Decision Tree Important Hyper parameters


  • Optimization Criteria : Gini impurity or Entropy/Info gain
  • Max Depth - Build trees with max. d depth deep; d = Number of nodes from top
  • min_samples_split: The minimum number of samples required to split an internal node
  • min_samples_leaf: The minimum number of samples required to be at a leaf node
  • max_features: The number of features to consider when looking for the best split
  • min_impurity_decrease: A node will be split if this split induces a decrease of the impurity greater than or equal to this value
  • class_weight:Weights associated with classes in the form {class_label: weight}
