Investigating Representation Universality: Case Study on Genealogical Representations

Kavli Affiliate: Max Tegmark | Summary:Motivated by interpretability and reliability, we investigate whether large language models (LLMs) deploy universal geometric structures to encode discrete, graph-structured knowledge. To this end, we present two complementary experimental evidence that might support universality of graph representations. First, on an in-context genealogy Q&A task, we train a cone probe to […]
