i am doing face recogntion using anfis. i already train the network but its doesnt follow the target.I already put 1000 epoch and 20 mf to train the network but still not to target. my code is:
input=[trainData(:)];
data=[input target];
init_fis = genfis1(data);
anfis_net1=anfis(data,20, [1000,0,0.01,1.1,1.1],[1,1,1,1]);
anfis_eval1=evalfis(input,anfis_net1);
comp1=[target anfis_eval1]
input and target that i got are:
comp1=
1.0000 0.2379
0 -0.1536
0 0.3950
0 0.2237
0 0.3400
0 0.2628
1.0000 0.3671
0 0.5821
0 0.3832
0 0.4688
0 0.3510
0 0.2667
1.0000 0.2301
0 -0.1526
0 0.3949

1.0000 0.3208
0 0.6746
0 0.4190
0 0.6348
0 0.5834
0 0.2862
1.0000 0.2605
0 0.4826
0 0.4048
0 0.2038
0 0.4601
0 0.2187
There are 840 input and just some of it is nearer with the target. But when I put the target 1.000, all predicted value is equal to the target. Parameters that can be change are mf and epoch only. I already try until 3000 epoch but still not the same with the target. Can somebody suggest to me what should I do.

My dear I think you can try the following:
1. Triangular MF;
2. Zero order Sugeno model instead of first order Sugeno;
3. initial step-size;
4. step-size decrease rate;
5. step-size increase rate;
Hope this will help you
