Top Trees — The Top Tree is a binary tree based data structure for unrooted dynamic trees which is used mainly for carrying out various path related operations, it allows simple Divide and conquer algorithms. It has since been augmented to maintain… … Wikipedia
Pruning (decision trees) — Pruning is a technique in machine learning that reduces the size of decision trees by removing sections of the tree that provide little power to classify instances. The dual goal of pruning is reduced complexity of the final classifier as well as … Wikipedia
B-tree — In computer science, a B tree is a tree data structure that keeps data sorted and allows searches, insertions, and deletions in logarithmic amortized time. It is most commonly used in databases and filesystems. In B trees, internal (non leaf)… … Wikipedia
Radix tree — In computer science, a radix tree (also patricia trie or radix trie) is a space optimized trie data structure where each node with only one child is merged with its child. The result is that every internal node has at least two children. Unlike… … Wikipedia
Game tree — If you re looking for game tree as it s used in game theory (not combinatorial game theory), please see Extensive form game. In game theory, a game tree is a directed graph whose nodes are positions in a game and whose edges are moves. The… … Wikipedia
Tree-adjoining grammar — (TAG) is a grammar formalism defined by Aravind Joshi. Tree adjoining grammars are somewhat similar to context free grammars, but the elementary unit of rewriting is the tree rather than the symbol. Whereas context free grammars have rules for… … Wikipedia
Tree (graph theory) — Trees A labeled tree with 6 vertices and 5 edges Vertices v Edges v 1 Chromatic number … Wikipedia
Binary tree — Not to be confused with B tree. A simple binary tree of size 9 and height 3, with a root node whose value is 2. The above tree is unbalanced and not sorted. In computer science, a binary tree is a tree data structure in which each node has at… … Wikipedia
Red-black tree — A red black tree is a type of self balancing binary search tree, a data structure used in computer science, typically used to implement associative arrays. The original structure was invented in 1972 by Rudolf Bayer who called them symmetric… … Wikipedia
Hilbert R-tree — Hilbert R tree, an R tree variant, is an index for multidimensional objects like lines, regions, 3 D objects, or high dimensional feature based parametric objects. It can be thought of as an extension to B+ tree for multidimensional objects.The… … Wikipedia
Implicit kd-tree — An implicit k d tree is a k d tree defined implicitly above a rectilinear grid. Its splitting planes positions and orientations are not given explicitly but implicitly by some recursive splitting function defined on the hyperrectangles belonging… … Wikipedia
