Microsoft Research's Probabilistic Bias Correction wins top honors in global extended weather forecasting competition

LesterMackey · x · 2026-10-15

Researchers at Microsoft Research, including Lester Mackey, Alexiji Lu, and Lorin Crawford, took top honors in a global forecasting competition with their Probabilistic Bias Correction method.

Why it matters:

• Weather forecasts become unreliable past two weeks, leaving a crucial gap for farmers and others
• The method improves extended-range probabilistic forecasting and shows promise for real-world use

Announced via the official Microsoft Research account as an AI for Science highlight.
