A machine learning engineer has developed a global air quality forecasting model focused on PM2.5 levels for the US, UK, India, and Australia. The model initially struggled with high-variance regions, but a novel "horizon aligned architecture" improved its predictive accuracy. This architecture decouples forecasting horizons and incorporates a rolling volatility matrix to prevent data leakage, resulting in a Mean Absolute Scaled Error below 1.0 globally and a 57% predictive accuracy over a 30-day horizon.
