NEW CRITERIA FOR RULE SELECTION IN FUZZY LEARNING CLASSIFIER SYSTEMS
Designing an effective criterion for selecting the best rule is a major problem in theprocess of implementing Fuzzy Learning Classifier (FLC) systems. Conventionally confidenceand support or combined measures of these are used as criteria for fuzzy rule evaluation. In thispaper new entities namely precision and recall from the field of Information Retrieval (IR)systems is adapted as alternative...
متن کاملOn canonical number systems
Let P (x) = pdx + . . . + p0 ∈ Z[x] be such that d ≥ 1, pd = 1, p0 ≥ 2 and N = {0, 1, . . . , p0 − 1}. We are proving in this note a new criterion for the pair {P (x),N} to be a canonical number system. This enables us to prove that if p2, . . . , pd−1, ∑d i=1 pi ≥ 0 and p0 > 2 ∑d i=1 |pi|, then {P (x),N} is a canonical number system.

متن کاملCanonical Number Systems, Counting Automata and Fractals
In this paper we study properties of the fundamental domain Fβ of number systems, which are defined in rings of integers of number fields. First we construct addition automata for these number systems. Since Fβ defines a tiling of the n-dimensional vector space, we ask, which tiles of this tiling “touch” Fβ . It turns out, that the set of these tiles can be described with help of an automaton, ...
متن کاملOn the Characterization of Canonical Number Systems
It is well known that each positive integer n can be expressed uniquely as a sum n = d0 + d1b + . . . + dhb h with an integral base number b ≥ 2, dh 6= 0 and di ∈ {0, . . . , b − 1}. This concept can be generalized in several directions. On the one hand the base sequence 1, b, b, . . . can be replaced by a sequence 1 = u0 < u1 < u2 < . . . to obtain representations of positive integers. Of spec...
