LatticeBridge: Rare-Event Sequential Inference for Faithful Structured Sequence Synthesis
Researchers have developed LatticeBridge, a novel method for structured sequence generation that addresses the challenge of satisfying multiple input-derived constraints within a single output. This approach frames the problem as a rare-event sequential inference task, combining a prefix language model with instance-compiled surface automata and a specialized Monte Carlo decoder. LatticeBridge aims to improve the faithfulness of generated sequences by ensuring all required anchors are jointly realized, outperforming baseline methods on benchmarks like CommonGen and WikiBio.
