New Approach to Block-Sparse Featurizers
burny_tech · x · 2026-07-09
A post shares a research update from Goodfire proposing Block-Sparse Featurizers (BSFs), which discover concepts in model activations using multi-dimensional "blocks" rather than individual directions. The forwarded content also mentions that their AI neuroscientist, "silico," can automatically train BSFs for in-progress or open-source models, with early access now available.
