CITYREP: A Unified Benchmark for Urban Representations Across Cities, Tasks, and Modalities 事件

CITYREP: A Unified Benchmark for Urban Representations Across Cities, Tasks, and Modalities arXiv:2605.26036v1 Announce Type: new Abstract: Urban representation learning encodes complex urban environments into general-purpose embeddings for diverse downstream tasks and emerging urban foundation models. However, current evaluations are limited, typically focusing on one or two cities and tasks and relying on random splits that introduce spatial leakage, leading to inflated performance and weak s
