Researchers have proposed a new theory of how transformer language models memorize factual information, suggesting a 'geometric' form of memorization rather than traditional associative memory. This model posits that learned embeddings encode relational structure, with the MLP acting as a relation-conditioned selector. Experiments with a single-layer transformer demonstrated that logarithmic embedding dimensions suffice for memorizing random bijections, and the MLP learned a generic selection mechanism transferable to new facts.
