Conferences; research updates
This week, Nov 17-18, Thu-Fri, 8am-11:45am Boston time, "Quantum physics and the first-person perspective": www.essentiafoundation.org/quantum-physics-and-the-first-person-perspective/seeing/
JuliaCon 2023, juliacon.org/2023/ the call for proposals is posted, deadline Dec 18: pretalx.com/juliacon2023/cfp
I've spent more quality time focusing of two breakthroughs in understanding the nature and the behavior of machine learning models which came from the "penumbra" of "prosaic alignment" start-ups and which I wrote about in my previous two posts.
"Grokking is (more or less) solved." I took brief notes between Oct 21 and Oct 23: github.com/anhinga/2022-notes/tree/main/Grokking-is-solved
"Generative autoregressive models are similators." I took extensive notes between Oct 5 and Oct 23: github.com/anhinga/2022-notes/tree/main/Generative-autoregressive-models-are-similators
I am continuing to develop thoughts related to these topics, I am going to gradually write more about those topics in the comments.

This is Boston campus, where I have friends, and where I've even given couple of talks in 2009 and also attended some talks and interacted with people in more recent years...
This was one of my talks there: "Remarks on Neurodynamics: Spikes, Spike Synchronization, and Spike-Timing-Dependent Plasticity", https://www.cs.brandeis.edu/~bukatin/neuro-talk-mar-25-2009.pdf
And this was another: "Partial Metrics, Fuzzy Equalities, and Metric-Entropy Pairs", https://www.cs.brandeis.edu/~bukatin/partial-metrics-talk-jun-2009.pdf

https://en.wikipedia.org/wiki/SIC-POVM - symmetric, informationally complete, positive operator-valued measure
This is one of papers from that group: "The SIC Question: History and State of Play", https://arxiv.org/abs/1703.07901
The Wikipedia page says:
"A symmetric, informationally complete, positive operator-valued measure (SIC-POVM) is a special case of a generalized measurement on a Hilbert space, used in the field of quantum mechanics. A measurement of the prescribed form satisfies certain defining qualities that makes it an interesting candidate for a "standard quantum measurement", utilized in the study of foundational quantum mechanics, most notably in QBism. Furthermore, it has been shown that applications exist in quantum state tomography and quantum cryptography, and a possible connection has been discovered with Hilbert's twelfth problem."
In particular: "SICs and Algebraic Number Theory", https://arxiv.org/abs/1701.05200

She has a recent joint paper with Rovelli: "Information is Physical: Cross-Perspective Links in Relational Quantum Mechanics", https://arxiv.org/abs/2203.13342
She publishes quite a lot: https://arxiv.org/search/physics?searchtype=author&query=Adlam%2C+E

"quantum gravity (particularly on tensorial group field theories (group field theories, random tensor models), loop quantum gravity, spin foam models, lattice quantum gravity, non-commutative geometry), gravitational physics, fundamental cosmology; wider research activities in philosophy of science and foundations of physical theories, in particular foundations of quantum mechanics and philosophy of spacetime theories"

He proposes to focus on "agents", and he defines agents as entities performing modeling activity (this is, in some sense, in line with my recent thinking).
But he notes that quantum gravity is the real challenge in this sense, and the real litmus test for any methodology...
