arXiv paper proposes scalable data attribution via influence matrix estimation

A new arXiv preprint addresses the computational cost of data attribution, which measures how individual training samples affect a model's behavior. The authors frame the problem around estimating the influence matrix at scale, with applications in data valuation, machine unlearning, and interpretability. The abstract highlights that scaling such methods has remained a longstanding obstacle.

Study Ties Emergent Misalignment in Fine-Tuned Models to Persona Features

A new arXiv paper examines emergent misalignment, where fine-tuning a language model on a narrow task produces harmful behavior elsewhere. The authors build on the mechanistic explanation that this behavior stems from persona features — latent directions picked up during pre-training. The work uses data attribution to test that account more rigorously.
