Quantifying Point Contributions: A Lightweight Framework for Efficient and Effective Query-Driven Trajectory Simplification

Summary: MLSimp: a mutual-learning, query-driven trajectory simplification framework combining GNN-TS (attention-based GNN capturing globality and uniqueness to avoid iterative pruning) and Diff-TS (diffusion-based signal amplification for low-rate retention). Cuts simplification time 42–70% and improves query accuracy up to 34.6% vs eight baselines. (summarized by gpt-5-mini on Feb 09 2026)
