我们研究了一个简单而通用的模板,用于构造仿射提取器,通过组成一个线性变换与弹性函数。使用这一点,我们表明,良好的仿射提取器可以计算的各种类型的非显式电路,包括AC 0-XOR电路:AC 0电路的奇偶校验门层的输入。我们还表明,单边提取器可以计算小DNF-XOR电路,并将这些电路从其他研究良好的类。作为研究DNF-XOR电路的进一步动机,我们表明,如果它们可以近似内积,那么小的AC 0-XOR电路可以精确地计算它-这是一个长期存在的开放问题。
We study a simple and general template for constructing affine extractors by composing a linear transformation with resilient functions. Using this we show that good affine extractors can be computed by non-explicit circuits of various types, including AC0-Xor circuits: AC0 circuits with a layer of parity gates at the input. We also show that one-sided extractors can be computed by small DNF-Xor circuits, and separate these circuits from other well-studied classes. As a further motivation for studying DNF-Xor circuits we show that if they can approximate inner product then small AC0-Xor circuits can compute it exactly – a long-standing open problem.
