In this paper, we have analyzed the determinants of the capital structure of Chinese listed companies, especially, considered the non-tradable share reform to the influence of capital structure. The investigation has been performed using panel data procedure for a sample of 402 Chinese companies listed on the Shanghai Stock Exchange over the span from 2004 to 2006. The regression results show that,...
Decision tree construction is a well-studied problem in data mining. Recently, there has been much interest in mining data streams. Domingos and Hulten have presented a one-pass algorithm for decision tree constructions. Their system using Hoeffding inequality to achieve a probabilistic bound on the accuracy of the tree constructed. In this paper, we revisit this problem and propose a decision tree...
As digital video data becomes more pervasive, mining information from multimedia data becomes increasingly important. Although researches in multimedia mining area have shown great potential in daily life, the huge computational requirement prohibits its wide use in practice. Since our personal computer is shifting from uniprocessors to multicore processors, exploiting thread level parallelism in...
As video data become more and more pervasive, mining information from multimedia data sources becomes increasingly important, e.g., automatically extracting highlights from soccer game video content. However, the huge computation requirement of mining interested data limits its wide use in practice. Since the hardware imperative behind computer architecture is shifting from uniprocessors to multi-core...
As digital video data becomes more pervasive, mining information from multimedia data becomes increasingly important, e.g., extraction of goal events in soccer game automatically from the video content. Though all of these advances in multimedia mining have shown great potential in daily life, the huge computational requirement prohibits its wide use in practice. As computer architecture evolves from...
As multi/many core processors become prevalent, programming language is important in constructing efficient parallel applications. In this work, we build a multithreaded video mining application with Java, examine the thread profiling information and micro-architecture metrics to identify the factors limiting the scalability, and employ a number of ways to improve performance. Besides, we conduct...
This paper studies the data weighting affection of rules that derived from different decision tree algorithms. The data that we study is collected from patients with coronary heart disease; it has 1723 records and 71 attributes in each record. The weighting methods we used are system reconstruction method and principle component analysis, from which we get two weighted data sets. The analysis based...
