Divide targets into three sets using blocks of indices
[trainInd,valInd,testInd] = divideblock(Q,trainRatio,valRatio,testRatio)
[trainInd,valInd,testInd] = divideblock(Q,trainRatio,valRatio,testRatio) separates targets into three sets: training, validation, and testing. It takes the following inputs:
Number of targets to divide up.
Ratio of targets for training. Default = 0.7.
Ratio of targets for validation. Default = 0.15.
Ratio of targets for testing. Default = 0.15.
Here are the network properties that define which data division function to use, what its parameters are, and what aspects of targets are divided up, when train is called.
