Algorithm 2: Model Learning Algorithm.

Require: data D Ensure: model M     Transform the labels of each row of the data into a list L     Convert the answers to the questions into integers I     Split the data D into training $D_{\mathrm{train}}$ and test sets $D_{\mathrm{train}}$     Train a Multi-Output Classifier $MOC$ using a RandomForestClassifier $RFC$ with $D_{\mathrm{train}}$ as input     Set the number of estimators in $RFC$ to 10     return $M=MOC(RFC,n_{\mathrm{estimators}}=10)$
