โœ… Advanced SQL (Subqueries & CTEs) ๐Ÿ—„๏ธ๐Ÿ”ฅ ๐Ÿ‘‰ Now we move to advanced SQL concepts heavily used in: โœ” Data Analysis โœ” Reporting โœ” Dashboards โœ” Interviews ๐Ÿ”น 1. What is a Subquery? A subquery is a query written inside another query. ๐Ÿ‘‰ Also called: โœ… Nested Query ๐Ÿ”ฅ 2. Example of Subquery ๐Ÿ‘‰ Find employees earning above average salary. SELECT name, salary FROM employees WHERE salary > ( SELECT AVG(salary) FROM employees ); How it works: 1๏ธโƒฃ Inner query calculates average salary 2๏ธโƒฃ Outer query filters employees ๐Ÿ”น 3. Types of Subqueries โœ” Single-row subquery โœ” Multiple-row subquery โœ” Correlated subquery ๐Ÿ”น 4. Correlated Subquery โญ ๐Ÿ‘‰ Inner query depends on outer query. SELECT e1.name FROM employees e1 WHERE salary > ( SELECT AVG(salary) FROM employees e2 WHERE e1.department = e2.department ); ๐Ÿ”ฅ 5. What is a CTE? CTE = Common Table Expression ๐Ÿ‘‰ Temporary result set used inside a query. Defined using: WITH ๐Ÿ”น 6. Example of CTE โญ WITH avg_salary AS ( SELECT AVG(salary) AS avg_sal FROM employees ) SELECT * FROM employees WHERE salary > ( SELECT avg_sal FROM avg_salary ); ๐Ÿ”น 7. Why Use CTEs? โœ” Makes queries readable โœ” Simplifies complex logic โœ” Easier debugging ๐Ÿ”น 8. Difference Between Subquery & CTE Subquery : Nested inside query CTE : Defined separately Subquery : Harder to read CTE : More readable Subquery : Repeated logic possible CTE : Reusable ๐Ÿ”น 9. Why This is Important? โœ” Frequently asked in interviews โœ” Used in dashboards & analytics โœ” Important for real-world SQL projects ๐ŸŽฏ Todayโ€™s Goal โœ” Understand subqueries โœ” Learn correlated subqueries โœ” Understand CTEs โœ” Write cleaner SQL queries ๐Ÿ‘‰ SQL Notes: https://whatsapp.com/channel/0029VbCyzS02ZjCwoShXXc2j ๐Ÿ’ฌ Tap โค๏ธ for more!

โœ… Cross Validation & Hyperparameter Tuning ๐Ÿค–โš™๏ธ ๐Ÿ‘‰ Building a model is not enough. We must also make sure it performs well on unseen data. This is done using: โœ” Cross Validation โœ” Hyperparameter Tuning ๐Ÿ”น 1. What is Cross Validation? Cross Validation checks how well a model generalizes to new data. ๐Ÿ‘‰ Instead of using only one train-test split, data is divided multiple times. ๐Ÿ”ฅ 2. K-Fold Cross Validation โญ How it Works: 1๏ธโƒฃ Split data into K parts (folds) 2๏ธโƒฃ Use one fold for testing 3๏ธโƒฃ Use remaining folds for training 4๏ธโƒฃ Repeat until every fold is tested โœ… Example If K = 5: โ€ข 4 folds โ†’ Training โ€ข 1 fold โ†’ Testing Repeated 5 times. ๐Ÿ”น 3. Why Cross Validation is Important? โœ” Better model evaluation โœ” Reduces overfitting risk โœ” More reliable accuracy ๐Ÿ”น 4. Implementation (Python) from sklearn.model_selection import cross_val_score from sklearn.linear_model import LogisticRegression model = LogisticRegression() scores = cross_val_score(model, X, y, cv=5) print(scores) ๐Ÿ”ฅ 5. What are Hyperparameters? ๐Ÿ‘‰ Hyperparameters are settings controlled before training the model. Examples: โœ” Number of trees in Random Forest โœ” Value of K in KNN โœ” Learning rate ๐Ÿ”น 6. Hyperparameter Tuning ๐Ÿ‘‰ Finding the best settings for the model. ๐Ÿ”ฅ 7. Grid Search โญ Grid Search tries multiple parameter combinations automatically. from sklearn.model_selection import GridSearchCV โœ… Example params = { "n_neighbors": [3,5,7] } ๐Ÿ‘‰ Tests different K values in KNN. ๐Ÿ”น 8. Why Tuning is Important? โœ” Improves model performance โœ” Increases accuracy โœ” Helps build optimized ML systems ๐ŸŽฏ Todayโ€™s Goal โœ” Understand cross validation โœ” Learn K-Fold method โœ” Understand hyperparameters โœ” Learn Grid Search basics ๐Ÿ’ฌ Tap โค๏ธ for more!
