- In propositional logic, what does the conjunction operator (AND) return true if and only if?
Show answer
Both propositions are true.
- What is the truth value of 'P OR NOT P' in classical propositional logic?
Show answer
Always true (it is a tautology).
- What logical inference rule allows you to conclude Q from 'P implies Q' and P?
Show answer
Modus Ponens.
- In first-order logic, what is a predicate?
Show answer
A function that returns true or false for one or more arguments.
- What does the universal quantifier (for all X) allow you to express?
Show answer
A statement that applies to every object in the domain.
- What does the existential quantifier (exists X) allow you to express?
Show answer
A statement that applies to at least one object in the domain.
- What is unification in first-order logic?
Show answer
Finding a substitution of terms for variables that makes two expressions identical.
- What is Conjunctive Normal Form (CNF)?
Show answer
A logical formula written as a conjunction (AND) of disjunctions (OR clauses).
- In inference, what does the Resolution principle allow you to derive?
Show answer
A new clause by resolving two clauses that contain complementary literals.
- What is forward chaining in inference?
Show answer
Starting from known facts and repeatedly applying inference rules to derive new facts until a goal is reached.
- What is backward chaining in inference?
Show answer
Starting from a goal and working backward to find supporting facts, stopping when known facts are reached.
- What is a Horn clause?
Show answer
A clause with at most one positive literal, written as P1 AND P2 AND ... AND Pn implies Q.
- What is a Bayesian network?
Show answer
A directed acyclic graph where nodes represent random variables and edges represent conditional dependencies.
- What is a Conditional Probability Table (CPT) in a Bayesian network?
Show answer
A table specifying the probability distribution of a variable given each combination of its parent variables.
- What does d-separation (or d-separation criterion) determine in a Bayesian network?
Show answer
Whether two variables are conditionally independent given a third variable by checking paths in the DAG.
