The first step was to use the retrieve operator to load the input data, which was followed by select
attributes to select the required attributes. Furthermore, the set role operator was used to set our target
variable. After that cross-validation operator has been added to split the data into training and testing
data which will be further used in the process. Cross validation operator connects to a split screen
where we define our training and testing operators. The max depth for decision tree operator was set
to 5. After that apply model operator was used to apply the model. The last operator added was
performance operator which helped us evaluate the performance.
