  1. SOAR A cognitive architecture By: Majid Ali Khan

  2. Introduction • What does SOAR stand for? • State • Operator And • Result • An architecture for constructing cognitive models

  3. Introduction • Problem spaces as a single framework for all tasks and subtasks to be solved • Production rules for representation of permanent knowledge • Objects with attributes and values for representation of temporary knowledge • Automatic subgoaling mechanism for generating goals • Chunking as learning mechanism

  4. High Level Architecture

  5. Rule Memory (permanent)

  6. Working Memory (temporary)

  7. Default Working Memory

  8. HelloWorld Rule

  9. Design Principle • The design of Soar is based on the hypothesis that all deliberate goal -oriented behavior can be cast as the selection and application of operators to a state. • A state is a representation of the current problem-solving situation; an operator transforms a state (makes changes to the representation); and a goal is a desired outcome of the problem-solving activity

  10. Operational Cycle

  11. Propose Rule

  12. Apply Rule
