Abstract

In this paper, Boolean functions in ,4C0 are studied using harmonic analysis on the cube.The main result is that an ACO Boolean function has almost all of its "power spectrum" on the low-order coefficients.An important ingredient of the proof is Hastad's switching lemma [8].This result implies several new properties of functions in -4C[': Functions in AC() have low "average sensitivity;" they may be approximated well by a real polynomial of low degree and they cannot be pseudorandom function generators.Perhaps the most interesting application is an O(n POIYIOg(n ')-time algorithm for learning functions in ACO.The algorithm observes the behavior of an AC'" function on O(nPO'Y'Og(n)) randomly chosen inputs, and derives a good approximation for the Fourier transform of the function.This approximation allows the algorithm to predict, with high probability, the value of the function on other randomly chosen inputs.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
