Inference in bayesian networks with recursive probability trees: data structure definition and operations. International Journal of Intelligent Systems, 28(7):623-647, 2013.Cano, A., Gómez-Olmedo, M., Moral, S., Pérez-Ariza, C., Salmerón, A.: Inference in Bayesian networks with recursive ...
The B-tree is a generalization of a binary search tree in that a node can have more than two children. According to Knuth's definition, a B-tree of order m is a tree which satisfies the following properties: Every node has at most m children. Every non-leaf node (except root) has ...
The above definition of Uno’s C-statistic was intended for continuous models, and (18) may be very unstable in small trees due to the large number of observations with tied risks which are not counted in either the numerator or denominator. To avoid this, we include these pairs of observa...
The decisiontree(DT) is currently among the most popularclassification algorithmsindata miningand machine learning. A DT is a classifier with the structure of a tree, where each node is a leaf indicating a class, or an internal decision node that specifies some test to be carried out on a ...
This idea is also used in C-fuzzy decision trees and Cluster–context fuzzy decision trees, which take part in C-fuzzy random forest, by definition. These trees are designed the way they have several growth stop criteria: All nodes achieve higher heterogeneity than assumed boundary value, ...
Trajectory conservation was originally defined in the literature16, and in this work we adapt the definition to our case where the tree structure should be explicitly considered to compute pseudotime. Precisely, for each single lineage that forms the aligned trajectory tree, a series of simulation ...

is by definition a tree. While dependence trees are indeed also suitable for time-courses, the complex dependency structures necessary due to branching of the developmental tree into distinct lineages prevents the use of time-course models, as there is no effective way of incorporating the necessary...
Our leaf label specification follows standard definition line (defline) format, as can be seen from the examples in Table 2, so that trees automatically generated from sequences found in databases like the NR (non-redundant) database [9] can be processed easily. Our parser uses regular expres...
Equation 6-3 shows the definition of the entropy of theithnode. for example,the depth-2 left node in Figure 6-1 has an entropy equal to . so should you use Gini impurity or entropy?the truth is,most of the time it doesn't make a big difference: they lead to similar trees.Gini im...
