S06E03 Down to Earth: Revving up AI in Geoscience: The Hardware Revolution Dec 18, 2024

Show notes

When machine learning was first invented, the infrastructure for processing earth observation data was incredibly slow, often taking days or weeks to generate results. But recent breakthroughs in hardware and software have revolutionized our ability to collect, process, and analyze geospatial data, unlocking new possibilities for research, mapping, and environmental monitoring. At the forefront of this revolution is NVIDIA, whose innovative technologies are transforming the field. In this episode, we explore the latest advancements in GeoAI hardware and architectures with Dr. May Casterline, Principal Solutions Architect with NVIDIA, and Dr. Brent Bartlett, Senior Solutions Architect at NVIDIA. Together, they share insights on how NVIDIA's unique solutions are enabling faster, more accurate, and more insightful geospatial data processing. We also examine what this means when it comes to challenges like the data bottleneck, and the ways NVIDIA is approaching these problems from a new perspective.

S06E02 Down to Earth: AI’s Secret Sauce: Quality Data Dec 11, 2024

Show notes

We’ve heard repeatedly that reliable, validated training data is one of the most important, and also most challenging components of ensuring AI models provide accurate outputs. How are we overcoming this challenge? Through Data-centric AI! Data-centric AI emphasizes the value of good data rather than model. So what are some data-centric AI approaches? We speak to Dr. Manil Maskey, Data Science and Innovation Lead, NASA Office of Chief Science Data Officer and Dr. Rajat Shinde, Computer Scientist Level IV, NASA IMPACT, University of Alabama in Huntsville to find out!
