We show that a simple geometric insight, isotropic Gaussian representations, can fix this. Here's how 👇 2295
Ivan Rubachev @puhsu.bsky.social · 13/02/2026To piggy-back a bit on foundation models for structured data discussion here My colleagues at Yandex Research just updated the GraphPFN paper. It's a Graph Foundation Model that works on graph datasets with tabular features, and shows SOTA results both in ICL regimes and when fine-tuned.arxiv.orgGraphPFN: A Prior-Data Fitted Graph Foundation ModelGraph foundation models face several fundamental challenges including transferability across datasets and data scarcity, which calls into question the very feasibility of graph foundation models.

Supporting Rust's standard library enables existing Rust code to work on the GPU and makes GPU programming feel normal.vectorware.comRust's standard library on the GPUGPU code can now use Rust's standard library. We share the implementation approach and what this unlocks for GPU programming. 424957
