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:
“And hiving wisdom with each studious year,
In meditation dwelt, with learning wrought,
And shaped his weapon with an edge severe,
Sapping a solemn creed with solemn sneer.”
—George Gordon Noel Byron (1788–1824)
“Of a truth, Knowledge is power, but it is a power reined by scruple, having a conscience of what must be and what may be; whereas Ignorance is a blind giant who, let him but wax unbound, would make it a sport to seize the pillars that hold up the long- wrought fabric of human good, and turn all the places of joy as dark as a buried Babylon.”
—George Eliot [Mary Ann (or Marian)
“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)
