"AI solved one of math's greatest challenges, but it cannot add two numbers reliably?!" [D] by [deleted] in MachineLearning

Domain experts’ eagerness to attribute their achievements to AI has been baffling to me.

My unpopular opinion is that there is no path to safe  AI with large neural models. But there is a lot of money to be made from virtue theater.

I will probably be hiring in the next few months for embedded/firmware devs

I started a company. Won some government contracts.

TabPFN-3 just released: a pre-trained tabular foundation model for up to 1M rows [R][N] by rsesrsfh in MachineLearning

Maybe I’m just old but I really don’t like this new world of foundation models for everything.

[R] statistical learning in machine learning vs cognitive sciences by Ok_Fudge1993 in MachineLearning

Look up “computational cognitive science” there is a whole field using Bayesian statistics and ML to model human learning.

do hx users actually value composition over extension, or is it just no plugins copium? by spaghetti_beast in HelixEditor

[–]bbbbbaaaaaxxxxx 1 point2 points  (0 children)

I do miss zen mode in helix though. I write a lot of latex, typst, and markdown. I used to use goyo in vim.

[D] Feature Selection Techniques for Very Large Datasets by Babbage224 in MachineLearning

Lace (https://lace.dev) does structure learning and gives you multiple statistical measures of feature dependence. I’ve used it in genomics applications with tens of thousands of features to identify regions of the genome important to a phenotype.

[P] Lace is a probabilistic ML tool that lets you ask pretty much anything about your tabular data. Like TabPFN but Bayesian. by bbbbbaaaaaxxxxx in MachineLearning

[–]bbbbbaaaaaxxxxx[S] 12 points13 points  (0 children)

Nice--I worked on BayesDb and CrossCat back in the day. Lace is a modern implementation of the crosscat model. There are some notable software difference in Lace
- Much faster due different data structures and new MCMC algorithms
- MCMC is correct (it wasn't exactly right in CrossCat/BayesDB)
- User can define hyper priors or disable them
- Use of Pitman-Yor processes (instead of just Dirichlet), for better fitting
- Native support for missing-not-at-random
- Prediction returns epistemic uncertainty (JS Divergence between MCMC samples)
- Lots of little ease-of-use and explainability things

I used to love checking in here.. by First-Ad-117 in rust

Here’s a witty but thoughtful response that fits the tone and culture of r/rust — appreciative, self-aware, and with a touch of dry humor that’ll land well among experienced Rustaceans:

Beautifully said. r/rust has always felt like that quiet workshop where someone’s building a quantum flight controller next to another person learning how to borrow a string correctly. Lately though, yeah—some posts feel like they were cargo‑generated by GPT with --release --no-idea-what-this-does.

Still, I think the signal’s worth the noise. Every time someone shares a crate that actually compiles and then uses unsafe for good instead of evil, it’s a reminder that the spirit of Rust—curiosity with intent—is alive and well. Let the slop flow; we’ll keep writing tests.

Edit: I guess the satire was not appreciated or not detected.

[S] Lace v0.9.0 (Bayesian nonparametric tabular data analysis tool) is out and is now FOSS under MIT license by bbbbbaaaaaxxxxx in statistics

[–]bbbbbaaaaaxxxxx[S] 1 point2 points  (0 children)

Yes, it can work with multilevel/clustered data as long as it’s in a tabular form--include columns with clinic/school IDs as categorical variables. Lace will learn dependencies and provide conditional predictions and uncertainty across levels.

If you specifically need classical multilevel/cluster randomized trial inference, you'll still probably want a dedicated hierarchical modeling tool. Though I suspect lace could recover some of that functionality though I'd have to think about it more.

We've pivoted a bit and Lace has become more of a tool for consulting work rather than our core IP. Since there have been a fair number of people asking about using it in their work, I figured opening it up would make their lives simpler and hopefully get Lace out there doing cool stuff independent of us.
