β 1970s-80s: Rule-based systems and expert systems
Detailed Explanation
During the 1970s and 1980s, AI saw the emergence of rule-based systems and expert systems. Rule-based systems followed specific rules set by human experts to perform tasks. Expert systems were designed to mimic the decision-making abilities of a human expert in a particular domain. They used a knowledge base and inference rules to provide solutions or recommendations.
Examples & Analogies
Imagine a medical diagnostic tool that helps doctors by asking a series of yes or no questions. Each answer the doctor gives leads to a conclusion based on pre-defined rulesβthis is similar to how early expert systems operated, relying on a set of prescribed logic to assist in decision-making.
