# Do classification trees need to consider the correlation between attributes?

In decision tree classification, we use the attribute that splits records, like entropy, as split nodes.

Does it need to consider the correlation between attributes?

• Usually, the algorithms used will automatically take into accoiunt any feature correlations. – kjetil b halvorsen Feb 13 '15 at 18:53
• We know that Bayes classifier must use the independent attributes as input. Does Decision tree have the restrictions? – WeiYuan Feb 14 '15 at 1:12
• In addition, if we use dependent attributes in decision tree classification, the algorithm will automatically handle it? Can the entropy consider the correlation between attributes? – WeiYuan Feb 14 '15 at 1:14
