We study correlation bounds and pseudorandom generators for depth-two circuits that consist of a SYM-gate (computing an arbitrary symmetric function) or THR-gate (computing an arbitrary linear threshold function) that is fed by S AND gates. Such circuits were considered in early influential work on unconditional derandomization of Luby, Veličković, and Wigderson [LVW93], who gave the first non-trivial PRG with seed length 2^O(√((S/ε))) that ε-fools these circuits. In this work we obtain thearXiv:1803.04553v1 fatcat:ynglyw7775fs5ho4mlu5rbrnwy
