    Rule Based Decision Making Versus AI based Decision Making

    Task:
    Using the provided articles, answer the following questions:

    Article 1: Pecan Blog

    1. List six features of rule-based systems.
    2. List six main features of AI-based decision-making systems.
    3. What is the difference between Machine Learning and Artificial Intelligence?
    4. Why are AI (Machine Learning) systems considered a better approach to decision-making?

    Articles 2 & 3:

    1. What is a rule-based system?
    2. What are the advantages and disadvantages of rule-based systems?
    3. What are the applications of both rule-based and AI-based decision-making systems?
    Further Activity (Watch the Video Shared)

    A great video explaining the difference between rule-based decision-making and AI-based decision-making is "The AI vs Rule Based Debate: Understanding the Differences" on YouTube. This video explores how rule-based systems rely on predefined "if-then" rules, while AI-based systems, powered by machine learning, adapt dynamically to data and evolving scenarios. It also highlights the practical applications and limitations of both approaches, making it an excellent resource for gaining a clear understanding of their distinctions.
