Michalski, Ryszard S.2006-11-062006-11-061974-05"Variable-Valued Logic: System VL1," Proceedings of the 1974 International Symposium on Multiple-Valued Logic, West Virginia University, Morgantown, West Virginia, pp.323-346, May 29-31, 1974.https://hdl.handle.net/1920/1517The paper defines the concept of a variable-valued logic (VL) system and discusses in detail one specific VL system called VL1. The main motivation for the development of the VL system concept is to construct a well-defined, general formal system unifying various combinatorial problems and adequate, in particular, for problems of 'learning from examples' (problems which are of special interest to areas of pattern recognition and machine intelligence).1612 bytes2882179 bytestext/xmlapplication/pdfen-USVariable-valued logicMany-valued logicSwitching functionsDisjunctive normal formsInductive systemsPresentation
