  2. Canberra distance - Wikipedia

    en.wikipedia.org/wiki/Canberra_distance

    The Canberra distance is a numerical measure of the distance between pairs of points in a vector space, introduced in 1966 [1] and refined in 1967 [2] by Godfrey N. Lance and William T. Williams. It is a weighted version of L ₁ (Manhattan) distance . [ 3 ]

  3. Normalized compression distance - Wikipedia

    en.wikipedia.org/.../Normalized_compression_distance

    The normalized compression distance has been used to fully automatically reconstruct language and phylogenetic trees. [2] [3] It can also be used for new applications of general clustering and classification of natural data in arbitrary domains, [3] for clustering of heterogeneous data, [3] and for anomaly detection across domains. [5]

  4. Gower's distance - Wikipedia

    en.wikipedia.org/wiki/Gower's_distance

    In statistics, Gower's distance between two mixed-type objects is a similarity measure that can handle different types of data within the same dataset and is particularly useful in cluster analysis or other multivariate statistical techniques. Data can be binary, ordinal, or continuous variables.

  5. Statistical distance - Wikipedia

    en.wikipedia.org/wiki/Statistical_distance

    A distance between populations can be interpreted as measuring the distance between two probability distributions and hence they are essentially measures of distances between probability measures. Where statistical distance measures relate to the differences between random variables, these may have statistical dependence, [1] and hence these ...

  6. Distance - Wikipedia

    en.wikipedia.org/wiki/Distance

    A metric or distance function is a function d which takes pairs of points or objects to real numbers and satisfies the following rules: The distance between an object and itself is always zero. The distance between distinct objects is always positive. Distance is symmetric: the distance from x to y is always the same as the distance from y to x.

  7. Similarity measure - Wikipedia

    en.wikipedia.org/wiki/Similarity_measure

    An image distance measure compares the similarity of two images in various dimensions such as color, texture, shape, and others. For example, a distance of 0 signifies an exact match with the query, with respect to the dimensions that were considered. As one may intuitively gather, a value greater than 0 indicates various degrees of ...

  8. Minkowski distance - Wikipedia

    en.wikipedia.org/wiki/Minkowski_distance

    The Minkowski distance or Minkowski metric is a metric in a normed vector space which can be considered as a generalization of both the Euclidean distance and the Manhattan distance. It is named after the Polish mathematician Hermann Minkowski .

  9. Bregman divergence - Wikipedia

    en.wikipedia.org/wiki/Bregman_divergence

    The submodular Bregman divergences subsume a number of discrete distance measures, like the Hamming distance, precision and recall, mutual information and some other set based distance measures (see Iyer & Bilmes, 2012 for more details and properties of the submodular Bregman.) For a list of common matrix Bregman divergences, see Table 15.1 in. [8]
