Validation assessments on resampling method in imbalanced binary classification for linear discriminant analysis

The analysis on the location and dispersion statistics of the performance measures was further enlightened on: (i) the effect of a resampling method on the performance of LDA, and (ii) the enhancement in the learning fairness of LDA on objects regardless of sample size, hence reducing the effect of the curse of class imbalance.

Analysis of trends related to Vietnam in Korea

As more Koreans invested in Vietnam, the number of foreign students in Korea increased due to the perception that studying in Korea would be beneficial for employment within Vietnam. Also, the ratio of international students entering graduate school is increasing. In this study, the researches related to Vietnam were investigated, focusing on the articles and papers of journals searched through the Vietnam keyword of the National Assembly Library. We also have examined research trends through Big Data Analysis.

Analyzing the field of bioinformatics with the multi-faceted topic modeling technique

Bioinformatics is an interdisciplinary field at the intersection of molecular biology and computing technology. To characterize the field as convergent domain, researchers have used bibliometrics, augmented with text-mining techniques for content analysis. In previous studies, Latent Dirichlet Allocation (LDA) was the most representative topic modeling technique for identifying topic structure of subject areas.
