Read the source ↓What the company did
Google Cloud publishes Coolblue’s account of using AlphaEvolve to improve its 28-day demand-forecasting pipeline. The AI proposes and evaluates feature engineering, target preprocessing and regression-model combinations, with an evaluation metric covering both the first seven days and the full horizon while penalizing underforecasting.
How it went
Coolblue’s data scientist reports more than a 5% reduction in forecast error (WMAPE) against the existing production forecast after about 200 iterations. This is a customer-reported forecast improvement, not an independently reproduced result or a quantified reduction in stockouts.
Worth knowing
- The resulting forecast supports bulk purchasing and stock planning; the metric’s penalty reflects the cost of insufficient availability.
- For your desk: Compare errors by SKU and horizon, including underforecasts, before changing purchases. Check whether aggregate gains hide shortages on important products.
