---

Linear Regression

Linear regression is often the first algorithm beginners learn.

It predicts continuous numerical values.

Examples:

• House price prediction
• Revenue forecasting
• Sales prediction
• Temperature estimation

The core regression formula:

$𝑦=𝑚𝑥+𝑏$

$𝑚$

$𝑏$

Where:

• $𝑦$ = predicted output
• $𝑚$ = slope
• $𝑥$ = input feature
• $𝑏$ = intercept

The course teaches regression both theoretically and practically using Scikit-learn and Python.

---

Logistic Regression

Logistic regression is used for classification problems.

It predicts categories such as:

• Yes/No
• Fraud/Not Fraud
• Spam/Not Spam

The course includes multiple practical sessions dedicated to logistic regression implementation in Python.
