Fuzzy system tuning with the Simplex method fis=Simplex(fis,InTrain,OutTrain,params,options,etTuningInfo,axPIDiagram,axOutputDataDiagram) Fuzzy system tuning using the Simplex method and creation of new rules. It works with MISO systems and trapezoid shaped linguistic terms ('trapmf'). ------------------------------------------------------------------------- Parameters ------------------------------------------------------------------------- fis - complex structure describing the fuzzy inference system InTrain - N by M matrix containing the input data, where N is number of data points and M is the number of input dimensions OutTrain - N by 1 matrix containing the output data, where N is number of data points and 1 is the number of output dimensions params - parameters of the fuzzy inference |-InterpolationType |-RPtype |-... options - Options of the system tuning options(1) Number of allowed decimals options(2) Coefficient for the step options(3) -- not used options(4) Maximum number of system evaluations options(5) Info display during calculations options(6) Save FIS and info after each system evaluation options(7) -- not used options(8) -- not used options(9) -- not used options(10) -- not used options(11) Plot Performance Index options(12) Plot original and calculated data options(13) - Tuning method type 1 - RBE-DSS 2 - RBE-SI 3 - ACP 4 - Simplex options(14) - Performance index type 1 - MSE 2 - RMSE 3 - RMSEP 4 - R 5 - RR 6 - AD 7 - ADP 8 - SKL 9 - JDD Jensen Difference Divergence options(15) - Stop the tuning when the performance index falls below this value options(16) - Core width in percentage of the range options(17) - Support width in percentage of the range options(18) - Parameterization type 1 - breakpoints 2 - relative distances 3 - conserving Ruspini partition 4 - reference point options(19) - Minimum value for the step coefficient (Simplex method) etTuningInfo - handle of the editbox displaying the tuning preferences axPIDiagram - handles of the axes PI axOutputDataDiagram - handles of the OutputDataDiagram ------------------------------------------------------------------------- Returned values ------------------------------------------------------------------------- fis - complex structure describing the fuzzy inference system ------------------------------------------------------------------------- Remarks ------------------------------------------------------------------------- The centre of the core is is used as reference point. ------------------------------------------------------------------------- Zsolt Csaba Johanyák, johanyak.csaba@gamf.kefo.hu, v. 1.0, 22 Oct 2008
