    ## Project Title: 🏦Customer Churn Prediction | EDA + Model 💻:
    
    ##### 📊 Data Exploration and Preprocessing:
    - Preparing data by encoding categorical features like "ProductCategory" and "ProductBrand" and scaling numerical data such as "price" and "rating", as the dataset has minimal outliers or missing values.
    - Analyzing trends in **Product Categories**, **Brands**, **Prices**, **CustomerAge**, etc., to identify influential factors.
    
    ##### 🤖 Predictive Modeling:
    - **Target Variable**: Predicting key metrics like *PurchaseIntent*.
    - **Model Selection**: Building ML models such as **KNN**, **Logistic Regression**, and **Support Vector Machine** for classification tasks.
    - **Feature Engineering**: Extracting insights from **ProductCategory**, **ProductBrand**, and label encoding.
    
    ##### 📈 Model Evaluation:
    - Comparing model performance using metrics like **accuracy**, **F1 score**, or **Log-loss score**, depending on the task.
    - Employing techniques like **hyperparameter tuning** and **cross-validation** for optimization.
    
    ##### Customer churn prediction helps businesses identify customers at risk of leaving, enabling proactive retention strategies. By analyzing patterns like purchase behavior and customer feedback, it aids in tailoring personalized offers to reduce churn. This ultimately enhances customer satisfaction, loyalty, and profitability .
