//Characteristics of AI
It collects data, has a set of rules for using that data, has the ability to reason, and — importantly — the ability to learn and adapt, improving its own performance over time.
//Expert systems
Four parts: the knowledge base (facts), the rule base (the IF…THEN rules), the inference engine (which applies the rules to the facts) and the user interface. Used for medical diagnosis, mineral prospecting, tax advice and fault-finding.
