Many complicated systems of practical interest consist basically of a well-defined outer shell-like master structure and a complicated internal structure with uncertain dynamic properties. Using the "fuzzy structure theory" for predicting audible frequency vibration, the internal structure is considered as one or more fuzzy substructures that are known in some statistical sense only. Experiment...

In fuzzy modelling, the identification method used is very important. Identification for fuzzy modelling has two aspects: structure identification and parameter identification. In general, structure identification is a difficult and extremely ill-defined process and not readily amenable to automated techniques. The problem of parameter identification is closely related to the estimation of the ...

This paper presents a new hybrid neuro-fuzzy model which is capable of learning structure and parameters by means of recursive binary space partitioning BSP. Introduction Neuro-fuzzy systems (NFSs) [1] combine the learning ability of artificial neural nets (ANNs) with the linguistic interpretation capacity of fuzzy inference systems (FISs) [2]. This work makes use of BSP (Binary Space Partition...

This article presents an adversary detection mechanism and a resilient control framework for multiagent systems under spatiotemporal constraints. Safety in is typically addressed the assumption that all agents collaborate to ensure forward invariance of desired safe set. work analyzes agent behaviors based on certain behavior metrics, designs proactive notion critical region system operation. I...

Previous studies on robustness have argued that there is a tradeoff between accuracy and adversarial accuracy. The can be inevitable even when we neglect generalization. We argue the inherent to commonly used definition of accuracy, which uses an adversary construct points constrained by $\epsilon$-balls around data points. As $\epsilon$ gets large, may use real from other classes as examples. ...

The aim of this paper is to introduce $(L,M)$-fuzzy closurestructure where $L$ and $M$ are strictly two-sided, commutativequantales. Firstly, we define $(L,M)$-fuzzy closure spaces and getsome relations between $(L,M)$-double fuzzy topological spaces and$(L,M)$-fuzzy closure spaces. Then, we introduce initial$(L,M)$-fuzzy closure structures and we prove that the category$(L,M)$-{bf FC} of $(L,M...
