Study Notes
Types of Reasoning
- Analogical reasoning infers conclusions by comparing and finding similarities with different situations.
- Abductive reasoning assumes general knowledge when specific information is lacking.
Logical Structures
- A sequence of statements where the final statement is validated by the preceding ones is called a logical argument.
- A syllogism in deductive logic consists of two premises followed by a conclusion.
Logic and Self-Knowledge
- Introspective logic involves self-knowledge and understanding one’s own reasoning processes.
Inference and Deduction
- From "All basketball players are tall" and "Jason is not tall," we can conclude that Jason is not a basketball player, as the premises indicate a necessary condition for being a basketball player.
Rule-Based Expert Systems
- The knowledge base in a rule-based expert system serves to store domain-specific information and rules for processing.
- Rules in a rule-based expert system are typically structured in an IF-THEN format.
Inference Engine Role
- The inference engine processes the rules and knowledge base to draw conclusions or make decisions based on input data.
Explanation Facilities
- Explanation facilities in a rule-based expert system provide justifications for decisions made by the system to enhance user understanding.
User Interface Function
- The user interface in a rule-based expert system enables interaction between the user and the system, facilitating input and output of information.
Components of Expert Systems
- While there are several main components of a rule-based expert system, non-deductive logic is NOT considered one of them.
Problem Domain vs. Knowledge Domain
- The problem domain refers to the specific issue being addressed, while the knowledge domain encompasses the information and rules relevant to solving that issue.
Advantages of Expert Systems
- Advantages of using expert systems include consistency in decision-making, availability for extended hours, and speed in processing information.
Domain Expert Role
- The primary role of the domain expert in developing an expert system is to provide expertise and knowledge, ensuring accurate rule creation and knowledge representation.
Knowledge Representation
- A common way to represent knowledge in an expert system is through production rules or logic-based frameworks.
Explanation Facility Purpose
- The primary purpose of the explanation facility in an expert system is to clarify the reasoning behind the system's conclusions, enhancing transparency.
