One of the most important variables in cycling is the oxygen consumption (VO2) and its maximal value (‘VO2max’). The latter is considered as an appropriate indicator of the cardio-respiratory fitness and provides interesting information for many applications in the sports medicine context, however, this variable is not easy to measure out of a laboratory. Hence, this paper presents an alternative approach to the estimation of VO2 dynamics by means of fuzzy systems that use an input vector composed of three easy-to-obtain variables: Heart Rate, Work Rate, and Respiratory Rate measured in a clinical Cardiopulmonary-Exercise Testing. Two tuning strategies are compared: the well-known adaptive-network-based fuzzy inference system and an evolutionary fuzzy system based on the differential evolution algorithm. Experimental results showed that both tuning strategies are capable of providing competitive solutions in terms of several regression indices.
循环中最重要的变量之一是耗氧量(VO2)及其最大值(VO2max)。后者被认为是心肺健康的适当指标,并为运动医学中的许多应用提供了有趣的信息,然而,这个变量不容易在实验室之外测量。因此,本文提出了一种通过模糊系统来估计VO2动态的替代方法,该系统使用由三个易于获得的变量组成的输入向量:心率,工作速率和呼吸速率,这些变量是在临床心肺运动测试中测量的。比较了两种调优策略:基于自适应网络的模糊推理系统和基于差分进化算法的进化模糊系统。实验结果表明,两种调优策略都能在多个回归指标上提供有竞争力的解。

In this paper, we introduce a variant of the Adaptive Network-based Fuzzy Inference System (ANFIS). The proposed variant does not use backpropagation and grid partitioning. Scatter partitioning is employed by complementing the least-squares method with Tikhonov regularization, both in standard and fractional version. The application example is the prediction of the burnt area in forest fires. We used two publicly available datasets for the numerical experiments. The results encourage further investigations.

In the problem of multi-class classification, researchers have proved that we can train a classifier that has good performance on the test set, as long as the training and test sets are precisely drawn from the same distribution and the size of the training set approaches infinity. However, in a realworld situation, such precise observations are often unavailable in some cases. For example, readings on analogue measurement equipment are not precise numbers but intervals since there is only a finite number of decimals available. Hence, in this paper, we propose a more realistic problem called learning from imprecise observations (LIMO), where we train a classifier with fuzzy observations (i.e., fuzzy vectors). We prove the estimation error bound of this novel problem based on the distribution of fuzzy random variables. This bound demonstrates that we can always learn the best classifier when we have infinite fuzzy observations. We also develop a practical algorithm to train a classifier using fuzzy observations. The experiment results verify the efficacy of our theory and algorithm.
在多类分类问题中,研究人员已经证明,只要训练集和测试集精确地取自同一分布,并且训练集的大小趋近于无穷大,我们就可以在测试集上训练出性能良好的分类器。然而,在现实世界的情况下,这种精确的观察在某些情况下往往是不可用的。例如,模拟测量设备上的读数不是精确的数字,而是间隔,因为只有有限数量的小数可用。因此,在本文中,我们提出了一个更现实的问题,称为从不精确观察中学习(LIMO),其中我们用模糊观察(即模糊向量)训练分类器。基于模糊随机变量的分布,证明了该问题的估计误差界。这个界限表明,当我们有无限模糊观察时,我们总是可以学习到最好的分类器。我们还开发了一个实用的算法来训练分类器使用模糊观察。实验结果验证了理论和算法的有效性。

In the paper, we show how the importance of individual ranges of values of attributes describing cases can be determined using the attribute fuzzification process. The importance is determined on the basis of classification capabilities. The described approach is based mainly on fuzzy set theory and the rough set based discretization method. Moreover, an experimental study of the computer-aided classification task is presented.

Image features extractor based on hybridization of fuzzy controller and meta-heuristic 基于模糊控制器和元启发式混合的图像特征提取方法

The image recognition task is one of the fundamental aspects of image and video analysis. Recognition of individual objects allows for further inference or analysis. Unfortunately, quite often the detection and recognition itself are difficult tasks. Especially if there are many different objects in the image, or if there is some noise. In this paper, we propose a method for extracting specific features from images. The proposition is a hybridization of two main tools - meta-heuristic and fuzzy system. At first, an objective function is created for a specific object, then the meta-heuristic is used for analyzing an image for finding the best features. The operation of creating an objective function and then interpreting the position of individuals in the metaheuristic is evaluated by a fuzzy controller. The use of fuzzy logic enables the creation of decision sets during data analysis. This is possible through the adaptive technique of improving the value of the membership functions in Takagi-Sugeno systems. A fuzzy approach shows great potential in analyzing the position in the image. The proposed feature extraction mechanism has been tested and discussed due to the possibility of using fuzzy logic as well as its hybridization with meta-heuristics.
图像识别任务是图像和视频分析的一个基本方面。对单个对象的识别允许进一步的推理或分析。不幸的是,检测和识别本身往往是一项艰巨的任务。特别是如果图像中有许多不同的物体,或者有一些噪声。在本文中,我们提出了一种从图像中提取特定特征的方法。命题是两种主要工具——元启发式和模糊系统的混合。首先,为特定对象创建目标函数,然后使用元启发式对图像进行分析以寻找最佳特征。通过模糊控制器对创建目标函数并解释元启发式中个体位置的操作进行评价。使用模糊逻辑可以在数据分析期间创建决策集。这可以通过提高Takagi-Sugeno系统中隶属函数值的自适应技术来实现。模糊方法在分析图像中的位置方面显示出巨大的潜力。由于使用模糊逻辑的可能性以及它与元启发式的杂交,所提出的特征提取机制已经被测试和讨论。

In this contribution we analyze a real DNS traffic collected at the University of Rzeszów campus. All DNS queries and responses observed in the entire network were gathered. Data include traffic generated by students, scholars, and other staff members as well as servers, IoT and all other devices connected to network. Data was collected using the Tshark network protocol analyzer and stored in a ClickHouse columnar-oriented database dedicated for high volume data analyses. Fuzzy C-means clustering was applied to analyze DNS traffic and to distinguish between human- and machine generated traffic. Analysis was performed on a representative sample containing 3 516 094 records and 33 proposed features.

In this paper, we propose an approach to handling uncertain time intervals and related qualitative relations, based on possibility theory. Four contributions are included in this approach. (1) Representing uncertain time intervals and related qualitative relations by extending the 4D-fluents approach with new ontological components. (2) Reasoning about uncertain time intervals by extending the Allen's interval algebra. The resulting interval relations preserve the good properties of the original algebra. (3) Proposing an OWL 2 possibilistic temporal ontology based on 4D-fluents approach extension and Allen's interval algebra extension. The proposed qualitative temporal relations are inferred via a set of SWRL rules. We validate our work by implementing a prototype based on this ontology. (4) Applying our work to PersonLink ontology and comparing the obtained results with our previous works.

The selection of an appropriate method of data analysis is a key problem for researchers from various fields of applications. They consider different methods of data classification, often based on the thematic scope of the data at their disposal. However, various data characteristics, such as data set size, data type and quality, gaps, outliers and other anomalies, can make proper selection significantly difficult. Therefore, in this study we propose a method based on a very universal classifier designed on the basis of calculations using information granules. The main objective of the work is to present and comprehensively verify the effectiveness of the classifier. As an example of application, we propose complicated yet currently important data coming from widely understood ecological research. Detailed numerical experiments indicate the high efficiency of the proposed method and the possibility of easy application to data appearing in other fields. In addition, various types of aggregation functions of the classification results are considered in order to obtain the most reliable results for the discussed problems,
选择合适的数据分析方法是各个应用领域研究人员面临的关键问题。他们考虑不同的数据分类方法,通常基于他们所掌握的数据的主题范围。然而,各种数据特征,如数据集大小、数据类型和质量、差距、异常值和其他异常值,会使正确的选择变得非常困难。因此,在本研究中,我们提出了一种基于基于信息颗粒计算设计的非常通用的分类器的方法。这项工作的主要目的是展示和全面验证分类器的有效性。作为应用的例子,我们提出了来自广泛理解的生态学研究的复杂但目前重要的数据。详细的数值实验表明,该方法效率高,且易于应用于其他领域出现的数据。此外,为了对所讨论的问题获得最可靠的结果,还考虑了分类结果的各种类型的聚合函数。

In this work, the affine equivalent model (AEM) is developed by using only the controlled systems's input-output data and it's relation based on fuzzy rules. Multi-input fuzzy rules emulated network (MiFREN) is used as function approximator when learning laws are designed to reduce the model error. Furthermore, AEM stability is guaranteed according to Lyapunov by theorem III.1. Thereafter, the control law is proposed with the information obtained by AEM. The tracking error resulted from the closed-loop system is proved as a convergent sequence by Lemma IV.1. The main advantage results in a simple control scheme and low computational cost. Numerical discrete-time systems (linear and nonlinear) are used to validate the performance of the proposed scheme altogether with the comparison results.
本文仅利用被控系统的输入输出数据及其基于模糊规则的关系,建立了仿射等效模型。在设计学习规律时,采用多输入模糊规则仿真网络(MiFREN)作为函数逼近器来减小模型误差。进一步,根据Lyapunov定理III.1,保证了AEM的稳定性。然后,利用AEM获取的信息提出控制律。利用引理IV.1证明了闭环系统引起的跟踪误差是一个收敛序列。其主要优点是控制方案简单,计算成本低。数值离散系统(线性和非线性)与比较结果一起验证了所提方案的性能。

Requirement selection is an essential component of software release planning, which finds, for a given budget, an optimal subset of the requirements with the highest value. However, due to the dependencies among software requirements, selecting or ignoring a requirement may impact the values of others. But such Value Dependencies are imprecise and hard to capture; they have been ignored by the existing requirement selection methods, increasing the risk of value loss in software projects. To address this, we have proposed a fuzzy-based optimization method with two main components: (i) a fuzzy-based technique for modeling value dependencies and capturing their imprecision, and (ii) an Integer Linear Programming (ILP) model that takes into account value dependencies in software requirement selection. The scalability and effectiveness of the method in mitigating value loss are demonstrated through simulations.
需求选择是软件发布计划的重要组成部分,对于给定的预算,需求选择是具有最高价值的最优子集。然而,由于软件需求之间的依赖性,选择或忽略一个需求可能会影响其他需求的值。但是这种价值依赖是不精确的,很难捕捉;它们被现有的需求选择方法所忽略,增加了软件项目中价值损失的风险。为了解决这个问题,我们提出了一种基于模糊的优化方法,该方法有两个主要组成部分:(i)基于模糊的技术,用于建模值依赖关系并捕获它们的不精确性,以及(ii)在软件需求选择中考虑值依赖关系的整数线性规划(ILP)模型。通过仿真验证了该方法在减少价值损失方面的可扩展性和有效性。
