Moncler Kids them by reference to a number
In standard arithmetic, if we, e.g., accidentally add a wrong number y to the preliminary result x, we can undo this operation by subtracting y from the result x + y. In this paper, we prove the following two results: •• First, a similar possibility to invert (undo) addition holds for fuzzy numbers (although in case of fuzzy numbers, we cannot simply undo addition by subtracting y from the sum).•• Second, if we add a single fuzzy set that is not Moncler Down Jackets Uk a fuzzy number, we lose invertibility.Thus, invertibility requirement leads to a new characterization of the class of all fuzzy numbers. The Nearest Neighbour Classifier accepts patterns in the form of points in a descriptor space and classifies them by reference to a number of stored labelled points called locates. Training procedures for such classifiers have in the past consisted of a set of rules for selecting Moncler Kids various members of the training set for use as locates. This paper describes an alternative approach in which the locates do not necessarily represent real patterns, and the training procedure consists of adjusting the positions of the locates so as to optimise the decision surface.
