Abstract

Abstract: In this paper，a discrete algorithm is proposed based on the frequency supervised breakpoint which is applied to the conditional continuous attributes.The algorithm adopts the idea of frequency supervised breakpoint that is brought forward to generate initial breakpoints.On the basis of the preparatory work，reduction of breaktpoints has been performed.The result obtained shows clearly the breakpoints generated by this algorithm not only are in line with the actual data distribution but also they are more reasonable，refined.

Key words: frequency-supervised-breakpoint, equivalent, discretization
