`I am using ANFIS in Matlab to predict load values based on three inputs. However, many outputs are negative or sometimes unrealistic (very high or very low – outside the range on which the ANFIS is trained). It is to be noted that nor negative neither high values are included in the learning data. I tried several things to address these problems but whatever I did, the outputs did not get any better.
Kindly, as expert in ANFIS, can you advice me how to overcome this problem?
