Output FIS Structure for Checking Data
The output of the command line anfis, fismat2, is the output FIS structure
with the minimum checking error. This FIS structure is the one that you
should use for further calculation if checking data is used for cross validation.
Checking Error
The checking error is the difference between the checking data output value,
and the output of the fuzzy inference system corresponding to the same
checking data input value, which is the one associated with that checking
data output value. The checking error chkError records the RMSE for the
checking data at each epoch. fismat2 is the snapshot of the FIS structure
when the checking error is at its minimum. The ANFIS Editor GUI plots the
checking error versus epochs curve as the system is trained.
