Researchers have developed a new method called AdaPop (Adaptive Popularity) to improve the unlearning process in large language models (LLMs). Unlike existing methods that apply uniform pressure to remove data, AdaPop considers the popularity of facts within the training data. It uses a combination of local token confidence and a popularity-dependent exponent, derived from external sources like Wikidata or LLM-as-a-Judge, to balance forgetting and retaining information. Experiments show AdaPop leaks significantly less forgotten content compared to competing methods, while internal metrics indicate that forgotten data representations move further from the original model's states, and retained data representations stay closer.
