Reduced-Order and Full-Order Interval Observers Design for Discrete-Time System
IEEE Access, 2020 In this paper, the design of reduced-order and full-order interval observers for discrete-time system is investigated. First, the original system is transformed into a descriptor system with the ability to estimate the unknown noise of sensors.

An interval Kalman filter enhanced by lowering the covariance matrix upper bound
International Journal of Applied Mathematics and Computer Science, 2021 This paper proposes a variance upper bound based interval Kalman filter that enhances the interval Kalman filter based on the same principle proposed by Tran et al. (2017) for uncertain discrete time linear models.

Interval-valued Matrix Factorization with Applications [PDF]
2010 IEEE International Conference on Data Mining, 2010 In this paper, we propose the Interval-valued Matrix Factorization (IMF) framework. Matrix Factorization (MF) is a fundamental building block of data mining. MF techniques, such as Nonnegative Matrix Factorization (NMF) and Probabilistic Matrix Factorization (PMF), are widely used in applications of data mining. For example, NMF has shown its advantage

Two Approximation Models of Fuzzy Weight Vector from a Comparison Matrix
Advances in Fuzzy Systems, 2018 In this study, our uncertain judgment on multiple items is denoted as a fuzzy weight vector. Its membership function is estimated from more than one interval weight vector. The interval weight vector is obtained from a crisp/interval comparison matrix by

Construction of Hurwitz stability intervals for matrix families
Dolomites Research Notes on Approximation, 2023 Summary: In this work, matrix families which consist of linear sum and convex combination have been determined. In this process, Hurwitz stability, sensitivity and continuity theorems have been mentioned. The intervals \(\mathcal{I}_{\mathcal{L}}\) and \(\mathcal{I}_{\mathcal{C}}\) of the matrix families have been determined so that the linear sum ...

A new view to uncertainty in Electre III method by introducing interval numbers [PDF]
Decision Science Letters, 2012 The Electre III is a widely accepted multi attribute decision making model, which takes into account the uncertainty and vagueness. Uncertainty concept in Electre III is introduced by indifference, preference and veto thresholds, but sometimes ...

Incidence matrix and cover matrix of nested interval orders
The Electronic Journal of Linear Algebra, 2012 For any poset P , its incidence matrix n and its cover matrix C are the P × P (0, 1) matrices such that n(x, y) = 1 if any only if x is less than y in P and C(x, y) = 1 if any only if x is covered by y in P. It is shown that n and C are conjugate to each other in the incidence algebra of P over a field of characteristic 0 provided P is the nested ...
