UrbanCLIP: Learning Text-enhanced Urban Region Profiling with Contrastive Language-Image Pretraining from the Web [WWW 2024]
This repo is the implementation of our manuscript entitled UrbanCLIP: Learning Text-enhanced Urban Region Profiling with Contrastive Language-Image Pretraining from the Web (Accepted by the Web Conference 2024).
This repository will be kept under development for better usage. The dataset is under refinement (Part of the current data could be pseudo-data for testing only), but our team has also released a toolkit named UrbanCLIP Dataset Toolkit, a comprehensive tool chain designed to facilitate the collection, processing, and integration of satellite imagery and associated metadata for urban analysis.
Stay tuned for more updates!
【NEWS！】 Our team extended our work to a more comprehensive scope. More details can be found in the paper entitled UrbanVLP: A Multi-Granularity Vision-Language Pre-Trained Foundation Model for Urban Indicator Prediction, where we will release the dataset and code base soon.
【NEWS！】 Our team investigated the Deep Learning for Cross-Domain Data Fusion in Urban Computing: Taxonomy, Advances, and Outlook. Welcome any feedback!
