Task 5- M&M Presentation Flashcards
Which system has a higher representational power- logic or rule-based systems?
- all in all: logic based system
- unlike logic, rule-based systems can also easily represent strategic information about what to do
What is the fundamental operation of both logic-based and rule-based systems?
- logic-based systems: fundamental operation of thinking is logical deduction
- rule-based systems: fundamental operation of thinking is search
What do people rely on when solving problems?
people rely on heuristics
What can rule-based processing be?
can be either serial or parallel
What does bidirectional search mean?
combines working forward from the starting place with working backward from the goal
What is ‘inductive generalization’?
one way in which a rule can be learned
-> examples are summarized by means of a rule
What does chunking in the SOAR model and composition in the ACT model mean?
chunking rules into a general rule
What is specialization?
existing rule is modified to deal with a specific situation
What is abductive reasoning?
rule is run backward to provide a possible explanation of what happened
What is incremental learning? How can rules be used to describe it?
- Rules can also be used to describe slow incremental learning
- if each rule has a numerical value representing the usefulness or plausibility associated with it
- > the more a rule gets used successfully, the more it is judged to be plausible and useful
Which system has the most psychological plausibility?
Rule-based systems
How did Anderson related ACT-R to neural systems?
- production rules are implemented by the brain’s basal ganglia
- matched rules matched are stored in a set of buffers in the PFC
What are logic based models better at?
representational power
What are rule based models better at?
computational power and psychological plausability
