1 week ago Random forests is considered as a highly accurate and robust method because of the number of decision trees participating in the process.It does not suffer from the overfitting problem. The main reason is that it takes the average of all the predictions, which cancels out the biases.The algorithm can be used in both classification and regression problems.
