  3. Mode (statistics) - Wikipedia

    en.wikipedia.org/wiki/Mode_(statistics)

    In statistics, the mode is the value that appears most often in a set of data values. [1] If X is a discrete random variable, the mode is the value x at which the probability mass function takes its maximum value (i.e., x=argmax x i P(X = x i)). In other words, it is the value that is most likely to be sampled.

  4. Correlation function (astronomy) - Wikipedia

    en.wikipedia.org/wiki/Correlation_function...

    By default, "correlation function" refers to the two-point autocorrelation function. The two-point autocorrelation function is a function of one variable (distance); it describes the excess probability of finding two galaxies separated by this distance (excess over and above the probability that would arise if the galaxies were simply scattered ...

  5. Cosine similarity - Wikipedia

    en.wikipedia.org/wiki/Cosine_similarity

    The normalized angle, referred to as angular distance, between any two vectors and is a formal distance metric and can be calculated from the cosine similarity. [5] The complement of the angular distance metric can then be used to define angular similarity function bounded between 0 and 1, inclusive.

  6. Cardinality of the continuum - Wikipedia

    en.wikipedia.org/wiki/Cardinality_of_the_continuum

    Cantor defined cardinality in terms of bijective functions: two sets have the same cardinality if, and only if, there exists a bijective function between them. Between any two real numbers a < b, no matter how close they are to each other, there are always infinitely many other real numbers, and Cantor showed that they are as many as those ...

  7. Hausdorff distance - Wikipedia

    en.wikipedia.org/wiki/Hausdorff_distance

    The definition of the Hausdorff distance can be derived by a series of natural extensions of the distance function (,) in the underlying metric space M, as follows: [7] Define a distance function between any point x of M and any non-empty set Y of M by: (,) = {(,)}.

  8. Exchange value - Wikipedia

    Third, value is not the same thing as exchange-value (or price). Rather, the value is the shared characteristic of the exchange-values of all the commodities. He calls this the "common factor", whereas someone else might call it the "essence". In contrast, the exchange-value represents the appearance or "form" of expression of value in trade.

    Count Carl Gustaf Mannerheim (1797–1854), the governor of the Vyborg Province, entomologist and the grandfather of Baron C. G. E. Mannerheim. Count (feminine: countess) is a historical title of nobility in certain European countries, varying in relative status, generally of middling rank in the hierarchy of nobility. [1]
