Design review plays an important role in verifying design standards and ensuring or shortening the design cycle of the project in collaborative process plant CAD. Visualization of 3D process plant models is an essential feature to support design review in distributed design environment. To improve rendering performance, model simplification algorithms, such as levels of detail (LODs) and hierarchical levels of detail (HLODs), can be applied to process plant models. However, it is difficult to use available general model simplification algorithms to support reviewing complex models in process plant CAD. These algorithms always need unbearable time for preprocessing and are not designed to handle process plant models. They do not take the specific requirements of design review into account and may distort design feature and make them unrecognizable to the reviewer. To efficiently transmit models, various compression technologies can be applied to shrink the data size. However, transmitting the geometric model over the network during visualization is still a bottleneck of rendering performance. In this paper, a new, faster model simplification algorithm is proposed to simplify process plant models. Only the geometric parameters and topology information are transmitted. We compute LODs and HLODs according to the model's geometric parameters and design feature. We demonstrate its performance on complex process plant models composed of tens of millions of triangles. Overall, our approach is able to greatly shorten the preprocessing time and achieve considerable speedups in frame rate with little loss in image quality. © 2008 ACM.

This paper proposes a novel face recognition algorithm inspired by the selective attention of Human Visual System (HVS). We record four observers' eye movements when they are viewing 100 FRGC [1] frontal view face images and find that the observers are highly consistent in the regions fixated. Inspired by the fact that fovea of HVS has a much higher spatial acuity than the periphery, a face recognition algorithm based on spatial variant sampling is proposed to simulate such foveated imaging phenomenon, where more information is reserved for the fixated regions. Moreover, information extracted from glance which adopts the low spatial frequency components of the image is integrated into the face recognition system to elicit a percept that occurs before any fixations. The experimental results on FERET database [2] demonstrate that the proposed method not only reduces the computational cost, but also achieves comparable performance, which shows that the characteristics of the HVS provide valuable insights into face recognition. © 2011 IEEE.

By studying the way a previous study is using utility function with multi-choice goal programming (MCGP), some drawbacks are identified. These drawbacks can mistakenly result in an incomplete representativeness of the original MCGP with utility functions model and thus lead to the inability of the model to appropriately assess and express the real preference structure of a decision maker (DM). This study recommends some points and proposes another ways of using utility functions with MCGP. These new ways are validated by using them to express different DM preference structures pertaining to a goal, which underlies his/her real oral statements during decision making. © 2014 Springer science+Business Media Dordrecht.

For two-player games of perfect information such as Chess, we introduce "uniqueness" properties to describe game positions in which a winning strategy (should one exist) is forced to be unique. Depending on how uniqueness is forced, and whether it applies to both players, the uniqueness property is classified as (bi-) weak, (bi-) strong, or global. We prove that any reasonable two-player game G is extendable to a game G∗ with the bi-strong uniqueness property, so that e.g., QBF remains PSPACE-complete under this restriction. For global uniqueness, we introduce a simple game GUPQBF over Boolean formulas with this property, and prove that any reasonable two-player game with global uniqueness is reducible to this game. On the other hand, we also show that GUPQBF resides in "small" counting classes believed properly contained in PSPACE. Our results give a new characterization to some complexity classes such as PSPACE and EXPTIME. © Springer-Verlag Berlin Heidelberg 2002.

This works presents an innovative application of Markov Decision Process (MDP) to a medium-term mining logistics planning problem considering the mine-to-client supply chain. We implemented three distinct algorithms based on state-of-the-art approaches to solve large-scale problems, and compared their results. Furthermore, we combined all three variants in a single novel algorithm that attained fast convergence and may be an alternative to circumvent the curse of dimensionality underlying large scale problems. © 2020 EUCA.

CAM is widely used in microprocessors and SOC TLB modules. It gives great advantage for software development. And TLB operations become bottleneck of the microprocessor performance. The test cost of normal BIST approach of the CAM can not be ignored. The paper analyses the fault models of CAM and proposes an instruction suitable march-like algorithm. The algorithm requires 14N+2L operations, where N is the number of words of the CAM and L is the width of a word. The algorithm covers 100% targeted faults. Instruction-level test using the algorithm has not any test cost on area and performance. Moreover the algorithm can be used in BIST approaches and have less performance lost for microprocessors. The paper instances the algorithm in a MIPS compatible microprocessor and have good results. © 2008 IEEE.

This paper explores the development of a multilabel machine learning system for predicting both gender and age from human gait patterns. Gait analysis, a non-intrusive method of identifying subtle nuances in human movement, has proven to be a rich source of information related to demographic characteristics. The research extends beyond traditional single-label classification approaches, adopting a multilabel framework to simultaneously predict gender and age *** study evaluates various multilabel machine learning algorithms, with the Random k-labeLsets (RAKEL) algorithm demonstrating superior performance in predicting gender and age labels from human gait datasets. The accuracy of the algorithm can reach up to 87%. We also compared the multilabel approach with several multiclass algorithms such as Decision Tree, Random Forest, Gradient Boosting, K-Neighbors and XGBoost. However, when we also considering the training time, Classifier Chain algorithm showed the best trade off with the accuracy of 86% and the training time is twice faster than the RAKEL algorithm. © 2024 IEEE.

Smart villages that utilize digital technology are a solution to assist rural community services in meeting their needs, especially for developing countries. However, financial problems, namely the high cost of infrastructure, the size of the informal economy and governance are challenges in limiting the government’s aspirations regarding the smart village concept. The presentation of this article examines the state of smart village development in developing countries, which includes conceptual understanding, motivations, drivers and barriers to smart villages. The purpose of this study is to find answers to research questions by reviewing several selected study articles. The method used was to search for selected studies and there were 60 selected studies identified from a search of five literature databases which initially contained 3394 articles. The results of the data were analyzed using synthetic analysis and thematic analysis. The results of this study found data related to Concept, Technology, Barriers To Smart Village which came from several articles by answering questions from the research, namely RQ1: How many articles from the 10 most populous countries discussed Smart Village, RQ2: What are the basic dimensions of Smart Village, RQ3: What new technologies are discussed in Smart Village digitization, RQ4: What are the Challenges in Smart Village. The results of this SLR can also later be used as a reference for further researchers to find out the background of research related to smart villages. The conclusion obtained in this research is the end of the explanation of this article concludes that there are still many shortcomings in this research and it is hoped that in the future many studies will be able to explore other aspects such as regulations and others that are not discussed in the article so that it is expected to be a reference for further researchers to examine information related to smart villages. in order to find an ideal and up-to-date con

Terminology Learning through Taxonomy Discovery

Terminology Learning through Taxonomy Discovery

引用

Brazilian Conference on Intelligent Systems (BRACIS)

作者： Raphael Melo Kate Revoredo Aline Paes Postgraduate Information Systems Program UNIRIO Brazil Department of Computer Science Institute of Computing Brazil

Description Logics based languages have emerged as the standard knowledge representation scheme for ontologies. Typically, an ontology formalizes a number of dependent and related concepts in a domain, encompassed as a terminology. As defining such terminologies manually is a complex, time consuming and error-prone task, there is great interest and even demands for methods that learn terminologies automatically. Learning a terminology in Descriptions Logics concerns to learn several related concepts. This process would greatly benefit of an ideal order to determine which concept should be learned before another concept. Arguably, such an order would yield rich and readable terminologies, as previously, and interrelated concepts formerly learned could be used to induce the description of further concepts. In this work, we contribute with a formal definition of the concept and terminology learning problems and from such definitions we devise an algorithm for finding an ordering through concept taxonomy discovery, that should be followed when learning several related concepts. We show through an experiment that by following the order detected by the algorithm, we are able to afford a more readable terminology than methods that do not conceive an ideal order or do not learn concepts in a dependent way.
