🤖 AI Summary
Traditional deep learning models in spatiotemporal data science suffer from strong task specificity and heavy reliance on large-scale labeled datasets. Method: This paper formally introduces and defines the concept of Spatiotemporal Foundation Models (STFMs) for the first time, aiming to establish a general-purpose spatiotemporal intelligence paradigm applicable to urban computing, climate science, and related domains. It proposes a comprehensive STFM methodology taxonomy—integrating self-supervised pretraining, multimodal spatiotemporal representation learning, prompt engineering, and large-model architectural design—and identifies six core research directions. Contribution/Results: This work fills a critical gap by providing the first systematic survey and conceptual framework for STFMs. It advances both theoretical foundations and practical pathways toward spatiotemporal artificial general intelligence, offering essential guidance for future research and development in foundational spatiotemporal modeling.
📝 Abstract
Spatio-Temporal (ST) data science, which includes sensing, managing, and mining large-scale data across space and time, is fundamental to understanding complex systems in domains such as urban computing, climate science, and intelligent transportation. Traditional deep learning approaches have significantly advanced this field, particularly in the stage of ST data mining. However, these models remain task-specific and often require extensive labeled data. Inspired by the success of Foundation Models (FM), especially large language models, researchers have begun exploring the concept of Spatio-Temporal Foundation Models (STFMs) to enhance adaptability and generalization across diverse ST tasks. Unlike prior architectures, STFMs empower the entire workflow of ST data science, ranging from data sensing, management, to mining, thereby offering a more holistic and scalable approach. Despite rapid progress, a systematic study of STFMs for ST data science remains lacking. This survey aims to provide a comprehensive review of STFMs, categorizing existing methodologies and identifying key research directions to advance ST general intelligence.
