Machine Learning

Machine Learning (ML) is a field of Artificial Intelligence where computers learn patterns from historical data and use those patterns to make predictions or decisions without being explicitly programmed.

Instead of writing hundreds of rules manually, we provide data, and the algorithm automatically identifies relationships within the data.

Real-World Example

Suppose you want to identify spam emails.

Traditional Programming:

1. Write rules like:
2. If email contains "Lottery", mark as spam.
3. If sender is unknown, mark as spam.

Machine Learning:

1. Feed thousands of spam and non-spam emails.
2. The model learns common characteristics automatically.
3. It predicts whether new emails are spam.
