Semi-supervised Learning in Human Cognition
Human responses to formal semi-supervised learning problems have yielded varying conclusions about the degree of influence of the unlabeled data (for a summary see ). More natural learning problems may also be viewed as instances of semi-supervised learning. Much of human concept learning involves a small amount of direct instruction (e.g. parental labeling of objects during childhood) combined with large amounts of unlabeled experience (e.g. observation of objects without naming or counting them, or at least without feedback).
Human infants are sensitive to the structure of unlabeled natural categories such as images of dogs and cats or male and female faces. More recent work has shown that infants and children take into account not only the unlabeled examples available, but the sampling process from which labeled examples arise .

Famous quotes containing the words learning, human and/or cognition:
“The first man to discover Chinook salmon in the Columbia, caught 264 in a day and carried them across the river by walking on the backs of other fish. His greatest feat, however, was learning the Chinook jargon in 15 minutes from listening to salmon talk.”
—State of Oregon, U.S. public relief program (1935-1943)
“Loyalty to petrified opinions never yet broke a chain or freed a human soul in this world—and never will.”
—Mark Twain [Samuel Langhorne Clemens] (1835–1910)
“Socratic man believes that all virtue is cognition, and that all that is needed to do what is right is to know what is right. This does not hold for Mosaic man who is informed with the profound experience that cognition is never enough, that the deepest part of him must be seized by the teachings, that for realization to take place his elemental totality must submit to the spirit as clay to the potter.”
—Martin Buber (1878–1965)
