Counterfactual Memorization in Language Models: Distinguishing Rare from Common Memorization

A team from Google Research, University of Pennsylvania and Cornell University proposes a principled perspective to filter out common memorization for LMs, introducing "counterfactual memorization" to measure the expected change in a model’s prediction and distinguish “rare” (episodic) memorization from “common” (semantic) memorization in neural LMs.
