Validation of CBL Principles

Case Based Reasoning (C.BR) is d¢’cnwd a rather promising technology of knowledge acquisition and related knowledge processing in recent compt,ter science. Much of Ihe ("Bl{’s at t t-action is Imsed cm the charming simplicity of its ideas. In p~ticular, knowledge acquisition which is performed during CBR by incrementally collecting cases migth be under.,,tood a~s (’m~e Ba.sed Learning (CBI,}. The main goal of this paper consists in the applicat icm of validation scetmrios to the investigation of principles of CBI,. For this purpose, the domain of formal languages is used. where CBR is st raight forwardly formalized to allow for ajustitied assessment uf f’.B[, principles, h i.,, demoostrated that ¢nte of the key prim’iph,s of impruving case bases dm’ing CBR is not valid. seen h’om t he viewpoint of a correct learning. Two attempts of principle refinement are underl.akt.n and vzdidat.ed sub.-,equentl.v. For the special domain. an improvement is gained.
