简介:扬声器适应测试正规化(ATnorm)是在文章无关的扬声器确认的广泛地使用的分数正规化的最有效的途径,它选择扬声器有一个额外的开发语料库的适应冒名顶替者队以便提高识别性能。在这份报纸,能在原来的ATnorm上提供全面重要优点的ATnorm的改进实现被介绍。这个方法在说话者采用新奇生气类似大小没有一个额外的发展语料库的适应的队模型选择。它能与原来的ATnorm完成可比较的表演并且中等减少计算复杂性。与保存额外的开发语料库的完整的使用,全面系统性能能显著地被改进。结果在这个方法在系统性能提供重要改进,这被显示出的NIST2006扬声器识别评估数据语料库上被介绍,与相对,14.4%逼近相等的错误率(无论何时),14.6%逼近总体上获得的决定费用功能(DCF)。

简介:用微数组技术的高产量的全球基因表示上的研究曾经产生了大量系统的transcriptome数据。在利用这些异构的数据集的主要挑战是怎么由内部试金的方法使表示侧面正常化。不同非线性、线性的正规化方法被开发了,它实质上依靠在二不同试金之间的真或察觉的对数的褶层变化分布在自然是对称的假设。然而,不对称的基因表达式变化经常被观察,导致非最优的正规化结果并且在后果潜在地到几千假调用。因此,我们明确地调查了不对称的比较transcriptome侧面并且为柔韧、全球的内部试金的正规化用指数的错误工作的加权的否定的秒顺序(NeONORM)开发了正规化。NeONORM高效地抑制规章的事件处理以便在正规化上最小化他们的似是而非的影响的真基因。我们用人工、真的试验性的数据集评估了NeONORM的适用性,哪个证明NeONORM能系统地被用于内部试金、内部条件的比较。
