Kaba küme teorisi belirsizliğe matematiksel bir
yaklaşım olarak düşünülmüş; yararlı ve etkili bir araç olarak çeşitli bilim
alanlarında kullanılmaktadır. Lineer cebirde yer alan lineer bağımlılık, lineer
bağımsızlık, taban, rank gibi temel kavramlarının genelleştirilmesi Matroid
teorisiyle olanaklı olmuştur. Bu çalışmada 
bir bağıntıdan oluşturulan matroid için öncül komşuluklara dayalı üst
yaklaşım sayısal fonksiyonu tanımlanarak genelleştirilmiş kaba kümelerle ilişkileri
incelenmiştir.

Anahtar Kelimeler

Obtaining Upper Approximation Numbers with Predecessor Neighborhoods

Öz

Rough set theory is considered as a mathematical approach to uncertainty
as a useful and effective tool in various fields of science. The generalization
of the basic concepts such as linear dependence, linear independence, base and
rank in linear algebra is possible by matroid theory. In this study, the upper
approximation number function based on predecessor neighborhoods will be
defined for the matroid generated from a relation and generalized rough sets
associations will be examined.
