Researchers have developed ScaleTraj, a new Transformer-based model designed to generate more realistic human trajectories. Existing methods often struggle to balance individual trajectory realism with population-level statistical fidelity, leading to issues like the "Population-Level Displacement Gap." ScaleTraj addresses this by decomposing location prediction into scale selection and scale-aware destination prediction. Experiments show ScaleTraj effectively reduces this gap and improves fidelity compared to existing generators. AI
