AI — Recommendation Systems
What are Expert Systems?
Programs that emulate expert decision-making.
Components
| Component | Description |
|---|---|
| Knowledge Base | Facts and rules |
| Inference Engine | Reasoning mechanism |
| User Interface | Human interaction |
Rule-Based System
rules = [
("fever", "headache", "flu"),
("fever", "rash", "measles"),
("cough", "fatigue", "cold")
]
def diagnose(symptoms):
for rule in rules:
if all(s in symptoms for s in rule[:-1]):
return rule[-1]
return "unknown"
Forward Chaining
Start from facts, apply rules to reach conclusions.
Backward Chaining
Start from goal, work backwards to find supporting facts.
Mini Practice
- Understand expert systems
- Create rule-based system
- Implement forward chaining
- Try backward chaining
