# Rule-Based Classification
|
|
|
|
**Rule-Based Classifiers** use a set of **IF-THEN** rules to classify data.
|
|
|
|
## Structure
|
|
- **Rule**: `IF (Condition) THEN (Class)`
|
|
- *Example*:
|
|
- `IF (Age = Youth) AND (Student = Yes) THEN (Buys_Computer = Yes)`
|
|
|
|
## Extracting Rules from Decision Trees
|
|
- We can easily turn a decision tree into rules.
|
|
- Each path from the **Root** to a **Leaf** becomes one rule.
|
|
- The conditions along the path become the `IF` part (joined by AND).
|
|
- The leaf node becomes the `THEN` part.
|
|
|
|
## Advantages
|
|
- Easy for humans to understand.
|
|
- Can be created directly or from other models (like trees).
