress.com/2016/11/06/h...

Institutional autonomy is a major facet of academic freedom. Institutions set academic priorities through internal collegial processes. Starving unis into hiring freezes and then telling them they can only have funds to recruit if they check vapid government PR boxes attacks that autonomy.

If you calculated noise ceilings (NC) based on split-half reliability - e.g. to compare models - this one is important! Seems many published studies miscalculated it, overestimating model performance. First, let's make this crystal clear: NC = 2*r / (1+r) where r is split-half correlation.

New preprint w/ Malin Styrnal & @martinhebart.bsky.social Have you ever computed noise ceilings to understand how well a model performs? We wrote a clarifying note on a subtle and common misapplication that can make models appear quite a lot better than they are. osf.io/preprints/ps...
