I recently did some analysis on how different style prompts like "be succinct" and "avoid mannered prose" affect LLM outputs and I also saw a ~circular relationship with a 2d dimensional reduction (MDS) of the similarity matrix. I wonder if it's some artifact of PCA/MDS + Gemma's output dist

Glad you got something out of it! Yes, it's hard to tell when something should be in claude.md or added to each subsequent prompt in a session. I need to do a similar analysis here for multi-turn settings and especially coding settings.

Sure! Roughly we are using hierarchical models for reads on underlying count or prevalence data. We use those higher-order means or other fit params to kick off remediation tasks at different levels of that hierarchy depending on those higher level params. We assume some correlation between sibling nodes in that hierarchy.
Question: Can one or another of those thresholds in sibling or parent nodes ever be met if some number of the samples are below some floor reading? Or, how many zeros does it take to silence a threshold check on the node itself, a sibling, or a parent?
To make this tractable I have tried gridding fit parameters, freezing randomness, and using simplified algs like original Metropolis-Hastings

I love z3. I used it for the first time for Jane Street's puzzle last year involving a hashing alg disguised as a neural network. I use a lot of MCMC at work and I have made a few small investigations into MCMC model formal verification via z3, but nothing real yet. This has inspired me to pick that back up.

I do this with claude frequently. The best tactic I have found is to include a finished file as a "style guide" alongside your content prompt.
To find an appropriate style guide for your subject matter, find paper on the arxiv that covers similar material and click the "TeX Source" link.

I like the idea. About question 2, I think you need some way to publicly benchmark your stripped-down models' performance. Your models probably won't be able to perform on the standard benchmarks, but the big models will probably be able to work on your custom eval sets, such as those Hindi math problems.
I would publish: 1) your domain specific eval set 2) your model's results on that eval set 3) biglab's model's results on that eval set
That would give users a way to determine if your model is actually capable in that reduced domain
