Earth Day at KDD

Calling all earth and environmental scientists, students and researchers! Please join us at Earth Day on August 5th. The location is Arteaga- Street Level, Egan.

Why at SIGKDD? Why now?

Earth is home to all of us. However, our beloved planet and civilization is facing major challenges from climate change and environmental degradation. Extreme events are becoming more extreme and more frequent. Surface water has more pollution and greenhouse gases have increased in the atmosphere. Moreover, the largest freshwater source on Earth, polar ice-caps and glaciers are losing ice, leading to sea-level rise.

Knowledge discovery and data mining (KDD) is crucial to addressing these and other challenges facing our changing planet. For example, Earth data (i.e. geo-referenced data such as in-situ and remotely sensed Earth observations, census, trajectories) records and helps in understanding biological, physical, and social changes. It can help forecast rates of sea level change in polar ice shelves, predict critical atmosphere and geospace events. It is also important for many societal priorities including security, public health, smart cities, transportation, climate, environment, food, energy, water.

Earth data have unique characteristics that bring challenges to data science such as spatio-temporal auto-correlation, spatial variability, scale-dependence, modifiable areal unit problem, etc. Earth Day will bring together thought leaders in academia, industry and government to explore this area and discuss opportunities to overcome the challenges that Earth faces today.

Earth Day Session Program

Morning: Three earth-related workshops

Fragile Earth: Theory Guided Data Science to Enhance Scientific Discovery

Data Mining and AI for Conservation

Urban Computing


12:00-1:00 pm- Lunch


1:30 pm-1:45 pm: Welcome, Rationale for Earth Day theme


1:45 pm-3:00 pm: Session 1: Importance of Earth data sets and use cases

Background: Earth data (e.g., remote sensing imagery, GPS time service, location traces) has already transformed our lives by improving monitoring of global weather and agriculture for early warning of hurricanes and inclement weather as well as food shortage risks due to crop stresses or failures. Further, with 2 billion [2] receivers in use for location and time services, the GPS has become a critical infrastructure for the world economy for use cases ranging from precision agriculture to navigation to ride sharing to smart cities. These success stories are only a beginning and many transformative opportunities lie ahead. For example, the 2011 Mckinsey Big Data report [4] estimated that location trace data will generate about $600 billion annually by 2020. In addition, 2019 U.S. national academy report projects $1.6 trillion in savings for energy generation and use from earth data by 2035 [1]. Furthermore, government and industry have recently started major initiatives such as NASA Earth Exchange, Amazon’s Earth on AWS, Google Earth Engine, Microsoft’s AI for Earth, and NSF Navigating the New Arctic for meeting grand challenges facing our changing planet such as conservation, climate change, and environmental sustainability. This session will explore the tremendous value of Earth data for civil society, prosperity and good governance via a keynote and a panel discussion.

4:00 pm - 5:15 pm: Session 2 : Earth Day related Data Mining challenges and opportunities

Background:Data mining methods have found success in analyzing many complicated systems, such as e-commerce, and use cases explored in the Earth Day aligned SIGKDD workshops. However, many questions remain open due to unique Earth data challenges such as spatio-temporal auto-correlation, heterogeneity, scale-dependence, measurement errors, modifiable areal unit problem, etc [2,3,5]. For example, a recent Geo-Physical letter paper [1] noted that “failure to account for dependence between [Physical] models, variables, locations and seasons yield misleading results”. Additional challenges are noted in recent community papers from the NSF IS-GEO Research Coordination Network [2] and University Consortium for Geographic Information Science [3]. For example, Gerrymandering court debates [6] also raise transparency concerns for the risk of altering statistical results by changing the choice of spatial partitions. This session explores these challenges and opportunities via a keynote and a panel discussion.
