As the number of objectives increases,the performance of the Pareto dominance-based Evolutionary Multi-objective Optimization( EMO) algorithms such as NSGA-II,SPEA2 severely deteriorates due to the drastic increase in the Pareto-incomparable solutions. We propose a sorting method which classifies these incomparable solutions into several ordered classes by using the decision maker's( DM) preference *** is accomplished by designing an interactive evolutionary algorithm and constructing convex cones. This method allows the DMs to drive the search process toward a preferred region of the Pareto optimal front. The performance of the proposed algorithm is assessed for two,three,and four-objective knapsack problems. The results demonstrate the algorithm ' s ability to converge to the most preferred point. The evaluation and comparison of the results indicate that the proposed approach gives better solutions than that of NSGA-II. In addition,the approach is more efficient compared to NSGA-II in terms of the number of generations required to reach the preferred point.

The active Sagaing fault in Myanmar defines the boundary between the Indian Plate and the Eurasian Plate and causes seismic damage in the major cities of Myanmar. Small bodies of serpentinite occur along the fault. We for the first time investigated the highly sheared serpentinite bodies in the Sheinmagar area and Yega Inn area along the Sagaing fault. Extensively sheared/brecciated serpentinites and related rocks, such as talc and/or chlorite-bearing rocks contains small rock fragments of serpentinites. Serpentine texture and mineral chemistry indicate that the protolith of these serpentinites were mainly harzburgite with minor amounts of dunite, some of which are cut by gabbroic veins. No shape-preferred orientation of the antigorite is present, indicating that the serpentinization was occurred under relatively static conditions. Protolith and serpentine minerals are similar to those of the jadeitite-bearing serpentinites in the north of the Sagaing fault(the Jade Mine belt). Chemical variations of spinels in the studied area are within the compositional range of forearc peridotites and those in the mantle section of nearby ophiolites. After the formation of antigorite serpentinite under static conditions, these serpentinites were subsequently, but locally deformed, probably due to the activity of the Sagaing fault, resulting in the formation of serpentinite schist/brecciated rock. The presence of the less-deformed antigorite serpentinite in the sheared/brecciated zone indicates the strain localization mainly along the surrounding serpentine-talc(±chlorite) schistose rocks, which is probably formed by the reaction between serpentinite and country rocks. Further studies are needed to better understand whether the distribution of serpentinized peridotites cause variations in the activity of the Sagaing fault.

随着互联网和通信技术(ICT)的进步,来自各种来源、模式或不同观点的海量数据不断涌现。例如,一个网页信息通常包含链接、文本、图像等,它也可以被视为不同的视图,这类数据通常被称为多视图数据。多视图聚类作为探索多视图数据的重要研究技术之一,近年来一直受到研究人员的关注,其也是流行的机器学习和无监督学习技术之一。现有的多视图聚类方法通常假设所有数据视图均为完整的。然而,该要求经常难以满足,因为在实际应用中某些视图往往无法收集所有的样本,从而形成了不完备多视图数据。自然地,不完备多视图数据聚类应运而生。不完备多视图聚类中的图构建对于实现聚类分析至关重要。但是,由于某些视图的样本缺失,无法构建完整的图来完全连接所有数据点。近年来,研究人员提出了多种基于不同方法的不完备多视图聚类方法。虽然这些方法对不完备多视图聚类有效且高效,但基于谱聚类的不完备多视图聚类算法仍然存在一定的缺陷和改进潜力需要进一步的改进和探索。针对不完备多视图聚类问题,本文的研究思路如下:首先,构建一个包含不完备多视图数据的所有视图的完整图进行聚类。其次,在学习图构造的表示时,引入索引矩阵来对所有视图的完整图和不完整图之间进行转换。此外,谱聚类用于学习所有视图共享的公共表示,并通过应用k-means算法获得更具区分性和紧凑性的公共表示。最后引入自适应权重向量,充分考虑不同视图的重要性权重,同时获得更具判别力的共识公共表示,从而达到聚类性能。本文以不完全多视图聚类为研究对象,提出以下研究成果:为了通过不完整或缺失信息的多视图数据构建完整图,并学习所有视图共享的公共表示,提出了一种基于自适应加权图融合的不完备多视图谱聚类(Incomplete Multiview Spectral Clustering based on Weighted Graph Fusion,IMSCGF),该算法可以应对各种不完整的多视图数据场景。所提出的方法可以同时将单视图图学习、融合图学习和谱聚类集成到一个统一的框架中,该框架能够通过不完整的图构建来学习所有视图共享的共识表示。通过预先构建k近邻,所提出的IMSCGF方法自适应学习所有视图的局部结构。然后,通过自动加权学习构建融合图,探索不同大小不完整图的一致性相似度矩阵,减少异常值的负面影响。在四个公共数据集上的实验结果表明,在大多数情况下,该方法比其他基线方法具有更高的准确性。针对不完备多视图聚类问题,进一步提出了自适应加权不完备多视图谱聚类(Adaptive Weighted Incomplete Multi-view Spectral Clustering,AWIMSC)算法,适用于处理多视图数据的完整和不完整情况。该方法考虑到由于每个视图的可用实例数量和特征维度的不同,每个视图的可用判别信息存在较大差异,从而导致每个视图的重要性不同。因此,为了衡量视图的重要性并提高聚类性能,本文在共识表示和亲和图矩阵学习的模型中加入了自适应权重学习。最后,在四个真实世界的数据集上进行了实验,实验结果表明了算法的有效性。本文设计了两种不完备多视图聚类算法,即基于加权图融合算法的不完备多视图谱聚类算法和自适应加权不完备多视图谱聚类算法。本文分析了两种算法的聚类性能和收敛性分析。通过与其他基线方法进行比较,对四个真实世界的数据集进行实验,所提出的方法在大多数情况下验证了有效性和优越性。

改革开放以来,中国国际地位迅速提高,以及中缅经济交往日益频繁,缅甸汉语教学也得到了快速的发展。目前在缅甸,不仅是华裔家庭的缅甸华人学习汉语,越来越多的非华裔缅甸人也开始学习汉语。而且,大部分缅甸华人与当地人同化了。于是,在缅甸,汉语成为华裔与非华裔的第二语言。①如今,中缅关系一直较好,但是为什么在缅甸还存在反华情绪?缅甸非华裔汉语学习者学习汉语时,是否认同中国文化?这种排华现象持续与学习汉语、认同中国文化是否产生矛盾?本文的第一章主要介绍研究缘起、选题意义与中国文化认同相关的文献综述。其中包括文化认同的界定,语言(二语/外语)教学领域的文化认同相关研究和汉语教学领域的文化认同相关研究,前人的研究成果与不足和本研究的主要内容和研究方法等。第二章阐释了缅甸汉语学习者中国文化认同调查问卷的设计,包括调查目的、调查对象的选取、问卷设计和调查过程。列出调查对象的基本信息后,分析调查对象学习汉语的动机和了解中国文化的方式。第三章为缅甸汉语学习者对中国文化认同分析。首先是对缅甸汉语学习者学习汉语的原因和学习中国文化的方式进行一个大概的阐述。其次,深入地进行缅甸汉语学习者对汉语的认同、对中国文化的认同、学习者感兴趣的文化内容和缅甸汉语学习者对中国人行为的分析。并对不同性别、不同民族、不同职业和不同汉语水平的缅甸汉语学习者在不同项目的认同方面进行了差异性分析。第四章分别为缅甸汉语学习者中国饮食、节日、艺术文化认同的分析与该项目的差异性分析。第五章论述缅甸汉语学习者中国文化认同的特点及应对策略。包括缅甸汉语学习者中国文化认同的特点及其原因分析和提升缅甸汉语学习者中国文化认同的策略。第六章对全文进行总结。研究者结合调查问卷与访谈,对缅甸仰光福星语言与电脑学苑孔子课堂与曼德勒孔教学校的中国文化教学进行了研究。研究基础上得出的结论利用SPSS分析,创新,并据此提出解决方案和建议。文章以缅甸汉语学习者的真实调查问卷为基础,再配合教师的访谈记录,然后运用文献分析法、访谈法、调查法、案例分析法等方式,同时使用SPSS软件进行统计分析。至今,在缅甸的汉语教学与中国文化认同的相关研究中,很少有人使用SPSS软件进行统计分析,因此这也是本文在缅甸汉语教学、中国文化认同研究方法上的一个创新。本文的创新点在于:选题新颖,首次对缅甸汉语学习者中国文化认同进行调查研究。其次,本文通过大量的调查访谈,分析出缅甸汉语学习者对中国文化认同的现状,并分析出不同性别、不同民族、不同职业和不同汉语水平的缅甸汉语学习者对汉语和中国文化的态度、感兴趣的文化内容、对中国文化的认同方式等方面存在的差异性,这些差异性分析皆可对日后的研究有一定的启发性。除此之外,研究缅甸汉语学习者对中国文化认同情况的文章目前还非常少,因此,本文的选题可说较为新颖。然而,笔者还针对缅甸汉语学习者对中国文化认同现状提出建议,希望为日后的研究提供借鉴与参考。
