Module III - Rule Based Systems

  Understanding Rule-Based Systems in Problem Solving: A Comprehensive Guide In today's rapidly evolving world of artificial intelligence and computational problem-solving, rule-based systems continue to play a crucial role despite the rise of machine learning approaches. As a foundational concept in AI, understanding rule-based systems provides valuable insights into how computers can emulate human reasoning processes. This blog post explores what rule-based systems are, how they work, and why they remain relevant in modern problem-solving scenarios. What Are Rule-Based Systems? At their core, rule-based systems (also known as production systems or expert systems) are a type of artificial intelligence approach that uses a set of predefined rules to analyze information and make decisions. These systems attempt to capture human expertise in a specific domain and apply it consistently to solve problems within that domain. A rule-based system consists of three primary components: A k...

Module III - Heuristic Classifications

  Heuristic Classifications in Problem Solving: A Comprehensive Guide When faced with complex problems, humans rarely evaluate every possible solution. Instead, we use mental shortcuts—or heuristics—to find solutions that are "good enough" without exhausting our cognitive resources. These problem-solving strategies have not only shaped human thinking but have also been formalized and classified in the field of artificial intelligence and cognitive science. This blog explores the fascinating world of heuristic classifications in problem solving, providing clear explanations, practical examples, and visual representations to help understand these powerful techniques. What Are Heuristics? Heuristics are problem-solving approaches that use readily accessible information to guide decision-making when finding optimal solutions is impractical or impossible. Often described as "rules of thumb," heuristics provide efficient, though not always perfect, ways to tackle comp...

  Understanding Uncertainty Modeling in Expert Systems Introduction Expert systems are AI-driven programs designed to emulate human decision-making in specialized domains like medicine, finance, and engineering. However, real-world problems often involve incomplete or ambiguous information, leading to uncertainty.  Uncertainty modeling  helps expert systems handle such imprecise data effectively. In this blog, we’ll explore: ✔ What is uncertainty in expert systems? ✔ Why is uncertainty modeling important? ✔ Common methods for uncertainty modeling ✔ Practical examples What is Uncertainty in Expert Systems? Uncertainty arises when an expert system lacks complete or precise data to make a definitive decision. Common sources of uncertainty: 1. Information and Knowledge: Lack of information: Decision-making can be hampered by insufficient data or incomplete knowledge about the situation, potential outcomes, or available alternatives. Too much informa...
