WebUnderstanding the decision tree structure. ¶. The decision tree structure can be analysed to gain further insight on the relation between the features and the target to predict. In this example, we show how to retrieve: the nodes that were reached by a sample using the decision_path method; the decision path shared by a group of samples. WebJun 2, 2016 · By the way, 90%, if not overfitted, is great result, may be you even don't need to improve it. You could look into pruning the leaves to improve the generalization of the decision tree. But as was mentioned, 90% accuracy can be considered quite good.. 90% is good or bad, depends on the domain of the data.

WebA decision tree is a predictive model, which uses a tree-like graph to map the observed data of an object to conclusions about the target value of this object. The decision tree is known as a classification tree if the target variable takes a finite set of values, whereas it is referred to as a regression tree if the target variable is continuous.
