“…The goal of the learner is to construct a high-accuracy hypothesis function h, i.e., one which satisfies Pr[f (x) = h(x)] ≤ ǫ where the probability is with respect to the uniform distribution and ǫ is an error parameter given to the learning algorithm. Algorithms and hardness results in this framework have interesting connections with topics such as discrete Fourier analysis [Man94], circuit complexity [LMN93], noise sensitivity and influence of variables in Boolean functions [KKL88,BKS99,KOS04,OS07], coding theory [FGKP06], privacy [BLR08,KLN + 08], and cryptography [BFKL93,Kha95]. For these reasons, and because the model is natural and elegant in its own right, the uniform distribution learning model has been intensively studied for almost two decades.…”
