  2. Data transformation (statistics) - Wikipedia

    en.wikipedia.org/wiki/Data_transformation...

    Data transformation (statistics) A scatterplot in which the areas of the sovereign states and dependent territories in the world are plotted on the vertical axis against their populations on the horizontal axis. The upper plot uses raw data. In the lower plot, both the area and population data have been transformed using the logarithm function.

  3. Lineweaver–Burk plot - Wikipedia

    en.wikipedia.org/wiki/Lineweaver–Burk_plot

    Definitions. The Lineweaver–Burk plot derives from a transformation of the Michaelis–Menten equation , in which the rate is a function of the substrate concentration and two parameters , the limiting rate, and , the Michaelis constant. Taking reciprocals of both sides of this equation it becomes as follows:

  4. Knowledge graph embedding - Wikipedia

    en.wikipedia.org/wiki/Knowledge_graph_embedding

    In representation learning, knowledge graph embedding ( KGE ), also referred to as knowledge representation learning ( KRL ), or multi-relation learning, [1] is a machine learning task of learning a low-dimensional representation of a knowledge graph 's entities and relations while preserving their semantic meaning.

  5. List of mathematical abbreviations - Wikipedia

    en.wikipedia.org/wiki/List_of_mathematical...

    a.e. – almost everywhere. AFSOC - Assume for the sake of contradiction. Ai – Airy function. AL – Action limit. Alt – alternating group (Alt ( n) is also written as A n.) A.M. – arithmetic mean. AP – arithmetic progression. arccos – inverse cosine function. arccosec – inverse cosecant function.

  6. Relationships among probability distributions - Wikipedia

    en.wikipedia.org/wiki/Relationships_among...

    The reciprocal 1/ X of a random variable X, is a member of the same family of distribution as X, in the following cases: Cauchy distribution, F distribution, log logistic distribution . Examples: If X is a Cauchy ( μ, σ) random variable, then 1/ X is a Cauchy ( μ / C, σ / C) random variable where C = μ2 + σ2.

  7. Multiplicative inverse - Wikipedia

    en.wikipedia.org/wiki/Multiplicative_inverse

    The graph forms a rectangular hyperbola. In mathematics, a multiplicative inverse or reciprocal for a number x, denoted by 1/ x or x−1, is a number which when multiplied by x yields the multiplicative identity, 1. The multiplicative inverse of a fraction a / b is b / a. For the multiplicative inverse of a real number, divide 1 by the number.

  8. Möbius transformation - Wikipedia

    en.wikipedia.org/wiki/Möbius_transformation

    Möbius transformations are defined on the extended complex plane ^ = {} (i.e., the complex plane augmented by the point at infinity).. Stereographic projection identifies ^ with a sphere, which is then called the Riemann sphere; alternatively, ^ can be thought of as the complex projective line.

  9. Brillouin zone - Wikipedia

    en.wikipedia.org/wiki/Brillouin_zone

    The first Brillouin zone is the locus of points in reciprocal space that are closer to the origin of the reciprocal lattice than they are to any other reciprocal lattice points (see the derivation of the Wigner–Seitz cell). Another definition is as the set of points in k -space that can be reached from the origin without crossing any Bragg plane.
