Abstract

In this paper, we investigate inverse problems of the interval query problem in application to data mining. Let I be the set of all intervals on U={0, 1, 2,.., n}. Consider an objective function f(I), conditional functions ui(I) on I, and define an optimization problem of finding the interval I maximizing f(I) subject to ui(I) > Ki for given real numbers Ki (i=1, 2,.., h). We propose efficient algorithms to solve the above optimization problem if the objective function is either additive or quotient, and the conditional functions are additive, where a function f is additive f(I) = Σi I f(i) extending a function f on U, and quotient if it is represented as a quotient of two additive functions. We use computational-geometric methods such as convex hull, range searching, and multidimensional divide-and-conquer.
