Decision tree machine learning.
Decision Tree # A decision tree grows from a root representing a YES/NO condition. The root branches into two child nodes for two different states. We travel from the root to its left child node when the condition is true or otherwise to its right child. Each child node could be a leaf (also called terminal node) or the root of a subtree. For the latter case, we …

Decision trees (DTs) epitomize what have become to be known as interpretable machine learning (ML) models. This is informally motivated by paths in DTs being often much smaller than the total number of features. This paper shows that in some settings DTs can hardly be deemed interpretable, with paths in a DT being arbitrarily …A single Decision Tree by itself has subpar accuracy, when compared to other machine learning algorithms. One tree alone typically doesn’t generate the best predictions, but the tree structure makes it easy to control the bias-variance trade-off. A single Decision Tree is not powerful enough, but an entire forest is!Introduction. Pruning is a technique in machine learning that involves diminishing the size of a prepared model by eliminating some of its parameters.
