  2. Wide and narrow data - Wikipedia

    en.wikipedia.org/wiki/Wide_and_narrow_data

    The pandas package in Python implements this operation as "melt" function which converts a wide table to a narrow one. The process of converting a narrow table to wide table is generally referred to as "pivoting" in the context of data transformations.

  3. Comma-separated values - Wikipedia

    en.wikipedia.org/wiki/Comma-separated_values

    Comma-separated values (CSV) is a text file format that uses commas to separate values, and newlines to separate records. A CSV file stores tabular data (numbers and text) in plain text, where each line of the file typically represents one data record. Each record consists of the same number of fields, and these are separated by commas in the ...

    To force initial column widths to specific requirements, rather than accepting the width of the widest text element in a column's cells, follow this example. Note that wrap-around of text is forced for columns where the width requires it. Do not use min-width:Xpx;

  5. Comparison of programming languages (string functions)

    en.wikipedia.org/wiki/Comparison_of_programming...

    String functions are used in computer programming languages to manipulate a string or query information about a string (some do both).. Most programming languages that have a string datatype will have some string functions although there may be other low-level ways within each language to handle strings directly.

  7. B-tree - Wikipedia

    en.wikipedia.org/wiki/B-tree

    To maintain the predefined range of child nodes, internal nodes may be joined or split. Usually, the number of keys is chosen to vary between d {\displaystyle d} and 2 d {\displaystyle 2d} , where d {\displaystyle d} is the minimum number of keys, and d + 1 {\displaystyle d+1} is the minimum degree or branching factor of the tree.

  8. Isolation forest - Wikipedia

    en.wikipedia.org/wiki/Isolation_forest

    SCiForest (Isolation Forest with Split-selection Criterion) is an extension of the original Isolation Forest algorithm, specifically designed to target clustered anomalies. It introduces a split-selection criterion and uses random hyper-planes that are non-axis-parallel to the original attributes.

  9. k-means clustering - Wikipedia

    en.wikipedia.org/wiki/K-means_clustering

    k-means clustering is a method of vector quantization, originally from signal processing, that aims to partition n observations into k clusters in which each observation belongs to the cluster with the nearest mean (cluster centers or cluster centroid), serving as a prototype of the cluster.
