  2. Row- and column-major order - Wikipedia

    en.wikipedia.org/wiki/Row-_and_column-major_order

    To use column-major order in a row-major environment, or vice versa, for whatever reason, one workaround is to assign non-conventional roles to the indexes (using the first index for the column and the second index for the row), and another is to bypass language syntax by explicitly computing positions in a one-dimensional array.

  3. UpSet plot - Wikipedia

    en.wikipedia.org/wiki/UpSet_plot

    As sets vary in size, the size of the set is plotted as bar charts on top of the columns. The size of the intersections are shown aligned with the rows, also as bar charts. This layout facilitates the comparison between the sizes of individual intersections, as the size of the bars is easy to compare. UpSets can be used horizontally and vertically.

  4. Low-rank matrix approximations - Wikipedia

    en.wikipedia.org/wiki/Low-rank_matrix_approximations

    Low-rank matrix approximations are essential tools in the application of kernel methods to large-scale learning problems. [1]Kernel methods (for instance, support vector machines or Gaussian processes [2]) project data points into a high-dimensional or infinite-dimensional feature space and find the optimal splitting hyperplane.

  5. Help:Advanced table formatting - Wikipedia

    en.wikipedia.org/wiki/Help:Advanced_table_formatting

    For each table, insert an alpha-prefix on each column (making each row-token "|-" to sort as column zero, like prefix "Row124col00"), then sort into a new file, and then de-prefix the column entries. Again, bear in mind, the tedious hand-editing of items in each row is often faster than the potential delay of automated edits gone awry.

  6. Hadamard's inequality - Wikipedia

    en.wikipedia.org/wiki/Hadamard's_inequality

    In mathematics, Hadamard's inequality (also known as Hadamard's theorem on determinants [1]) is a result first published by Jacques Hadamard in 1893. [2] It is a bound on the determinant of a matrix whose entries are complex numbers in terms of the lengths of its column vectors.

  7. Bar chart - Wikipedia

    en.wikipedia.org/wiki/Bar_chart

    The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes called a column chart and has been identified as the prototype of charts. [1] A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared, and the other axis represents a measured value.

  8. Effect size - Wikipedia

    en.wikipedia.org/wiki/Effect_size

    In statistics, an effect size is a value measuring the strength of the relationship between two variables in a population, or a sample-based estimate of that quantity. It can refer to the value of a statistic calculated from a sample of data, the value of one parameter for a hypothetical population, or to the equation that operationalizes how statistics or parameters lead to the effect size ...

  9. Seasonal subseries plot - Wikipedia

    en.wikipedia.org/wiki/Seasonal_subseries_plot

    Seasonal sub-series plots are formed by [3]. Vertical axis: response variable Horizontal axis: time of year; for example, with monthly data, all the January values are plotted (in chronological order), then all the February values, and so on.
