Decision trees normally suffer from the problem of overfitting if it’s allowed to grow without any control. 1. Random forests are created from subsets of data, and the final output is based on average or majority ranking; hence the problem of overfitting is taken care of. 2. A single decision tree is faster in computation. 2.

"WebRandom forests can be set up without the target variable. Using this feature, we will calculate the proximity matrix and use the OOB proximity values. Since the proximity matrix gives us a measure of closeness between the observations, it can be converted into clusters using hierarchical clustering methods. " - Hierarchical random forest
