Implies propositional logic tree induction
WitrynaThe main limitation of current symbolic models is the fact that they are essentially based on classical propositional logic, which implies that data with an implicit dimensional component, such as temporal, e.g., time series, or spatial data, e.g., images, cannot be properly dealt with within the standard symbolic framework.

Witryna2.1 Syntax of propositional logic Take a set of propositional symbols P, Q, R, :::. A formula consisting of a propositional symbol is called atomic. We use t and f to denote true and false. Formulas are constructed from atomic formulas using the logical connectives1: (not) ^ (and) _ (or)! (implies) $ (if and only if) WitrynaThe Biconditional Connective On Friday, we saw that “p if and only if q” means both that p → q and q → p. We can write this in propositional logic using the biconditional connective: p ↔ q This connective’s truth table has the same meaning as “p implies q and q implies p.” Based on that, what should its truth table look like? Take a guess, …
