The estimations include both the model parameters and two reliability metrics, namely, the reliability and failure rate functions. Both maximum likelihood and maximum product of spacing are studied from the conventional estimation standpoint. Along with the point estimations utilizing the two traditional approaches, the approximate confidence intervals based on both are also examined. The Bayesian point estimations with the squared error loss function and credible intervals for various parameters are investigated. Depending on the source of observed data, Bayesian estimations are obtained using two different types of posterior distributions. Numerous censoring designs are looked at in the simulation study to compare the accuracy of classical and Bayesian estimations. Using both conventional methodologies, several optimality metrics are suggested to identify the best removal design. One chemical and a pair of engineering actual data sets are examined to support the significance of the indicated methodologies. The analysis showed that the Bayesian estimation, using the likelihood function, is preferable when compared to other classical and Bayesian methods.</p>\u0000 </div>","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2024 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-10-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/4848673","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142429226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This model is based on factors such as user interactivity, event activity, duration of the event, freshness of events,media attention, and the event heat decay ratio. It evaluates event heat, calculates the influence of events, identifies hot events with a high level of discussion, selects these hot events, and validates the findings through experiments.

Describing the nature of these interactions has been a challenging task yet important for neurodegenerative disease evolution. Fusing modern dynamic graph network theory techniques and control theory applied on complex brain networks creates a new framework for neurodegenerative disease research by determining disease evolution at the subject level, facilitating a predictive treatment response and revealing key mechanisms responsible for disease alterations. It has been shown that two types of controllability—the average and the modal controllability—are relevant for the mechanistic explanation of how the brain navigates between cognitive states. The average controllability favors highly connected areas which move the brain to easily reachable states, while the modal controllability favors weakly connected areas representative for difficult-to-reach states. We propose two different techniques to achieve these two types of controllability: a centrality measure based on a sensitivity analysis of the Laplacian matrix is employed to determine the average controllability, while graph distances form the basis of the modal controllability. The concepts of “choosing the best driver set” and “graph distances” are applied to measure the average controllability and the modal controllability, respectively. Based on these new techniques, we obtain important disease descriptors that visualize alterations in the disease trajectory by revealing densely connected hubs or sparser areas.

There are many metrics that are available but not desired to a practitioner. This paper recommends in a plausible reasoning manner an easy-to-understand method to construct desired distance-like measures: to fuse easy-to-obtain (or easy to coined by practitioners) pseudo-semimetrics, pseudometrics, or metrics by making full use of well-known t-norms, t-conorms, aggregation operators, and similar operators (easy to coined by practitioners et al). The simple reason to do this is that data for a real-world problem are sometimes full of multiagents. A distance-like notion, called weak interval-valued pseudometric (briefly, WIVP metric), is defined by using known notions of pseudo-semimetric, pseudometric, and metric; this notion is topological good and shows precision, flexibility, and compatibility than single pseudo-semimetric, pseudometric, or metric. Propositions and detailed examples are given to illustrate how to fabricate (including using what “material”) an expected or demanded WIVP metric (even interval-valued metric) in practical problems, and WIVP metric and its special cases are characterized by using axioms. Moreover, some WIVP-metrics pertinent to quantitative logic theory or interval-valued fuzzy graphs are constructed, and fixed point theorems and common fixed point theorems in weak interval-valued metric spaces are also presented. Topics and strategies for further study are also put forward concretely and clearly.&lt;/p&gt;&lt;p&gt;In many cases, the measure values of true data are not unique (but two or more) for uncertainty or complexity. For example, there are several agents in China that value and order all periodicals published in China. Peking University Library and Nanjing University Library are generally thought to be the best two and incomparable to each other. For a journal &lt;i&gt;J&lt;/i&gt;, assume the orders given by Peking University Library and the Nanjing University Library are &lt;i&gt;m&lt;/i&gt;-th and &lt;i&gt;n&lt;/i&gt;-th, respectively; then, &lt;i&gt;m&lt;/i&gt; and &lt;i&gt;n&lt;/i&gt; may be not the same in general. There are also many other examples. In 2012, breakthrough of the selected by the famous journal Science is different from those selected by the famous journal Nature; Gini coefficients in China in 2012 from two different agents are 0.481 and 0.61, respectively; the Chebyshev distance (resp., the Euclidean distance, the Manhattan distance or the city block distance, and the river distance) between two points (0,1) and (1,2) in the Euclidean plane &lt;i&gt;R&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; is 1 (resp., &lt;span&gt;&lt;/span&gt;&lt;math&gt;&lt;/math&gt;, 2, 3).

This knowledge is valuable across various disciplines like marketing, management, epidemiology, homeland security, and psychology. An essential task within network analysis is deciphering the structure of complex networks including technological, informational, biological, and social networks. Understanding this structure is crucial for comprehending network performance and organization, shedding light on their underlying structure and potential functions. Community structure detection aims to identify clusters of nodes with high internal link density and low external link density. While there has been extensive research on community structure detection in single-layer networks, the development of methods for detecting community structure in multilayer networks is still in its nascent stages. In this paper, a new method, namely, IGA-MCD, has been proposed to tackle the problem of community structure detection in multiplex networks. IGA-MCD consists of two general phases: flattening and community structure detection. In the flattening phase, the input multiplex network is converted to a weighted monoplex network. In the community structure detection phase, the community structure of the resulting weighted monoplex network is determined using the Improved Genetic Algorithm (IGA). The main aspects that differentiate IGA from other algorithms presented in the literature are as follows: (a) instead of randomly generating the initial population, it is smartly generated using the concept of diffusion. This makes the algorithm converge faster. (b) A dedicated local search is employed at the end of each cycle of the algorithm. This causes the algorithm to come up with better new solutions around the currently found solutions. (c) In the algorithm process, chaotic numbers are used instead of random numbers. This ensures that the diversity of the population is preserved, and the algorithm does not get stuck in the local optimum. Experiments on the various benchmark networks indicate that IGA-MCD outperforms state-of-the-art algorithms.</p>\u0000 </div>","PeriodicalId":50653,"journal":{"name":"Complexity","volume":"2024 1","pages":""},"PeriodicalIF":1.7,"publicationDate":"2024-08-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/1016086","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142100445","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
