Dive deep into supervised learning, where models are trained on labeled data. We’ll explain the concepts of regression and classification, and provide Python code examples for linear regression and logistic regression.

## 3. Unsupervised Learning

Unsupervised learning is all about discovering patterns in unlabeled data. We’ll explore clustering techniques, focusing on K-Means clustering and providing Python code examples for implementation.

## 4. Feature Engineering

Feature engineering is a critical step in preparing data for machine learning. We’ll discuss techniques for feature selection and transformation to improve model performance.

## 5. Model Evaluation

Learn how to assess the performance of machine learning models using evaluation metrics like accuracy, precision, recall, and F1-score.

## 6. Python Code Examples

### Linear Regression

We’ll walk through a Python code example that demonstrates linear regression for predicting numerical values based on input features.

```python
    # Python code for Linear Regression
    from sklearn.linear_model import LinearRegression
    from sklearn.model_selection import train_test_split

    # Load and preprocess your dataset

    # Split the data into training and testing sets
    X_train, X_test, y_train, y_test = train_test_split(X, y, test_size=0.2)

    # Create and train a linear regression model
    model = LinearRegression()
    model.fit(X_train, y_train)

    # Make predictions
    predictions = model.predict(X_test)
```
