Universal Spin Models are Universal Approximators in Machine Learning
The two notions of universality turn out to be very similar. arXiv: 2507.07669. Tobi Reinhart and Gemma De les Coves
Mechanistic and emergent universality in natural languages
We examine notions of universality and recursion in grammars, writing systems and the occurence of words, and find that they come in two main flavours: mechanistic and emergent. Preprints:202402.1330
A framework for universality in physics, computer science and beyond
What do universal Turing machines, universal spin models, NP completeness, top of a preorder and denseness of a subset have in common? They are all universal in a certain (precise) sense.
