Hey!

I recently started using MATLAB and more specifically, the Statistics and Machine Learning toolbox. When choosing the Classification Learner, I can choose my Validation Scheme - when choosing Cross Validation, does MATLAB shuffle my data? Couldn't find any information about this in the docs :(

Kind regards

Dennis

Hi Dennis,

Yes, while applying cross-validation, the data will be suffled. The "cvpartition"/"crossval" functions define a random partition on the data set. Please refer to the following links capuring more information on this:

You can check out the link below to know more about cross validation in MATLAB: Cross-Validation - MATLAB & Simulink (mathworks.com)

I hope this information helps!
