A new research paper explores the memorization behavior of large language models (LLMs) when applied to generative recommendation systems. The study found that LLMs tend to memorize direct successors of items from training data more than traditional models, with most performance gains attributed to this memorization. To address this, the researchers propose a novel training strategy called IIRG, which teaches LLMs to capture collaborative and semantic item relationships beyond simple one-hop transitions, leading to significant improvements.
