BIB-VERSION:: CS-TR-v2.0 ID:: STAN//CS-TR-69-125 ENTRY:: November 27, 1995 ORGANIZATION:: Stanford University, Department of Computer Science TITLE:: Grammatical complexity and inference TYPE:: Technical Report AUTHOR:: Feldman, Jerome A. AUTHOR:: Gips, James AUTHOR:: Horning, James J. AUTHOR:: Reder, Stephen DATE:: June 1969 PAGES:: 110 ABSTRACT:: The problem of inferring a grammar for a set of symbol strings is considered and a number of new decidability results obtained. Several notions of grammatical complexity and their properties are studied. The question of learning the least complex grammar for a set of strings is investigated leading to a variety of positive and negative results. This work is part of a continuing effort to study the problems of representation and generalization through the grammatical inference question. Appendices A and B and Section 2a.0 are primarily the work of Reder, Sections 2b and 3d of Horning, Section 4 and Appendix C of Gips, and the remainder the responsibility of Feldman.
