  2. Synaptic pruning - Wikipedia

    en.wikipedia.org/wiki/Synaptic_pruning

    Synaptic pruning, a phase in the development of the nervous system, is the process of synapse elimination that occurs between early childhood and the onset of puberty in many mammals, including humans. [1] Pruning starts near the time of birth and continues into the late-20s. [2]

  3. Pruning (artificial neural network) - Wikipedia

    en.wikipedia.org/wiki/Pruning_(artificial_neural...

    Pruning is the practice of removing parameters (which may entail removing individual parameters, or parameters in groups such as by neurons) from an existing artificial neural networks. [1] The goal of this process is to maintain accuracy of the network while increasing its efficiency .

  4. Pruning - Wikipedia

    en.wikipedia.org/wiki/Pruning

    Pruning is a horticultural, arboricultural, and silvicultural practice involving the selective removal of certain parts of a plant, such as branches, buds, or roots. The practice entails the targeted removal of diseased , damaged, dead, non-productive, structurally unsound, or otherwise unwanted plant material from crop and landscape plants .

  5. Synaptogenesis - Wikipedia

    en.wikipedia.org/wiki/Synaptogenesis

    Synaptogenesis is particularly important during an individual's critical period, during which there is a certain degree of synaptic pruning due to competition for neural growth factors by neurons and synapses. Processes that are not used, or inhibited during their critical period will fail to develop normally later on in life.

  6. Perceptual narrowing - Wikipedia

    en.wikipedia.org/wiki/Perceptual_narrowing

    Perceptual narrowing is a developmental process during which the brain uses environmental experiences to shape perceptual abilities. This process improves the perception of things that people experience often and causes them to experience a decline in the ability to perceive some things to which they are not often exposed.

  7. Mental age - Wikipedia

    en.wikipedia.org/wiki/Mental_age

    The changes in color from yellow/red to blue show the pruning process (source: NIMH). Mental age is a concept related to intelligence . It looks at how a specific individual, at a specific age, performs intellectually, compared to average intellectual performance for that individual's actual chronological age (i.e. time elapsed since birth).

  8. 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.

  9. Pruning (disambiguation) - Wikipedia

    en.wikipedia.org/wiki/Pruning_(disambiguation)

    Pruning is the practice of removing unwanted portions from a plant. Pruning may also refer to: Computer science. Decision tree pruning, a method of simplification ...
