Artificial neural networks with feature transformation based on domain knowledge for the prediction of stock index futures

A feature transformation method based on domain knowledge for arti?cial neural networks (ANNs) is proposed. The method of feature transformation based on domain knowledge converts continuous values into discrete values in accordance with the knowledge of experts in speci?c application domains. This approach effectively ?lters data, trains the classi?er, and extracts the rules from the classi?er. In addition, it reduces the dimensionality of the feature space, which not only decreases the cost and time in the operation but also enhances the generalizability of the classi?er. The experimental results of the proposed approach will be compared and tested statistically with the results of the linear transformation method. The results show that the method of feature transformation based on domain knowledge outperforms the linear transformation in modelling of ANNs. Copyright © 2004 John Wiley & Sons, Ltd.     

The service sector of Cuba: An analysis and critique

The Cuban economy has experienced a significant increase in foreign direct investment over the past decade due to the end of the Soviet Union and the establishment of more liberal trade policies. Although the U.S. embargo of trade with Cuba still exists, there has been movement lately that suggests the end of the four‐decades‐old policy. The purpose of this article is to analyze the current Cuban business environment and to identify potential entrepreneurial opportunities in the service sector. Major trade partners are also reviewed and managerial implications discussed. © 2006 Wiley Periodicals, Inc.

云南旅游品牌发展与对策分析

随着国际国内旅游市场竞争的日益激烈,我们应该意识到,旅游市场之争实质上是品牌之争。云南旅游业应该在充分认识自身旅游品牌发展存在的问题基础上,找出问题,寻求改进的措施,从简单的资源要素竞争转化为品牌经营竞争战略,不断地进行品牌建设和品牌创新,实现从旅游品牌到旅游名牌的飞跃。     

机场净空区超高障碍物风险性分析

针对机场净空区超高障碍物较多的现象,对飞机飞行航迹进行了测试,提出了净空安全系数的概念,结合实际测试数据,应用统计分析原理,得出了净空安全系数的概率分布规律.以安全系数的分布规律为基础,对不同超高障碍物的风险性进行了分析,并提出了按照不同安全系数划分障碍物限制高度的思路,最后给出了不同类型机场净空安全系数的建议值,对各类机场净空管理和障碍物限制面的确定具有重要参考价值.     

经济增长、收入分配对农村贫困变动的影响

文章利用了基于Lorenz曲线进行贫困测度及其分解的方法,实证研究了1985～2003年中国农村的贫困变动,以及经济增长和收入分配对贫困变动的影响.结果表明,经济增长使农村居民收入增加,大幅度减少了贫困,但农村居民的收入差距逐渐拉大,收入不平等加剧部分地抵消了经济增长的减贫成效.     

This is what the leading indicators lead

We propose an optimal filter to transform the Conference Board Composite Leading Index (CLI) into recession probabilities in the US economy. We also analyse the CLI's accuracy at anticipating US output growth. We compare the predictive performance of linear, VAR extensions of smooth transition regression and switching regimes, probit, non‐parametric models and conclude that a combination of the switching regimes and non‐parametric forecasts is the best strategy at predicting both the NBER business cycle schedule and GDP growth. This confirms the usefulness of CLI, even in a real‐time analysis. Copyright © 2002 John Wiley & Sons, Ltd.
