I am trying to optimize data which has many zeros in the training as well as the testing data set. I am optimizing it using ANN and ANFIS, but in both of them large errors occur. Is there any way to optimize such data?
to get the good result, data should not be repetitive. this problem often occurs with many zeros. better you can use MINITAB statistical tool to randomize data than import those data on ANN/ANFIS.
