查询词典 uncertain

At the early 1980s, is an effective mathematic tool to deal with the uncertain or fuzzy knowledge. Rough rule theory has been widely used in information retrieval, digital library, software engineering and knowledge discovery. Its main idea includes acquisition of rough decision rules by reduction of data under the condition of keeping an invariability of classification capacity. And it basically represents a concept by a pair of approximation sets according to the partition on the given data based on the indiscernibility relation. Rough sets theory is well suited to deal with inconsistency of the rough approximations. So it is a new mathematical tool dealing with vagueness and uncertainty, and has found its applications in many areas such as AI, KDD, pattern recognition and classification and fault diagnosis.

主要完成了以下几个方面的工作：(1)对于高速移动机器人车道线跟踪问题中的规则知识获取，首先阐述了模糊逻辑系统的基本特点、工作原理和基本作法，分析了模糊规则知识获取过于依赖专家经验知识、对于每一个细节几乎都需要人工主观经验的参与、难以处理大数据集样本等方面的不足，进而阐述了粗糙集合理论的基本特点、基于粗糙集合理论的规则获取的关键技术和工作原理，为后续章节中经典粗糙集合模型的扩展及粗糙决策规则集的性能分析做好基础；(2)在经典粗糙集理论及其一般扩展的可变精度粗糙集VPRS的基础上，提出了非均匀可变精度粗糙集模型k-VPRS。

My demonstration is focused on her two major conundrums of identity: gender and nationality. Firstly, she had been not confirmed her gender as conventionally and socially acknowledged female. She was a put-on woman, both bisexual and masculine. Her psychological trauma resulted from this everlasting confusion in gender. Secondly, her national identity remained uncertain. Though born in New Zealand, she was more Londonish than native spiritually.

对于曼斯菲尔德来说，她的两大身份标志并不明确：一是她的女性身份，她有明显的同性恋倾向以及男性气质，与约定俗成的女性身份界定不符；另一个是她的国家身份，曼斯菲尔德并非英国殖民地——新西兰的土著，她的祖父来自伦敦，曼斯菲尔德自己作家身份的确立也是在伦敦完成的，但是后来成为她大部分小说题材的是她在新西兰度过的童年，这种身份的不确定性必然影响了曼斯菲尔德的个性稳定以及心灵健康。
