Learning AC 0 circuits
Problem Definition
This problem deals with learning “simple” Boolean functions \( { f: \{0,1\}^n \rightarrow \{-1,1\} } \) from uniform random labeled examples. In the basic uniform distribution PAC framework, the learning algorithm is given access to a uniform random example oracle EX(f, U) which, when queried, provides a labeled random example \( { (x,f(x)) } \) where x is drawn from the uniform distribution U over the Boolean cube \( { \{0,1\}^n. } \) Successive calls to the EX(f, U) oracle yield independent uniform random examples. The goal of the learning algorithm is to output a representation of a hypothesis function \( { h: \{0,1\}^n \rightarrow \{-1,1\} } \) which with high probability has high accuracy; formally, for any \( { \epsilon, \delta > 0 } \), given ϵ and δ the learning algorithm should output an h which with probability at least \( { 1 - \delta } \) has \( { \Pr_{x \in U} [h(x) \neq f(x)] \leq \epsilon } \).
