We study the bias of random bounded-degree polynomials over odd prime fields and show that, with probability exponentially close to 1, n-variate polynomials of degree d over F-p have bias at most p(-Omega(n/d)). This also yields an exponential tail bound on the weight distribution of Reed-Muller codes over odd prime fields. These results generalize bounds of Ben-Eliezer, Hod, and Lovett [Comput. Complexity, 21 (2012), pp. 63-81] who proved similar results over F-2. Our bounds are based on an extremal property of the rank of sub-matrices of the generator matrices of Reed-Muller codes over odd prime fields that generalizes a property shown by Keevash and Sudakov [SIAM T. Discrete Math., 18 (2005), pp. 713-727] for the case of F-2. Our tail bounds on the bias can be used to derive exponential lower bounds on the time for space-bounded learning of bounded-degree polynomials from their evaluations over odd prime fields. |
