The classification starts with the root node
and proceeds to the leaves that are most related to the response variable.
The node at the topmost of the decision tree visual diagram is the root node
3, the tree structure is organized for routing, as a sink node becomes a root node
In the case of DG trees, the leaf nodes merely sense the data and transmit them to an upstream intermediate node that would in turn aggregate its own data with data received from all of its child nodes and forward the aggregated data to an upstream node that is on the path to the root node
of the DG tree.
A CART tree is a binary decision tree that node is splitting into two child nodes repeatedly, beginning with the root node
that contains the whole learning sample .
The tree induction begins with a root node
that represents the entire dataset, given dataset and recursively split the data into a few subsets by testing for a given attribute at each level of the node.
market as root node
when researching the dependence of main stock market indexes (Jiang, 2013).
After the update, the each label represents the root node
in the equivalence tree it belongs to as shown in Fig.
The second approach deals with energy efficient root node
selection  and cluster formation method ,  presented in sections B and C respectively.
The root node
, where finally our function of measurements has to be computed, will be denoted by r (located at [V.
V = A [union] C [union] N [union] [tau] is the finite set of nodes with action nodes A, condition nodes C, control flow nodes N, and a root node
Node 0, which is called the root node
, contains descriptive statistics related to the prevalence of abortion.
