Modified Kohonen network algorithm for selection of the initial centres of Gustafson-Kessel algorithm in credit scoring
Sameer, F1, Abu Bakar, M.R2.
Credit risk assessment has become an important topic in financial risk administration. Fuzzy clustering
analysis has been applied in credit scoring. Gustafson-Kessel (GK) algorithm has been utilised to cluster
creditworthy customers as against non-creditworthy ones. A good clustering analysis implemented by
good Initial Centres of clusters should be selected. To overcome this problem of Gustafson-Kessel (GK)
algorithm, we proposed a modified version of Kohonen Network (KN) algorithm to select the initial
centres. Utilising similar degree between points to get similarity density, and then by means of maximum
density points selecting; the modified Kohonen Network method generate clustering initial centres to get
more reasonable clustering results. The comparative was conducted using three credit scoring datasets:
Australian, German and Taiwan. Internal and external indexes of validity clustering are computed and
the proposed method was found to have the best performance in these three data sets.
