  • Gradient Boosting Machines (GBM): Utilized for its high accuracy and predictive efficiency, particularly in handling non-linear relationships.
• Performance Metrics:
  • Mean Absolute Error (MAE): Measured the average magnitude of errors in the predictions, ensuring minimal deviation from actual sales.
  • Root Mean Squared Error (RMSE): Quantified the model’s prediction error, providing insights into the variance in predictions.
  • R-squared: Assessed the proportion of variance explained by the model, indicating the model’s overall effectiveness.

1. Data Cleaning:
   • Handled missing values and outliers to ensure the integrity of the dataset.
   • Standardized and normalized the data to maintain consistency across all features.
   • Corrected inconsistencies and errors, enhancing the quality and reliability of the data.
2. Feature Engineering:
   • Created new features to capture trends and patterns that could improve model performance.
   • Encoded categorical variables and scaled numerical features to facilitate better learning by the models.
3. Model Development:
   • Trained multiple machine learning models, including Linear Regression, Random Forest, and GBM, to identify the best performing model.
   • Tuned hyperparameters using grid search and random search techniques to optimize model performance.
4. Model Evaluation:
   • Evaluated models using MAE, RMSE, and R-squared metrics to determine the most accurate and reliable model.
   • Conducted cross-validation to ensure the model’s generalizability to new data.
5. Model Deployment:
   • Implemented the best-performing model into the production environment, ensuring seamless integration with existing systems.
   • Set up performance monitoring to continuously track the model’s accuracy and reliability, making adjustments as needed based on new data and feedback.
6. Performance Monitoring:
