'''Computational learning theory''' is the branch of [[Learning Theory|learning theory]] that studies learning under computational constraints. Where formal learning theory asks which concept classes are learnable in principle, computational learning theory asks which are learnable in polynomial time — and which require resources that grow exponentially with problem size. The field's central framework is PAC (Probably Approximately Correct) learning, introduced by Leslie Valiant in 1984, which demands that a learner produce a hypothesis that is probably approximately correct, using time and sample size polynomial in the relevant parameters.

The computational perspective transforms philosophical questions about induction into complexity-theoretic ones. A concept class may be learnable in the limit yet not PAC-learnable; it may be PAC-learnable only with access to membership queries or only with improper hypotheses. The boundary between tractable and intractable learning mirrors the broader [[P versus NP|P versus NP]] boundary, and some of the deepest open questions in the field concern whether natural concept classes — neural network architectures, decision trees, boolean formulas — are efficiently learnable under standard cryptographic assumptions.
