• ❌ Ignoring Data Quality: No model can fix bad data. Prioritize data cleaning and validation.
• 📉 Feature Neglect: Poor feature engineering limits model power. Invest time creating meaningful variables.
• 🛠️ Poor Hyperparameter Tuning: Default settings rarely offer optimal results. Use grid or randomized search methods.
• 🔍 Lack of Model Explainability: Combine ML with interpretability tools (SHAP, LIME) to build trust.
• ⏰ Skipping Model Monitoring: Markets evolve; models must too. Automate re-training and set alerts for performance drops.

How to Use This Knowledge in Your Day-to-Day Business?

Start by identifying forecasting areas where errors cause big losses or decisions depend heavily on predictions. Then apply a hybrid approach—build baseline traditional models and slowly integrate ML techniques.

As an illustration, a European retailer implemented a gradient boosting machine to forecast inventory needs alongside ARIMA models. The combined approach slashed stockouts by 23%. This “best of both worlds” analogy is like having a seasoned captain and a cutting-edge autopilot working together for the smoothest voyage.
