divideind

Purpose

Divide vectors into three sets using specified indices

Syntax

• [trainV,valV,testV,trainInd,valInd,testInd] = 
  divideind(allV,trainInd,valInd,testInd)
  

Description

divideind is used to separate input and target vectors into three sets: training, validation, and testing. It takes the following inputs,

allV	R x Q matrix of Q R-element vectors
trainInd	Training indices
valInd	Validation indices
testInd	Test indices

and returns

trainV	Training vectors
valV	Validation vectors
testV	Test vectors
trainInd	Training indices (unchanged)
valInd	Validation indices (unchanged)
testInd	Test indices (unchanged)

Examples

• p = rands(3,1000);
  trainInd = [(1:100) (301:800)];
  valInd = [(101:200) (801:900)];
  testInd = [(201:300) (901:1000)];
  [trainP,valP,testV] = divideind(p,trainInd,valInd,testInd);
  

Network Use

Here are the network properties that define which data division function to use, and what its parameters are, when train is called.
