“We’ve shown that with careful selection, you can guarantee optimal solutions with a small dataset, and we provide a method to identify exactly which data you need,” says Asu Ozdaglar.

Bigger datasets aren’t always better

Judah Cohen’s model won first place for the fall season in the 2025 AI WeatherQuest subseasonal forecasting competition. The winning model combined machine-learning pattern recognition with the same Arctic diagnostics Cohen has refined over decades. The model detected a potential cold surge in mid-December for the U.S. East Coast weeks before such signals typically arise. The forecast was widely publicized in the media in real-time.
