Ziheng Sun is a research assistant professor in Center for Spatial Information Science and Systems. He is a practitioner of using the latest technologies including artificial intelligence and high-performance computing to seek for answers to the questions in geoscience. He has published 11 first-author papers on renowned journals in geoscience. He has invented RSSI, a novel index for artificial object recognition from high resolution aerial images, and proposed parameterless automatic classification solution for reducing the parameter-tuning burden on scientists. He has successfully used long short-term memory to learn the seasonal changes to better recognize crops. He has worked on several federal-funded projects to build geospatial cyberinfrastructure systems for better disseminating, processing, visualizing, and understanding spatial big data.
