Improved Imbalanced Classification with CCCD and its Variants
No full textWe use a graph based classification method called class cover catch digraphs (CCCDs) to solve class cover problem. CCCD is a random graph model gives graph solution to calss cover problem and shows relatively good performance in class imbalance problem. We will focus on the improvement of CCCD performance. Ensemble methods bagging and boosting will be employed to modify CCCD. We show and compare the performance of the ensemble CCCD classifiers with other commonly used classifiers by Monte Carlo simulation analysis.
From the results, CCCDs are very robust to imbalanced data. We tested ensemble with Different Parameters. When dealing with local imbalanced data, ensembling can slightly improve the the performance of P-CCCD and RW-CCCD in all dimensions setting while E-Comb
showed the best performance among all classifiers. When dealing with local balanced data, ERW-CCCD showed slightly better performance in low dimensions. Both EP-CCCD and ERW-CCCD showed poor performance in high dimensions but E-Comb showed better performance
when dimension increased. E-Comb also showed a relatively stable performance among all methods. Bagging can significantly improve the performance of CCCD when dealing with local imbalanced dataset but it does not show much improvement when dealing with local balanced dataset

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
