Regression represents one of the most basic building blocks of data analysis and AI. Despite growing interest in interval-valued data across various fields, approaches to establish regression models for interval-valued data which address and handle t

In this paper, we discussed risk evaluation decision models combined cross-entropy and risk preference under interval type-2 fuzzy environment, in which all attribute values provided by expert take the form of interval type-2 fuzzy sets(IT2FSs). Firs

This paper provides a new methodology for determining a word's interval type-2 fuzzy set model using only one subject, a Person FOU. It uses interval end-point uncertainty intervals instead of only the end-point intervals. Such uncertainty intervals

In many practical situations, we need, given the values of the observed quantities x1, ⋯, xn, to predict the value of a desired quantity y. To estimate the accuracy of a prediction algorithm f(x1, ⋯, xn), we need to compare the results of this al

In many practical problems such as radar imaging, it is useful to compute the variance-to-mean ratio. The need is important because for the sum of k identical independent signal components, both the variance and the mean are multiplied by k, so this

The used numbers of the method of AHP are precise numbers, so the paper applies interval numbers to the method of AHP, forming the method of I-F-AHP, which is a better method for expressing the thinking of people and the complexity of thing than AHP,

The flood disaster is one of the most serious natural disasters. It is the important basis of making plan for flood control to assess flood losses accurately. The results of the common assessment methods are discrete values and low resolution which a

In traditional statistics, we usually assume that we know the exact probability distributions. In practice, we often only know the probabilities with interval uncertainty. The main emphasis on taking this uncertainty into account has been on situatio

In practice, it is often necessary to make a decision under uncertainty. In the case of interval uncertainty, for each alternative i, instead of the exact value vi of the objective function, we only have an interval vi = [vi-,vi-.] of possible values

With respect to fuzzy AHP group decision-making problem in which the result is fuzzy number, a new method of fuzzy AHP is presented based on set-valued statistics. Firstly the definition of uniformly interval number judgment matrix is given; secondly
