Foundations
In a decision tree, during inference, the route a particular example takes from the root to other conditions, terminating with a leaf. For example, in the following decision tree, the thicker arrows show the inference path for an example with the following feature values:
x = 7
y = 12
z = -3
The inference path in the following illustration travels through three conditions before reaching the leaf (Zeta).
The three thick arrows show the inference path.
See Decision trees in the Decision Forests course for more information.
