Abstract

We give an algorithm to PAC-learn the coeffcients of a multivariate polynomial from the signs of its values, over a sample of real points which are only known approximately. While there are several papers dealing with PAC-learning polynomials, they mainly only consider variables over finite fields or real variables with no round-off error. In particular, to the best of our knowledge, the only other work considering rounded-off real data is that of Dennis Cheung. There, multivariate polynomials are learned under the assumption that the coeffcients are independent, eventually leading to a linear programming problem. In this paper we consider the other extreme: namely, we consider the case where the coeffcients of the polynomial are (polynomial) functions of a single parameter.
