ABSTRACT
The aim of the study was to determine the
success factors of oral cancer susceptibility prediction using fuzzy models.
Three fuzzy prediction models including fuzzy logic, fuzzy neural network and
fuzzy linear regression models were constructed and applied to a Malaysian oral
cancer data set for cancer susceptibility prediction. The three models’
prediction performances were evaluated and compared. All the three fuzzy models
were found to have 64% prediction accuracies for 1-input and 2-input predictor
sets. However, when the number of input predictor set was increased to 3-input
and 4-input, both fuzzy neural networks’ and fuzzy linear regression’s prediction
accuracies increased to 80%, while fuzzy logic prediction accuracy remains at
64%. Fuzzy linear regression model was found to have the capability of
quantifying the relationships between input predictors and the predicted
outcomes and also suitable for small sample size. Fuzzy neural network model on
the other hand, handles ambiguous relationship between variables well but lacks
the ability to describe input-output association. The third model, fuzzy logic,
is easy to construct but highly dependent on human expert-input. The outcome of
this study is a computer-based prediction tool which can be used in cancer
screening programs.

ABSTRAK
Matlamat kajian ini
adalah untuk mengenal pasti faktor kejayaan dalam menentukan kecenderungan
terjadinya kanser mulut menggunakan model kabur. Tiga model kabur termasuk model mantik kabur, rangkaian neuro-kabur
dan regresi kabur telah dibangun dan diaplikasikan ke atas data kanser mulut di
Malaysia bagi tujuan menentukan kemungkinan terjadinya kanser. Kejituan ramalan terjadinya kanser mulut untuk ketiga-tiga model
diukur dan dibandingkan. Ketiga-tiga model kabur
didapati memberikan 64% kejituan ramalan semasa diuji menggunakan satu dan dua
faktor penentu. Walau bagaimanapun, apabila bilangan faktor penentu
ditambah kepada tiga dan empat, kejituan ramalan model rangkaian neuro-kabur
dan regresi kabur meningkat kepada 80% tetapi kejituan ramalan model mantik
kabur kekal di paras 64%. Model regresi kabur mampu mengukur kuantiti hubung
kait di antara faktor penentu dengan hasilannya dan ia juga sesuai digunakan untuk sampel yang kecil. Model
rangkaian neuro-kabur mengambil kira hubungan ketidaktentuan di antara faktor
penentu dan hasilannya tetapi tidak mempunyai keupayaan mengukur kuantiti
hubung kait di antara mereka. Model ketiga iaitu mantik kabur pula mudah
untuk dibangunkan tetapi terlalu bergantung kepada input pakar. Kajian ini menghasilkan satu alat pengukur berasaskan komputer yang
boleh digunakan bagi tujuan saringan pesakit kanser.
