基于DIKW图谱的虚拟社区用户性格分类与转换方法

随着社交网络的发展，网络虚拟社区的成员数量快速增长.在虚拟社区中，用户会偏向选择浏览自己喜欢的内容，同时倾向与具有相近或相关兴趣爱好或目的的人进行内容交流与处理合作.在虚拟社区中，用户之间的交互内容以数据、信息和知识的形态存在.虚拟社区上大量的数据、信息与知识形态的网络类型化资源中保留了许多网络用户使用“痕迹”.这些痕迹是真实用户的数字化存在代表.为了实现对虚拟社群用户生成内容按照偏好和兴趣进行量化调控，采用数据信息知识及智慧（data information knowledge wisdom，DIKW）图谱对这些类型资源进行建模.根据用户DIKW图谱结合自我构建理论将用户按性格指数进行进一步的归类，并根据DIKW图谱结合自我决定理论将用户的心理需求分类.根据性格指数和心理需求设计了针对不同用户的不同的性格转换方法，模拟了用户生成内容的产生.     

The total cost of misclassification in credit scoring: A comparison of generalized linear models and generalized additive models

This study examines whether the evaluation of a bankruptcy prediction model should take into account the total cost of misclassification. For this purpose, we introduce and apply a validity measure in credit scoring that is based on the total cost of misclassification. Specifically, we use comprehensive data from the annual financial statements of a sample of German companies and analyze the total cost of misclassification by comparing a generalized linear model and a generalized additive model with regard to their ability to predict a company's probability of default. On the basis of these data, the validity measure we introduce shows that, compared to generalized linear models, generalized additive models can reduce substantially the extent of misclassification and the total cost that this entails. The validity measure we introduce is informative and justifies the argument that generalized additive models should be preferred, although such models are more complex than generalized linear models. We conclude that to balance a model's validity and complexity, it is necessary to take into account the total cost of misclassification.     

水下航行器附连水质量的理论及实验研究

以二维无限长圆柱在水下的垂向振动为例,对其有限区域的不可压缩流场进行分析;通过数值计算并借鉴刘易斯法,分析了水域宽度比、水深比和浸没深度比等无量纲参数对刚体附连水质量的影响;提出了水下航行器附连水质量的快速预测公式.结果表明:刚性壁面可使刚体的附连水质量增大,但当刚体与壁面的距离增加到一定程度(截面半径的5倍)时,刚性壁面的影响可以忽略;自由表面可使刚体的附连水质量减小,当刚体与自由表面的距离达到截面半径的6倍时,可以忽略自由表面的影响;当刚体的垂向运动频率较高或刚体与自由表面的距离较大时,可以认为自由表面的速度势为零.     

An Adaptive Multiscale Ensemble Learning Paradigm for Nonstationary and Nonlinear Energy Price Time Series Forecasting

For forecasting nonstationary and nonlinear energy prices time series, a novel adaptive multiscale ensemble learning paradigm incorporating ensemble empirical mode decomposition (EEMD), particle swarm optimization (PSO) and least square support vector machines (LSSVM) with kernel function prototype is developed. Firstly, the extrema symmetry expansion EEMD, which can effectively restrain the mode mixing and end effects, is used to decompose the energy price into simple modes. Secondly, by using the fine‐to‐coarse reconstruction algorithm, the high‐frequency, low‐frequency and trend components are identified. Furthermore, autoregressive integrated moving average is applicable to predicting the high‐frequency components. LSSVM is suitable for forecasting the low‐frequency and trend components. At the same time, a universal kernel function prototype is introduced for making up the drawbacks of single kernel function, which can adaptively select the optimal kernel function type and model parameters according to the specific data using the PSO algorithm. Finally, the prediction results of all the components are aggregated into the forecasting values of energy price time series. The empirical results show that, compared with the popular prediction methods, the proposed method can significantly improve the prediction accuracy of energy prices, with high accuracy both in the level and directional predictions.

Novelty,coherence, and Mendeleev’s periodic table

Predictivism is the view that successful predictions of “novel” evidence carry more confirmational weight than accommodations of already known evidence. Novelty, in this context, has traditionally been conceived of as temporal novelty. However temporal predictivism has been criticized for lacking a rationale: why should the time order of theory and evidence matter? Instead, it has been proposed, novelty should be construed in terms of use-novelty, according to which evidence is novel if it was not used in the construction of a theory. Only if evidence is use-novel can it fully support the theory entailing it. As I point out in this paper, the writings of the most influential proponent of use-novelty contain a weaker and a stronger version of use-novelty. However both versions, I argue, are problematic. With regard to the appraisal of Mendeleev’ periodic table, the most contentious historical case in the predictivism debate, I argue that temporal predictivism is indeed supported, although in ways not previously appreciated. On the basis of this case, I argue for a form of so-called symptomatic predictivism according to which temporally novel predictions carry more confirmational weight only insofar as they reveal the theory’s presumed coherence of facts as real.
