查询词典 discriminative

This approach first aligned 3D faces based on non-uniform mesh re-sampling which result the uniform number of vertex and topology structure and kept in a vector. Second, we changed the vector to the matrix by division and overlap, and then 2DLDA suggests a feature selection strategy to select the most discriminative features from the corner.

该算法首先使用基于非均匀网格重采样的方法对所有三维人脸做规格化处理，使三维人脸具有统一的点数和拓扑结构；其次，以先分段、再重叠的形式将原本一维向量表示组织为二维矩阵表示，然后使用二维线性判别分析方法(2DLDA)对获得的数据进行特征抽取。

In order to decrease the error rate of speech recognition, speaker adaptation techniques are often used to adjust speaker-dependent acoustic models. MLLR (Maximum Likelihood Linear Regression) and MAP are two of the most popular techniques in recent years. MLLR uses the technique of regression trees. It calculates the transform matrix for each leaf node of the tree. This makes it possible to use fewer sentences to decrease the error rate of HMM-based speech recognition. However, while we examined the recognition result, we found that although the overall error rate decreased, but the error rate of certain confusable phones was higher. In order to solve this problem, we propose the use MPE (Minimum Phone Error Discriminative Training) to solve this problem.

在语音辨识技术的实际应用上，语者调适技术常被用做调整语者无关之声学模型，使其对於特定语者之辨识率有所提升，常见的语者调适技术有最大化相似度线性回归（Maximum Likelihood Linear Regression），其精神在於透过对语音辨识模型相近的mixture做群聚，再对各个群聚做调整，以期能达到利用少量语料，提升辨识率的目的，但其缺点为，在发音上相近的模型，其mixture原本就极为近似，若再分类为同一群聚做调整，容易因为使用者的发音习惯，而使模型偏向ㄓ或ㄗ，因此虽然整体的辨识率获得提升，但却造成混淆音的错误率上升。

In Chinese, qualitative adjectives and their discriminative and restrictive features constitute an unmarked match, and stative adjectives and their depictive and non-restrictive features do another.

本文针对MS跟踪和粒子滤波跟踪各自的优缺点，将其两者进行了很好地结合，提出了两步跟踪算法，其特点有：保留了MS跟踪实时性的优点的同时，也具有粒子滤波在遮挡情况下的鲁棒性等特点；在所需的每步粒子跟踪中，以上一步的跟踪结果与模板的相似度为先验知识，自适应地选取粒子个数和传播半径，缓解了粒子缺乏多样性的缺点，也根据这个相似度来判断是否需要对目标模板的更新，保证了更新的有效性。

If be opposite not carefully,this is meant vein sex is impotent try the cent vein leakage that is aimed at different type uses different operation kind to cannot obtain better curative effect, did not add discriminative land in the past alone ligate carries deep vein on the back to fail to obtain ideal curative effect also is at that time the inevitable result of people understanding superficial.

In order to analyze the reason for a flawed Iraqi identity, this article delaminates the internal identity of Iraq to two levels——national and sub-national, further distinguishes familial identity, religional identity and ethnic identity on the sub-national level, and studies the relations between national and sub-national identities with looking back at the momentous events in Iraqi history, consequently finds the different influences that various of sub-national identities react on the formation of Iraqi national identity and how the discriminative internal policy intensified sub-national identities, and then builds a theoretical framework with two dimensions from upwards and downwards to explain the reason for unshaped Iraqi national identity.

为了分析伊拉克国家认同没有形成的原因，文章将伊拉克内部认同在国家和次国家两个层次上进行划分，并进一步区分了次国家认同中的家族部落、宗教派系、族群这三个认同类型，然后以国家认同和次国家认同的关系为切入点，研究了伊拉克历史上的几个重大事件，发现了各次国家认同对国家认同的形成具有不同程度的影响，其中族群认同对国家认同形成的破坏作用最大；与此同时，伊拉克前政府歧视性的内部政策强化了各次国家认同，是造成伊拉克国家认同没有形成的另一个原因，从而从上、下两个维度解释伊拉克国家认同未形成原因的理论架构。
