In False Positive results the DT is appearing to be performing better than RF. While in False Negative results the RF is appearing to be performing better than DT

Hi,
Hope your are doing well,Have used Classification algorithms decision tree (j48) and Random forest algorithm for training and testing data, after training and testing of the data set got end results in which False Positive results the DT is appearing to be performing better than RF. While in False Negative results the RF is appearing to be performing better than DT
waiting for your positive and quick response.
