  2. Active Directory - Wikipedia

    en.wikipedia.org/wiki/Active_Directory

    Active Directory ( AD) is a directory service developed by Microsoft for Windows domain networks. Windows Server operating systems include it as a set of processes and services. [1] [2] Originally, only centralized domain management used Active Directory. However, it ultimately became an umbrella title for various directory-based identity ...

  3. Directed acyclic graph - Wikipedia

    en.wikipedia.org/wiki/Directed_acyclic_graph

    Directed acyclic graph. In mathematics, particularly graph theory, and computer science, a directed acyclic graph ( DAG) is a directed graph with no directed cycles. That is, it consists of vertices and edges (also called arcs ), with each edge directed from one vertex to another, such that following those directions will never form a closed ...

  4. Forest plot - Wikipedia

    en.wikipedia.org/wiki/Forest_plot

    A forest plot, also known as a blobbogram, is a graphical display of estimated results from a number of scientific studies addressing the same question, along with the overall results. It was developed for use in medical research as a means of graphically representing a meta-analysis of the results of randomized controlled trials .

  5. Neural network (machine learning) - Wikipedia

    en.wikipedia.org/wiki/Neural_network_(machine...

    Neural network (machine learning) An artificial neural network is an interconnected group of nodes, inspired by a simplification of neurons in a brain. Here, each circular node represents an artificial neuron and an arrow represents a connection from the output of one artificial neuron to the input of another. Part of a series on.

  6. Steiner tree problem - Wikipedia

    en.wikipedia.org/wiki/Steiner_tree_problem

    The Steiner point S is located at the Fermat point of the triangle ABC. In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization. While Steiner tree problems may be formulated in a number of settings, they all ...

  7. Kruskal's algorithm - Wikipedia

    en.wikipedia.org/wiki/Kruskal's_algorithm

    Kruskal's algorithm [1] finds a minimum spanning forest of an undirected edge-weighted graph. If the graph is connected, it finds a minimum spanning tree. It is a greedy algorithm that in each step adds to the forest the lowest-weight edge that will not form a cycle. [2] The key steps of the algorithm are sorting and the use of a disjoint-set ...

  8. Random forest - Wikipedia

    en.wikipedia.org/wiki/Random_forest

    Random forests or random decision forests is an ensemble learning method for classification, regression and other tasks that operates by constructing a multitude of decision trees at training time. For classification tasks, the output of the random forest is the class selected by most trees. For regression tasks, the mean or average prediction ...

  9. Flexible single master operation - Wikipedia

    en.wikipedia.org/wiki/Flexible_single_master...

    Per-forest roles. These roles are unique at the forest level (both are located in the forest root domain): The Schema Master - The purpose of this role is to replicate schema changes to all other domain controllers in the forest. Since the schema of Active Directory is rarely changed, however, the Schema Master role will rarely do any work.
