🚨

Local dependence → manifold hypothesis

Distant independence → Markov random fields

New preprint: the latter works in conjunction first, massivly improves data efficiency, and can be exploited by DNNs https://t.co/OjSqzT6bvc

NeurIPS preprint: https://t.co/VZ3r992sxo

Standard models for spatial, sequential, hierarchal, etc data result in drastically reduced effective dimension for density estimation. This effective dimension is orthogonal to other approaches such as sparsity or manifold hypothesis.

Just noticed that Tsybakov (author of one of my favorite textbooks: Intro. to Nonparametric Estimation) wrote a nice extension of my 2021 NeurIPS paper "Beyond Smoothness: Incorporating Low-Rank Analysis into Nonparametric Density Estimation."
Exciting!

OKO got accepted to #ICLR2024🎉🥳 OKO is very simple to use: Just change your sampling from single data point sampling to set sampling and compute cross-entropy for the sum of set data point logits rather than for single data point logits. You will get much better calibration! 🔥

@vivekt17 @aus_hater @whstancil @kpanyc People should really source claims on Twitter. Would fix a lot of problems.

@pronounced_kyle I bought a pack of four of these books for my son. It’s a cute idea but in all honesty, they are not very good, even for babies.

@oneunderscore__ Is this real?

It seems like all math tests for LLMs involve just the direct application of various rules, like a bunch of trig or calc rules, to solve the problem. How about getting a LLM to prove the intermediate value theorem or some other proof that requires a clever construction?

[Robert A. Vandermeulen @robvdm]

@s_mandt I’m not familiar with this. Is this for PhD or masters admissions? How common is it?

[Robert A. Vandermeulen @robvdm]

@MaxPaxCat @broncoslyfer @whstancil Trump refused to turn them over though.
