arXiv:2606.20167v1 Announce Type: new Abstract: Spatial prediction tasks are often limited by a lack of high-quality labelled ground-truth observations. To overcome this challenge, self-supervised pre-training is a possible solution, with contrastive learning dominant for location encoders. Those approaches usually align geographic coordinates with just one additional modality. We propose two multimodal contrastive learning architectures: Multimodal Embedding via Location Tying (MELT) and Sequential Alternating Location Training (SALT). These architectures expand this framework beyond two moda
The paper tackles a critical limitation in spatial prediction tasks, driven by increasing demand for sophisticated environmental modeling and the growing maturity of self-supervised learning techniques in AI.
Improving location encoders will enhance the accuracy and efficiency of AI applications in climate science, urban planning, and resource management, fields that heavily rely on high-quality spatial data.
The proposed MELT and SALT architectures introduce more sophisticated multi-modal contrastive learning for geographic data, potentially leading to more robust and less data-intensive spatial AI models.
