MetaStreet: Semi-Supervised Multimodal Learning for Street-Level Socioeconomic Prediction

ICML 2026poster

Predicting street-level socioeconomic indicators from street view imagery is fundamental to urban planning. Existing methods typically extract visual features via pretrained encoders and propagate information through graph-based learning, but they fail to fully exploit the structured, task-relevant,…

Black-Box Test-Time Prompt Tuning for Vision-Language Models

AAAI 2025technical

Test-time prompt tuning (TPT) aims to adjust the vision-language models (e.g., CLIP) with learnable prompts during the inference phase. However, previous works overlooked that pre-trained models as a service (MaaS) have become a noticeable trend due to their commercial usage and potential risk of mi…

Cross-City Latent Space Alignment for Consistency Region Embedding

ICML 2025poster

Learning urban region embeddings has substantially advanced urban analysis, but their typical focus on individual cities leads to disparate embedding spaces, hindering cross-city knowledge transfer and the reuse of downstream task predictors. To tackle this issue, we present Consistent Region Embedd…
