Random Forest is a supervised machine learning algorithm. From the name itself we are able to know that, the Random Fores! technique produces multiple decision trees before giving an output. This technique is based on the thing that more number of tree: would tend to the right decision. For classification, it uses a voting system and then decides the class whereas in regression it take:  the mean of all the outputs of the decision trees. It works well with large datasets with high dimensionality [15]. Random forest algorithm steps
