Researchers have developed GRAB, a novel pipeline designed to enhance multi-table question answering capabilities for large language models (LLMs). This method converts relational data into a heterogeneous graph, encodes it using message passing, and then transfers these signals to a frozen LLM via query-conditioned latent tokens. The GRAB pipeline, with its lightweight 91 million parameter encoder and latent bridge, trains efficiently and significantly boosts performance, particularly in complex multi-table question answering scenarios.
