  2. Random map - Wikipedia

    en.wikipedia.org/wiki/Random_map

    In video games, a random map is a map generated randomly by the computer, usually in strategy games. Random maps are often the core of single and multiplayer gameplay, aside from story based campaigns that are often shipped with the game. Each new game presents an unknown map, providing a new experience to the player, and an even playing field ...

    en.wikipedia.org/wiki/Random_matrix

    Random matrix theory (RMT) is the study of properties of random matrices, often as they become large. RMT provides techniques like mean-field theory , diagrammatic methods, the cavity method , or the replica method to compute quantities like traces , spectral densities , or scalar products between eigenvectors.

    There are two ways to embed the shape into an article, both using the {} template: Method 1: Using Wikidata. If the shape has a Wikidata item and the OpenStreetMap shape relation already has a wikidata tag set to that item's QID, you can embed a map of the shape directly onto a Wikipedia article as external data.

  5. List of chaotic maps - Wikipedia

    en.wikipedia.org/wiki/List_of_chaotic_maps

    In mathematics, a chaotic map is a map (an evolution function) that exhibits some sort of chaotic behavior. Maps may be parameterized by a discrete-time or a continuous-time parameter. Discrete maps usually take the form of iterated functions. Chaotic maps often occur in the study of dynamical systems . Chaotic maps and iterated functions often ...

  6. Random mapping - Wikipedia

    en.wikipedia.org/wiki/Random_mapping

    Random mapping. For data analysis, Random mapping (RM) is a fast dimensionality reduction method categorized as feature extraction method. The RM consists in generation of a random matrix that is multiplied by each original vector and result in a reduced vector. When the data vectors are high-dimensional it is computationally infeasible to use ...

    The waveform of 230 V and 50 Hz compared with 120 V and 60 Hz. The utility frequency, (power) line frequency (American English) or mains frequency (British English) is the nominal frequency of the oscillations of alternating current (AC) in a wide area synchronous grid transmitted from a power station to the end-user.
