  2. Statistical region merging - Wikipedia

    en.wikipedia.org/wiki/Statistical_Region_Merging

    [1] [2] The algorithm is used to evaluate the values within a regional span and grouped together based on the merging criteria, resulting in a smaller list. Some useful examples are creating a group of generations within a population , or in image processing , grouping a number of neighboring pixels based on their shades that fall within a ...

  3. VIKOR method - Wikipedia

    en.wikipedia.org/wiki/VIKOR_method

    The Fuzzy VIKOR method has been developed to solve problem in a fuzzy environment where both criteria and weights could be fuzzy sets. The triangular fuzzy numbers are used to handle imprecise numerical quantities. Fuzzy VIKOR is based on the aggregating fuzzy merit that represents distance of an alternative to the ideal solution.

  4. Selection sort - Wikipedia

    en.wikipedia.org/wiki/Selection_sort

    Selection sort can also be used on list structures that make add and remove efficient, such as a linked list. In this case it is more common to remove the minimum element from the remainder of the list, and then insert it at the end of the values sorted so far. For example:

  5. Decision tree pruning - Wikipedia

    en.wikipedia.org/wiki/Decision_tree_pruning

    Pruning processes can be divided into two types (pre- and post-pruning). Pre-pruning procedures prevent a complete induction of the training set by replacing a stop criterion in the induction algorithm (e.g. max. Tree depth or information gain (Attr)> minGain).

  6. Davies–Bouldin index - Wikipedia

    en.wikipedia.org/wiki/Davies–Bouldin_index

    The starting point for this new version of the validation index is the result of a given soft clustering algorithm (e.g. fuzzy c-means), shaped with the computed clustering partitions and membership values associating the elements with the clusters. In the soft domain, each element of the system belongs to every classes, given the membership ...

  7. Weighted sum model - Wikipedia

    en.wikipedia.org/wiki/Weighted_Sum_Model

    The choice of values for the weights is rarely easy. The simple default of equal weighting is sometimes used when all criteria are measured in the same units. Scoring methods may be used for rankings (universities, countries, consumer products etc.), and the weights will determine the order in which these entities are placed.

  8. Skip list - Wikipedia

    en.wikipedia.org/wiki/Skip_list

    To index the skip list and find the i'th value, traverse the skip list while counting down the widths of each traversed link. Descend a level whenever the upcoming width would be too large. For example, to find the node in the fifth position (Node 5), traverse a link of width 1 at the top level.

  9. Grid (spatial index) - Wikipedia

    en.wikipedia.org/wiki/Grid_(spatial_index)

    A grid-based spatial index has the advantage that the structure of the index can be created first, and data added on an ongoing basis without requiring any change to the index structure; indeed, if a common grid is used by disparate data collecting and indexing activities, such indices can easily be merged from a variety of sources.
