  • 摘要:

    In this paper, we prove that most of the boolean functions, f:−11n−11 satisfy the Fourier Entropy Influence (FEI) Conjecture due to Friedgut and Kalai (Proc. AMS'96)\cite{FG96}. The conjecture says that the Entropy of a boolean function is at most a constant times the Influence of the function. The conjecture has been proven for families of functions of smaller sizes. O'donnell, Wright and Zhou (ICALP'11)\cite{DWZ11} verified theconjecture for the family of symmetric functions, whose size is 2n+1. They are in fact able to prove the conjecture for the family of d-part symmetric functions for constant d, the size of whose is 2O(nd). Also it is known that the conjecture is true for a large fraction of polynomial sized DNFs (COLT'10)\cite{KLW10}. Using elementary methods we prove that a random function with high probability satisfies the conjecture with the constant as (2+), for any constant 0">0.
