Propositional Logic

Propositional logic is integral to the data scientist&s;s work with automated systems of analysis, including artificial intelligence, expert systems , and application development in general. In these endeavours, it is important to convey task objectives in unambiguous logical terms, be it for architecting data flows or generating statistical reports for business decisions. A proposition is simply a statement or expression which asserts that something is true or false. The assertion may require certain conditions be met and, because mathematical symbols may be used, propositional logic may be referred to as mathematical logic or symbolic logic. The concepts of propositional logic are applicable to set logic when the predicates are replaced with sets. Therefore, to understand propositional logic with respect to data sets, relationships between data sets must be defined. Applications of logic exist throughout machine architectures and program algorithms, with logical statements comprising function conditions and their arguments (or parameters ).
