  2. Approximate string matching - Wikipedia

    en.wikipedia.org/wiki/Approximate_string_matching

    Different approximate matchers impose different constraints. Some matchers use a single global unweighted cost, that is, the total number of primitive operations necessary to convert the match to the pattern. For example, if the pattern is coil, foil differs by one substitution, coils by one insertion, oil by one deletion, and foal by two ...

  3. Regular expression - Wikipedia

    en.wikipedia.org/wiki/Regular_expression

    A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. Usually such patterns are used by string-searching algorithms for "find" or "find and replace" operations on strings , or for input validation .

  4. Matching (statistics) - Wikipedia

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

    Matching is a statistical technique that evaluates the effect of a treatment by comparing the treated and the non-treated units in an observational study or quasi-experiment (i.e. when the treatment is not randomly assigned).

  5. Match-to-sample task - Wikipedia

    en.wikipedia.org/wiki/Match-to-sample_task

    The match-to-sample task has been shown to be an effective tool to understand the impact of sleep deprivation on short-term memory. One research study [9] compared performance on a traditional sequential test battery with that on a synthetic work task requiring subjects to work concurrently on several tasks, testing subjects every three hours during 64 hrs of sleep deprivation.

  6. Hash table - Wikipedia

    en.wikipedia.org/wiki/Hash_table

    A hash table uses a hash function to compute an index, also called a hash code, into an array of buckets or slots, from which the desired value can be found. During lookup, the key is hashed and the resulting hash indicates where the corresponding value is stored. A map implemented by a hash table is called a hash map.

  7. Bracket matching - Wikipedia

    en.wikipedia.org/wiki/Bracket_matching

    Vim's % command does bracket matching, [1] and NetBeans has bracket matching built-in. [2] Bracket matching can also be a tool for code navigation. In Visual Studio [3] C++ 6.0, bracket matching behavior was set to ignore brackets found in comments.

  8. Match moving - Wikipedia

    en.wikipedia.org/wiki/Match_moving

    3-D reconstruction is the interactive process of recreating a photographed object using tracking data. This technique is related to photogrammetry . In this particular case we are referring to using match moving software to reconstruct a scene from incidental footage.

  9. Matched filter - Wikipedia

    en.wikipedia.org/wiki/Matched_filter

    [1] [2] This is equivalent to convolving the unknown signal with a conjugated time-reversed version of the template. The matched filter is the optimal linear filter for maximizing the signal-to-noise ratio (SNR) in the presence of additive stochastic noise .
