Welcome to DeepSpatial 2022

3rd ACM SIGKDD Workshop on Deep Learning for Spatiotemporal Data, Applications, and Systems
August 15, 2022
Room 204C
KDD-organized Conference

Aims and Scope

The significant advancements in software and hardware technologies stimulated the prosperities of the domains in spatial computing and deep learning algorithms, respectively. Recent breakthroughs in the deep learning field have exhibited outstanding performance in handling data in space and time in specific domains such as image, audio, and video. Meanwhile, the development of sensing and data collection techniques in relevant domains have enabled and accumulated large scale of spatiotemporal data over the years, which in turn has led to unprecedented opportunities and prerequisites for the discovery of macro- and micro- spatiotemporal phenomena accurately and precisely. The complementary strengths and challenges between spatiotemporal data computing and deep learning in recent years suggest urgent needs to bring together the experts in these two domains in prestigious venues, which is still missing until now.

This workshop will provide a premium platform for both research and industry to exchange ideas on opportunities, challenges, and cutting-edge techniques of deep learning in spatiotemporal data, applications, and systems.

    Climate change and pollutant emissions continue to worsen our breathing air, causing severe health problems for national and global citizens including ~ 10 million premature death annually and many more with relevant disease and longer term health impact. High resolution and fidelity data is desperately needed to support decision making to mitigate such health impact. Several questions that came to decision making need include a) how to better detect and forecast air quality events at community level, b) how to identify the correlation spatiotemporally between various breathing disease and the air quality patterns, c) how to develop relevant policies and a rapid response system that can help mitigate the impact of air pollution to the vulnerable communities to improve their resilience and sustainability. Taking these questions, this talk will introduce the popular air quality datasets, processing needs and the opportunities and challenges for machine learning such as research aspects of training datasets, dynamic, causal, multi-model, and multi-source methods.

    Speaker Bio:

    Chaowei Phil Yang is Professor of GIScience at George Mason University. His research focuses on utilizing spatiotemporal principles/patterns to optimize computing infrastructure to support science discoveries and engineering development. He has been funded as PI by multiple resources such as NSF and NASA with over $20M expenditures. He published over 300 papers, edited six books and 10+ special issues for international journals. His publications have been among the top five cited and read papers of IJDE and CEUS. His PNAS spatial computing definition paper was captured by Nobel Intent Blog in 2011. He has led several teams who impact GIScience profoundly. For example, he led a 3-member team who developed GeoServNet at Univ. of Calgary. The software was evolved into the core of GeoTango, which was purchased by Microsoft as the origin of Virtual Earth/Bing Maps. He furthers this innovation process by encouraging and creating startups with his students and collaborators. He has placed eight tenure line Professors in the U.S. and 15 Associate or Full Professors internationally including top GIScience departments such as Penn State, Univ. of Wisconsin- Madison, Arizona State, and Wuhan Univ. He also served in many public positions, such as the President of the CPGIS (2004-2005) and the chair of UCGIS research committee (2012-2014). He received multiple national and international awards, such as the Environment Stewardship Award in 2009 from President Obama. He founded NSF I/UCRC for spatiotemporal thinking, computing and applications with a group of international leaders from UCSB, Harvard, and GMU. The spatiotemporal innovation center receives over $2M/year research funding in collaboration with agencies and industry to build the national and international spatiotemporal infrastructure.


    Data streams satellites, phones, and other digital devices contain a wealth of information relevant to sustainability goals. Modern AI techniques have the potential to yield accurate, inexpensive, and highly scalable models to inform research, policy, and business decisions. A key challenge, however, is the lack of large quantities of labeled data that often characterize successful machine learning applications. In this talk, I will present approaches for learning useful spatio-temporal models in contexts where labeled training data is scarce or not available at all. I will show applications to predict key socio-eocnomic indicators, monitor agricultural productivity, map infrastructure access, predict population health measures in data poor areas, and discuss how these insights are being used to improve decisions on the ground.
