Hi Zeynab,

After importing the data to be trained Naive Bayes Classifier can be found by clicking on the down arrow button right of the Fine Tree button option. See the attached images.

"training" is used to train a classifier (pass it to FIT method), and "sample" is used to test the classifier performance on data not used for training (pass it to PREDICT method). for example:

O1 = NaiveBayes.fit(training,group);
C1 = O1.predict(sample);
cMat1 = confusionmat(sampleGroup,C1);

where sampleGroup is an array of true class labels for the predictor matrix in "sample".

MATLAB: Random Forest using Classification Learner App

Hi,

I was able to find this information from the MathWorks documentation: To explore classification ensembles interactively, use the Classification Learner app. For greater flexibility, use fitcensemble in the command-line interface to boost or bag classification trees, or to grow a random forest:

Based on the above, the Random Forest Learner functionality may not be part of the Classification Learner App.
