  2. Decision tree pruning - Wikipedia

    en.wikipedia.org/wiki/Decision_tree_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). Pre-pruning methods are considered to be more efficient because they do not induce an entire set, but rather trees remain small from the start.

  3. Economic methodology - Wikipedia

    en.wikipedia.org/wiki/Economic_methodology

    Economic methodology is the study of methods, especially the scientific method, in relation to economics, including principles underlying economic reasoning. [1] In contemporary English, 'methodology' may reference theoretical or systematic aspects of a method (or several methods).

  4. Silviculture - Wikipedia

    en.wikipedia.org/wiki/Silviculture

    There are two types of pruning: natural or self-pruning and artificial pruning. Most cases of self-pruning happen when branches do not receive enough sunlight and die. Wind can also take part in natural pruning which can break branches. [105] Artificial pruning is where people are paid to come and cut the branches.

  5. Pruning - Wikipedia

    en.wikipedia.org/wiki/Pruning

    A reduction cut may be performed while still allowing about 50% of the branch. This is done to help maintain form and deter the formation of co-dominant leaders. Temporary branches may be too large for a removal cut so subordination pruning should be done to slowly reduce a limb by 50% each year to allow the tree to properly heal from the cut.

  6. Branch collar - Wikipedia

    en.wikipedia.org/wiki/Branch_collar

    The traditional method of pruning branches was to make an even level cut against the tree trunk, but this technique is currently avoided as evidence has shown that flush cuts increase the wound size and encourage the invasion of the wound by microorganisms and decay. [17] Therefore, the current recommendation encourages that branches should be ...

  7. Alpha–beta pruning - Wikipedia

    en.wikipedia.org/wiki/Alpha–beta_pruning

    Alpha–beta pruning is a search algorithm that seeks to decrease the number of nodes that are evaluated by the minimax algorithm in its search tree. It is an adversarial search algorithm used commonly for machine playing of two-player combinatorial games ( Tic-tac-toe , Chess , Connect 4 , etc.).

  8. Microeconomics - Wikipedia

    en.wikipedia.org/wiki/Microeconomics

    Information economics is a branch of microeconomic theory that studies how information and information systems affect an economy and economic decisions. Information has special characteristics. It is easy to create but hard to trust. It is easy to spread but hard to control. It influences many decisions.
