How to partition data in cells for validation in machine learning model?
Hello there , I have training data for 4 trials stores in a 4×1 cell named "trainingdataX" and "trainingdataY" as whoen here and I am trying to pull out 15 percent of all this data for validation purposes and store it in variables "Xval" and "Yval". How would I be able to do this if the data is stored in a cells corresponding to the trials and ensure the corresponding value is partioned out for validation too? Any help is greatly appreciated!
%Exclude Data for Val
rng(‘default’)
n = %im not sure what to put here to have it pull data from each of the 4 trials
partition = cvpartition(n,’Holdout’,0.15);
idxTrain = training(partition);
FinalTrainX = trainingdataX(idxTrain,:)
FinalTrainY = trainingdataY(idxTrain,:)
idxNew = test(partition);
Xval = trainingdataX(idxNew,:)
Yval = trainingdataY(idxNew,:)Hello there , I have training data for 4 trials stores in a 4×1 cell named "trainingdataX" and "trainingdataY" as whoen here and I am trying to pull out 15 percent of all this data for validation purposes and store it in variables "Xval" and "Yval".
