Machine Learning Methods, Pragmatically Applied
Gradient boosting and random forests capture nonlinear effects between price, promotions, and calendar events. Feature importance spotlights true drivers, while monotonic constraints keep predictions aligned with known economic behavior.
Machine Learning Methods, Pragmatically Applied
Sequence models like LSTM and Temporal Convolutional Networks handle long-term dependencies, holidays, and promotions. Pair them with robust baselines and backtesting to avoid seductive but brittle accuracy gains.
Machine Learning Methods, Pragmatically Applied
Calendar flags, macro variables, and cohort tags often outperform fancy architectures. Use rolling-origin cross-validation to mimic real forecasting, and monitor drift so yesterday’s winning model doesn’t quietly decay.
