文本情感分析是当前网络舆情分析、产品评价、数据挖掘等领域的重要任务。由于当前网络数据的急剧增长,依靠人工设计特征或者传统的自然语言处理语法分析工具等进行分析,不但准确率不高而且费时费力。而传统的卷积神经网络模型均未考虑句子的结构信息,并且在训练时很容易发生过拟合。针对这两方面的不足,使用基于深度学习的卷积神经网络模型分析文本的情感倾向,采用分段池化的策略将句子结构考虑进来,分段提取句子不同结构的主要特征;并且引入Dropout算法以避免模型的过拟合和提升泛化能力。实验结果表明,分段池化策略和Dropout算法均有助于提升模型的性能,所提方法在中文酒店评价数据集上达到了91%的分类准确率,在斯坦福英文情感树库数据集五分类任务上达到了45.9%的准确率,较基线模型都有显著的提升。

Two case reports of gastroendoscopy-associated Acinetobacter baumannii bacteremia

引用

World Journal of Gastroenterology 2013年第18期19卷 2835-2840页

作者： chang-Hua Chen shun-Sheng Wu Chieh-Chen huang Section of Infectious Diseases Department of Internal Medicine Changhua Christian Hospital Changhua 500 Taiwan Section of Gastroenterology Department of Internal Medicine Changhua Christian Hospital Changhua 500 Taiwan Department of Life Science College of Life Science National Chung Hsing University Taichung 402 Taiwan

Two cases of gastroendoscopy-associated Acinetobacter baumannii (A. baumannii ) bacteremia were discovered at the study hospital. The first case was a 66-year-old woman who underwent endoscopic retrograde cholangiopancreatography and endoscopic retrograde papillotomy, and then A. baumannii bacteremia occurred. The second case was a 70-year-old female who underwent endoscopic retrograde biliary drainage due to obstruction of intra-hepatic ducts, and bacteremia occurred due to polymicrobes (Escherichia coli , viridans streptococcus , and A. baumannii ). After a literature review, we suggest that correct gastroendoscopy technique and skill in drainage procedures, as well as antibiotic prophylaxis, are of paramount importance in minimizing the risk of gastroendoscopy-associated bacteremia.

Isolation of a Mutant of Ferl Gene, Acting Synergistically with the ARF8 Gene to Control Development of the Anther and Filament in Arabidopsis

引用

Journal of Integrative Plant Biology 2005年第3期47卷 327-333页

作者： chang-EnTIAN shun-ZhiLIU KotaroYAMAMOTO DepartmentofBioengineering SchoolofBiologicalandChemicalEngineeringGuangzhouUniversityGuangzhou510405China／／DivisionofB DepartmentofBioengineering SchoolofBiologicalandChemicalEngineeringGuangzhouUniversityGuangzhou510405China DivisionofBiologicalSciences GraduateSchoolofScienceHokkaidoUniversitySapporo010-0810Japan

Auxin response factors (ARFs) play a central role in plants as transcriptional factors in response to auxin. The Arabidopsis ARF8 gene is a light-inducible gene and ARF8 protein might control auxin homeostasis in a negative feed-back fashion through regulation of GH3 gene expression. In a double mutant designated infertile line including arf8-1 (a T-DNA insertion mutant of ARF8), we isolated fertility1-1 (fer1-1), a mutant of Fer1, which acts synergistically with ARF8 to control the development of the anther and filament in Arabidopsis. Genetics analysis has demonstrated that fer 1-1 is a T-DNA insertion line, indicating that Fer1 might be cloned by inverse polymerase chain reaction (PCR) or the TAIL-PCR approach. Phenotypic identification and molecular analysis of fer 1-1 and the infertile line will be helpful to characterize the function of Fer1, to further study the function of ARF8, and to reveal the molecular mechanism underlying the interaction of Fer1 and ARF8 in controlling development of the anther and filament.

A Robust Algorithm for Blind Total Variation Restoration

引用

Acta Mathematicae Applicatae Sinica 2008年第4期24卷 681-690页

作者： Jing Xu Qian-shun chang School of Statistics and Mathematics Zhejiang Gongshang University Hangzhou 310018 China Academy of Mathematics and Systems Science Chinese Academy of Sciences Deijing 100190 China

Image restoration is a fundamental problem in image processing. Blind image restoration has a great value in its practical application. However, it is not an easy problem to solve due to its complexity and difficulty. In this paper, we combine our robust algorithm for known blur operator with an alternating minimization implicit iterative scheme to deal with blind deconvolution problem, recover the image and identify the point spread function（PSF）. The only assumption needed is satisfy the practical physical sense. Numerical experiments demonstrate that this minimization algorithm is efficient and robust over a wide range of PSF and have almost the same results compared with known PSF algorithm.

New Time Dependent Pretreat Models Based on Total Variational Image Restoration

Acta Mathematicae Applicatae Sinica 2011年第1期27卷 129-140页

作者： Jing Xu Qian-shun chang School of Statistics and Mathematics Zhejiang Gongshang University Hangzhou 310018 China Division of Mathematical Sciences School of Physical and Mathematical Sciences Nanyang TechnologicalUniversity 50 Nanyang Avenue Singapore 639798 Academy of Mathematics and Systems Science Chinese Academy of Sciences Beijing 110190 China

In this paper, we propose new pretreat models for total variation （TV） minimization problems in image deblurring and denoising. Specially, blur operator is considered as useful information in restoration. New models in form is equivalent to pretreat the initial value by image blur operator. We successfully get a new （L. Rudin, S. Osher, and E. Fatemi） ROF model, a new level set motion model and a new anisotropic diffusion model respectively. Numerical experiments demonstrate that, under the same stopping rule, the proposed methods significantly accelerate the convergence of the toothed, save computation time and get the same restored effect.

GAUSS-SEIDEL-TYPE MULTIGRID METHODS

引用

Journal of Computational Mathematics 2003年第4期21卷 421-434页

作者： Zhao-hui huang Qian-shun chang (Academy of Mathematics and System Sciences, Chinese Academy of Sciences, Beijing 100080, China) Academy of Mathematics and System Sciences Chinese Academy of Sciences Beijing 100080 China

By making use of the Gauss-Seidel-type solution method, the procedure for computing the interpolation operator of multigrid methods is simplified. This leads to a saving of computational time. Three new kinds of interpolation formulae are obtained by adopting different approximate methods, to try to enhance the accuracy of the interpolatory operator. A theoretical study proves the two-level convergence of these Gauss-Seidel-type MG methods. A series of numerical experiments is presented to evaluate the relative performance of the methods with respect to the convergence factor, CPU-time(for one V-cycle and the setup phase) and computational complexity.
