The study of the sensitivity and the specificity of a classification test constitute a powerful kind of analysis since it provides specialists with very detailed information useful for cancer diagnosis. In this work, we propose the use of a multiobjective genetic algorithm for gene selection of Microarray datasets. This algorithm performs gene selection from the point of view of the sensitivity and the specificity, both used as quality indicators of the classification test applied to the previously selected genes. In this algorithm, the classification task is accomplished by Support Vector Machines; in addition a 10-Fold Cross-Validation is applied to the resulting subsets. The emerging behavior of all these techniques used together is noticeable, since this approach is able to offer, in an original and easy way, a wide range of accurate solutions to professionals in this area. The effectiveness of this approach is proved on public cancer datasets by working out new and promising results. A comparative analysis of our approach using two and three objectives, and with other existing algorithms, suggest that our proposal is highly appropriate for solving this problem. 相似文献

《公共建筑设计原理》是建筑学本科教学中传统的理论基础课。虽然有专指委推荐的统一教材,但却很难完美的适应全国上百所建筑院校不同的发展状态和教学目标。而且,即使教材传达的核心设计观念具有跨越时空的普适性,但采用的案例以及某些教学内容的时代特色仍然不够鲜明,因此,适当的内容增补以及教法上的改善必然成为各院系为适应本校特殊情况的必然之举。烟台大学建筑系因此也进行了必要的教学改革,以努力适应地域以及时代的需要。 相似文献

In earlier work [1], NIST developed a climate suitability analysis method to evaluate the potential of a given location for direct ventilative cooling and nighttime ventilative cooling. The direct ventilative cooling may be provided by either a natural ventilation system or a fan-powered economizer system. The climate suitability analysis is based on a general single-zone thermal model of a building configured to make optimal use of direct and/or nighttime ventilative cooling. This paper describes a new tool implementing this climate suitability methodology and its capability to consider an adaptive thermal comfort option and presents results from its application to analyze a variety of U.S. climates. The adaptive thermal comfort option has the potential to substantially increase the effectiveness of natural ventilation cooling for many U.S. cities. However, this impact is very dependent on the acceptable humidity range. If a dewpoint limit is used, the increase is significant for a dry climate such as Phoenix but much smaller for humid climates such as Miami. While ASHRAE Standard 55 does not impose a limit on humidity when using the adaptive thermal comfort option, the necessity of limiting humidity for other reasons needs to be considered. 相似文献

Online discussion forums, which are full of user-generated content including user opinions and comments, are a potential gold mine for exploring new and useful ideas to augment competence in innovation. Companies need to systematically analyze and interpret online commentaries to enhance in-house research and design activities. To this end, a framework is proposed using a design science approach to enable automatic analysis of the content of online opinions and comments in connection with specific products, using a web lexicon established for this purpose. Furthermore, this framework is applied to an automobile as a proof-of-concept. Several nicknames for the car brand studied were created by web users, some with irony and sarcasm. A few metaphorical expressions were also used to describe product features. Engineering practitioners should recognize the importance of stylized online expressions in order to have a better understanding of customer needs and expectations through the application of this framework, which incorporates an evolutionary web lexicon. 相似文献

One of the negative side effects experienced by users when interacting with virtual environment is visual symptoms. This paper explores the ergonomics design parameters of the virtual environment to minimize such negative side effect by applying axiomatic design principles. Axiomatic design is a method to provide a systematic way for designing products and large systems. The independence axiom is used to map customer domain (CAs) to functional domain (FRs) and physical domain (DPs). A paper based survey was conducted to identify and define customers' preference in the virtual environment. A virtual robot manufacturing system was developed as a case study to explore ergonomic design parameters that satisfy the independence of FRs and CAs. Results of this study shows that the ergonomic design parameters of virtual environment identified (DP161-DP162-DP121-DP111-DP131-DP141-DP151-DP152) have satisfied the independence functional requirement and desired visual comfort for users. By uncoupling the design it provides an efficient and effective sequence of design activities FR161-FR162-FR121-FR111-FR131-FR141-FR151-FR152. 相似文献
