Aspects of human memory and Large Language Models

Large Language Models (LLMs) are huge artificial neural networks which primarily serve to generate text, but also provide a very sophisticated probabilistic model of language use. Since generating a semantically consistent text requires a form of effective memory, we investigate the memory properties of LLMs and find surprising similarities with key characteristics of human memory. This result strongly suggests that the biological features of human memory leave an imprint on the way that we structure our textual narratives.
