Cross-validation (statistics) - Relationship To Other Forms of Validation

Relationship To Other Forms of Validation

In "true validation," or "holdout validation," a subset of observations is chosen randomly from the initial sample to form a validation or testing set, and the remaining observations are retained as the training data. Normally, less than a third of the initial sample is used for validation data. This would generally not be considered to be cross-validation since only a single partition of the data into training and testing sets is used.

Famous quotes containing the words relationship to, relationship and/or forms:

    Film music should have the same relationship to the film drama that somebody’s piano playing in my living room has to the book I am reading.
    Igor Stravinsky (1882–1971)

    When any relationship is characterized by difference, particularly a disparity in power, there remains a tendency to model it on the parent-child-relationship. Even protectiveness and benevolence toward the poor, toward minorities, and especially toward women have involved equating them with children.
    Mary Catherine Bateson (20th century)

    It is given to few to add the store of knowledge, to strike new springs of thought, or to shape new forms of beauty. But so sure as it is that men live not by bread, but by ideas, so sure is it that the future of the world lies in the hands of those who are able to carry the interpretation of nature a step further than their predecessors.
    Thomas Henry Huxley (1825–95)
