[Anfis] Optimize FIS

Hi, I just created a file .fis .

Now, I have to optimise it through ANFIS .

My original fis is a Mamdani System, so I used the function:

mam2sug( . ).

Then, I had to change some things about my fis file, because Anfis doesnt accept all fis file .

After this, I loaded my fis file in Anfis, loaded my Data and clicked on train.

My problem is that the training doesn't work, the performance doesnt improve.

Is it normal? I dont think. Or Have i made some mistakes ?

This is the results: * ANFIS info: * Number of nodes: 40 * Number of linear parameters: 24 * Number of nonlinear parameters: 44 * Total number of parameters: 68 * Number of training data pairs: 1313 * Number of checking data pairs: 0 * Number of fuzzy rules: 4

Start training ANFIS ...

Please help me. I have similar kind of problem. Actually I need a mamdani system as I want to build the rule base myself. However, I want to train the system. But not getting any suitable command. Converting my mamdani system to sugeno type using mam2sug() does not help.

Please reply asap!!!
