In computational learning theory, the teaching dimension of a concept class C is defined to be, where is the minimum size of a witness set for c in C.
The teaching dimension of a finite concept class can be used to give a lower and an upper bound on the membership query cost of the concept class.
In Stasys Jukna's book "Extremal Combinatorics", a lower bound is given for the teaching dimension:
Let C be a concept class over a finite domain X. If the size of C is greater than
then the teaching dimension of C is greater than k.
Famous quotes containing the words teaching and/or dimension:
“Dogmatic toleration is nonsense: I would no more tolerate the teaching of Calvinism to children if I had power to persecute it than the British Raj tolerated suttee in India. Every civilized authority must draw a line between the tolerable and the intolerable.”
—George Bernard Shaw (1856–1950)
“Authority is the spiritual dimension of power because it depends upon faith in a system of meaning that decrees the necessity of the hierarchical order and so provides for the unity of imperative control.”
—Shoshana Zuboff (b. 1951)
