Abstract

In this paper, we introduce an end-to-end generative adversarial network (GAN) based on sparse learning for single image blind motion deblurring, which we called SL-CycleGAN. For the first time in blind motion deblurring, we propose a sparse ResNet-block as a combination of sparse convolution layers and a trainable spatial pooler k-winner based on HTM (Hierarchical Temporal Memory) to replace non-linearity such as ReLU in the ResNet-block of SL-CycleGAN generators. Furthermore, unlike many state-of-the-art GAN-based motion deblurring methods that treat motion deblurring as a linear end-to-end process, we take our inspiration from the domain-to-domain translation ability of CycleGAN, and we show that image deblurring can be cycle-consistent while achieving the best qualitative results. Finally, we perform extensive experiments on popular image benchmarks both qualitatively and quantitatively and achieve the record-breaking PSNR of 38.087 dB on GoPro dataset, which is 5.377 dB better than the most recent deblurring method., Comment: 12 pages

Abstract

This paper presents a novel context-aware image denoising algorithm that combines an adaptive image smoothing technique and color reduction techniques to remove perturbation from adversarial images. Adaptive image smoothing is achieved using auto-threshold canny edge detection to produce an accurate edge map used to produce a blurred image that preserves more edge features. The proposed algorithm then uses color reduction techniques to reconstruct the image using only a few representative colors. Through this technique, the algorithm can reduce the effects of adversarial perturbations on images. We also discuss experimental data on classification accuracy. Our results showed that the proposed approach reduces adversarial perturbation in adversarial attacks and increases the robustness of the deep convolutional neural network models., Comment: 5 pages, 3 figures, 1 table

8. A Longitudinal Investigation of Secondary School Achievement Using Group-Based Trajectory Modeling

Author

Fu, Yuan Chih, Lee, Hsiu Ming, Wang, Li-yun, and Chen, Sheng Lee

Abstract

In this study, we investigate the growth trajectory of 519 students in a vocational senior high school in Taiwan. The group-based trajectory model identifies 3 subgroups with distinct trajectories of academic achievement in Math and English. This study reveals baseline predictive factors associated with these trajectories as well as relationships between different trajectories and students' college entrance examination scores. Our analysis contributes to the literature in two ways. First, this study shows that when school practices focus on improving the performance of students in the low achievement group, the performance of those in the middle is sacrificed. Second, upon their enrollment, students in the low achievement group appear to have significantly lower academic preparation and educational aspirations.

16. Higher Education Institutional and Program Evaluations in Taiwan and the Emerging Roles of Higher Education Evaluation and Accreditation Council of Taiwan (HEEACT)

Author

Lee, Lung-Sheng, Wei, Yen-Shun, and Wang, Li-Yun

Abstract

Post-secondary education institutions in Taiwan are divided into two tracks, general higher education (HE) and technological and vocational education (TVE). The evaluation of all universities/colleges is mandated by the University Act. Higher education institutions receive mandated institutional evaluation every six years and program evaluation every five years. The purpose of this paper is to briefly introduce the status of higher education institutional and program evaluations in Taiwan as well as the emerging roles of the Higher Education Evaluation and Accreditation Council of Taiwan (HEEACT). Both institutional and program evaluations are accreditation-oriented, adopting the PDCA (Plan-Do-Check-Act) cycle with an emphasis on institutional and program self-positioning, student learning outcome, and mechanism for continuous improvement. As the third-party planner and implementer of higher education institutional and program evaluations, HEEACT has conducted internal and external assessments as well as entrusted third-party meta-evaluation to assure its quality of work. Faced with the emerging challenges, such as the Ministry of Education's new policy on requiring some universities/colleges to implement self-conducted external evaluation in replacement of the third-party program evaluation, HEEACT has to alter its roles and becomes a Critical Friend of higher education institutions and programs, a Change Agent of higher education institutional and program evaluation, and an Effective Facilitator of the international exchanges and cooperation on quality assurance and mutual recognitions of national qualifications.

17. Higher Educational Expansion in Taiwan from 1950 to 1994: Patterns and Explanations. ASHE Annual Meeting Paper.

Author

Wang, Li-yun

Abstract

This paper examines the expansion of higher education in Taiwan from 1950 to 1994, looking first at the patterns of the expansion and, secondly, attempting to account for these patterns. Higher education in Taiwan is defined as general universities and colleges, institutes of technology, and junior colleges with governance of the system under the control of the Ministry of Education. The study reviewed major historical events and examined documents and the literature concerning patterns of expansion in the number of institutions, in the number of students enrolled, and in expenditures. The study then reviewed the state's stated reasons--economic concerns, educational quality, social demands, and equal distribution of resources--for regulating expansion of higher education, and compared these reasons with other models of educational expansion and with the actual results achieved. The paper concludes by taking issue with the state's official position and suggests that the primary reason for its controlling growth was to keep unemployment rates among college graduates low. Further studies to examine educational policy making and educational supply and demand models are suggested. Appendices illustrate the structure of the Taiwan school system, list historical events related to higher educational expansion, list official documents reviewed, and provide graphical displays of trend data.

28. Pursuing Quality and Equity of Higher Education: A Review of Policies and Practices in East Asia

Author

Peng, Samuel S. and Wang, Li-Yun

Abstract

The condition of higher education is an important indicator of a nation's competitiveness in the modern knowledge-based world economy. Higher education builds up a nation's human resources by equipping students with advanced knowledge, professional skills, and critical and creative thinking ability. Higher education institutions are significant, thriving places where new knowledge and technology, which are both underwriters and catalysts for a nation's economic growth and competitiveness, are generated. For these reasons, over recent decades most nations around the world have devoted great efforts to development of their higher education systems. East Asia is a case in point. Its higher education system has been greatly expanded since World War II and the results are impressive, as reflected in the growth in the number of private colleges and universities. However, expansion of higher education has raised some new issues, which are discussed in this article. To address these issues, East Asian governments as well as individual institutions have initiated various policies and reform programs in recent years. This article presents a review of those policies and programs.

Abstract

Wang Y, Tian F, Yan M, et al. Drug Des Devel Ther. 2016;10:1743–1751. At the authors request, the Editor and Publisher of Drug Design, Development and Therapy wish to retract the published article. Previous concerns had been raised to the authors regarding the alleged duplication of images in Figures 1A-b and 1A-c and a corrigendum had been published. More recently, concerns have also been raised to the authors regarding the alleged duplication of images between Figure 2A-b and 2A-e. In addition, there were also concerns raised regarding the duplication of certain features between several images from Figures 2 and 3. The journal wishes to recognize that these particular concerns were introduced during the publication process and were not introduced by the authors. However, in relation to the duplication of images between Figure 2A-b and 2A-e, the authors have acknowledged this. The authors were able to provide original data to the journal, but it was unable to support the integrity of the research and the authors requested to retract the article and the Editor agreed with this. Our decision-making was informed by our policy on publishing ethics and integrity and the COPE guidelines on retraction. The retracted article will remain online to maintain the scholarly record, but it will be digitally watermarked on each page as “Retracted”.
