I implemented the FCM and KFCM in java for clustering of dataset. However I obtained same results for Obj Function:Code in KFCM:
object += 2*(Math.pow(u[i * pattern+j], m) * K(v1, v2, dimension) * K(v1, v2, dimension));
Distance code:
b= (v1[i] - v2[i]) * (v1[i] - v2[i]);
result+=(1-Math.exp(-b/4) )
