We hereby correct an error in Ref.[2], in which we studied the influence of various parameters that affect the generalization performance of fuzzy models constructed using the mixed fuzzy rule formation method[1].
On page 196, the last equation that computes the normalized loss in volume Vnormi contains an error. The last term of the formula must be replaced by the ratio of both distances:
Vnormi ¼dið~x;RÞ Qn
j¼1;j6¼idjð~x;RÞ Qn
j¼1djð~x;RÞ ¼dið~x;RÞ di ð~x;RÞ:
Readers are asked to substitute this equation. The authors apologize for this error and any inconvenience this may have caused.
