NSF lists this award's end date as 31 August 2028.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 December 2028.

Abstract

This proposal addresses geographic bias foundation models. Geographic bias refers to a phenomenon in which an AI model performs differently across geographic regions. This project develops a statistics-informed framework to measure and mitigate geographic bias for both task-specific GeoAI model and foundation models. Open-source software and benchmarks are developed and made freely available to help researchers and…
