Large-scale Benchmark Datasets for Geo-scientific Discovery: AI Challenges & Opportunities
Advances in deep learning and foundation models have continued to set new expectations for general tasks and bring new potential to harness geospatial big data for Earth monitoring and geoscience discovery, benefiting broad sectors including agriculture, energy, water, disaster response, and urban planning. However, direct applications of deep learning often fall short due to challenges posed by geospatial data, including spatial variability that can significantly weaken the replicability of AI models over space, limited and expensive-to-collect training samples, and the misalignment between pretraining and downstream tasks. To accelerate new AI model development for addressing these challenges, large-scale AI-ready benchmark datasets are essential to enable model training, testing, and comparison under different scenarios of practical importance to domain experts. This talk will showcase several datasets and benchmarks we recently created and open-sourced to support AI model development, which: (1) represent large geographic scales from national, continental, to global scales; (2) cover different data modalities such as remote sensing imagery (e.g., satellites, UAV), in-situ field measurements, and physical simulations; (3) support a variety of machine learning tasks including forecasting, segmentation, and emulation; and (4) directly link to important societal applications. Moreover, I will also discuss AI challenges embedded in these benchmark datasets for large scale applications and potential opportunities in AI model developments to tackle them.
Biography
Yiqun Xie is an Assistant Professor in the Center for Geospatial Information Science, Dept. of Geographical Sciences, and an Affiliate Faculty at the AI Interdisciplinary Institute at Maryland (AIM), at the University of Maryland. He received his PhD in Computer Science at the University of Minnesota, and his research addresses challenges facing machine learning for spatio-temporal data and related scientific problems. His current work focuses on: (1) geo-aware learning for large-scale problems with cross-region variability, (2) knowledge-guided learning for data-sparse problems, and (3) foundation models for geoscientific discovery. His research is supported by NSF, NASA, and Google, and has received recognitions including the Best Paper Award from IEEE ICDM 2021, the Best Application Paper Award from SIAM Data Mining 2023, the Best Vision Paper Award (Blue Sky Ideas Award) from ACM SIGSPATIAL 2019, and highlights from the Great Innovative Ideas by CCC at CRA. He also delivered invited panel talks on GeoAI at Committee Meetings of the National Academies on Science, Engineering, and Medicine (NASEM) and the National Geospatial Advisory Committee (NGAC).
