Reposted by Antoine BosselutTiago Pimentel @tpimentel.bsky.social · 01/10/2025Very happy this paper got accepted to NeurIPS 2025 as a Spotlight! 😁 Main takeaway: In mechanistic interpretability, we need assumptions about how DNNs encode concepts in their representations (eg, the linear representation hypothesis). Without them, we can claim any DNN implements any algorithm! 0254
