英文摘要Urban representation learning leverages heterogeneous data. While unified frameworks that combine feature fusion and contrastive learning have achieved promising results, two key challenges remain: 1) the lack of structural awareness often leads to suboptimal negative sampling and reduces the discriminability of embeddings; and 2) the inherently conflicting optimization objectives between fusion and contrastive modules may result in unstable training and suboptimal convergence. To address these issues, we propose SAMC, a Structure-Aware Multi-view representation learning framework with Coordinated fusion and alignment. SAMC introduces a multi-view contrastive learning module that incorporates structural similarity into negative sampling, thereby enhancing semantic coherence and cross-view consistency. To improve training stability, a flexible optimization strategy that incorporates soft Lagrangian constraints and stepwise state tracking is designed to coordinate gradient updates across fusion and alignment modules. Experiments on multiple urban datasets show that SAMC achieves average improvements of approximately 17.2%, 14.2%, and 5.9% compared to the state-of-the-art baselines on the tasks of regional popularity prediction, service demand prediction, and land use classification, respectively. Visualization analyses further confirm that SAMC enhances the discriminability, robustness, and generalizability of urban representations by embedding structural priors and adopting multi-stage coordinated optimization. Moreover, SAMC achieves a favorable tradeoff between computational efficiency and predictive performance.
