Fourier Entropy-Influence Conjecture for Random Linear Threshold Functions

Computational Complexity 2019-03-29 v1

Abstract

The Fourier-Entropy Influence (FEI) Conjecture states that for any Boolean function f:{+1,1}n{+1,1}f:\{+1,-1\}^n \to \{+1,-1\}, the Fourier entropy of ff is at most its influence up to a universal constant factor. While the FEI conjecture has been proved for many classes of Boolean functions, it is still not known whether it holds for the class of Linear Threshold Functions. A natural question is: Does the FEI conjecture hold for a `random' linear threshold function? In this paper, we answer this question in the affirmative. We consider two natural distributions on the weights defining a linear threshold function, namely uniform distribution on [1,1][-1,1] and Normal distribution.
