File semantic has proven effective in optimizing large scale distributed file system. As a consequence of the elaborate and
rich I/O interfaces between upper layer applications and file systems, file system can provide useful and insightful information
about semantic. Hence, file semantic mining has become an increasingly important practice in both engineering and research
community. Unfortunately, it is a challenge to exploit file semantic knowledge because a variety of factors could affect this
information exploration process. Even worse, the challenges are exacerbated due to the intricate interdependency between these
factors, and make it difficult to fully exploit the potentially important correlation among various semantic knowledges. This
article proposes a file access correlation miming and evaluation reference (FARMER) model, where file is treated as a multivariate
vector space, and each item within the vector corresponds a separate factor of the given file. The selection of factor depends
on the application, examples of factors are file path, creator and executing program. If one particular factor occurs in both
files, its value is non-zero. It is clear that the extent of inter-file relationships can be measured based on the likeness
of their factor values in the semantic vectors. Benefit from this model, FARMER represents files as structured vectors of
identifiers, and basic vector operations can be leveraged to quantify file correlation between two file vectors. FARMER model
leverages linear regression model to estimate the strength of the relationship between file correlation and a set of influencing
factors so that the “bad knowledge” can be filtered out. To demonstrate the ability of new FARMER model, FARMER is incorporated
into a real large-scale object-based storage system as a case study to dynamically infer file correlations. In addition FARMER-enabled
optimize service for metadata prefetching algorithm and object data layout algorithm is implemented. Experimental results
show that is FARMER-enabled prefetching algorithm is shown to reduce the metadata operations latency by approximately 30%–40%
when compared to a state-of-the-art metadata prefetching algorithm and a commonly used replacement policy. 相似文献

Hilbert-Huang transform method has been widely utilized from its inception because of the superiority in varieties of areas.
The Hilbert spectrum thus obtained is able to reflect the distribution of the signal energy in a number of scales accurately.
In this paper, a novel feature called ECC is proposed via feature extraction of the Hilbert energy spectrum which describes the distribution of the instantaneous energy. The experimental
results conspicuously demonstrate that ECC outperforms the traditional short-term average energy. Combination of the ECC with
mel frequency cepstral coefficients (MFCC) delineates the distribution of energy in the time domain and frequency domain,
and the features of this group achieve a better recognition effect compared with the feature combination of the short-term
average energy, pitch and MFCC. Afterwards, further improvements of ECC are developed. TECC is gained by combining ECC with
the teager energy operator, and EFCC is obtained by introducing the instantaneous frequency to the energy. In the experiments,
seven status of emotion are selected to be recognized and the highest recognition rate 83.57% is achieved within the classification
accuracy of boredom reaching 100%. The numerical results indicate that the proposed features ECC, TECC and EFCC can improve
the performance of speech emotion recognition substantially. 相似文献

辛亥革命的动力是由革命党、立宪派、统治集团内部改革派等多种力量组成的反清阵营,立宪派压抑党人,袁世凯迫孙让位应视为阵营内部的斗争,不能作为失败的依据。立宪派"保路"引发武昌起义,策动"独立"促进清朝统治的瓦解,袁氏集团拥护"共和"迫使清廷退位,革命阵营扩大恰与胜利同行。辛亥革命的目标可以理解为"主体预设"和"后人规定"等多层任务,要求彻底完成后人规定的反帝反封建任务,违背了历史主义原则,据此不足以证明其失败。辛亥革命基本完成了主体预设的三民主义,也参与了反帝反封建的任务,表明了胜利。辛亥革命付出代价决定于专制的顽固与满汉之间的对峙,革命后的割据根源在于封建经济与列强干预,代价与混战也不能证明失败。革命促进了政治体制、经济基础与文化意识的进步,受益大于成本,再次印证胜利。 相似文献

采用问卷法对351名艺术类大学生进行调查,探讨艺术类大学生情绪调节策略特点及其与人格、自动思维的相互关系.结果表明:(1)艺术类大学生在情绪调节策略使用上性别差异不显著;在愤怒和悲伤两种消极情绪调节策略中,注意转移策略最多.前者的情境修正策略最少,后者的人际支持策略最少.表达抑制策略在两种情绪调节中的使用均较少;在快乐情绪调节策略中,支持分享策略使用最多,表达抑制最少.(2)人格特质P、N和L及自动思维与情绪调节策略关系密切;(3)人格特质P,或通过自动思维对情绪调节策略有直接和间接效应. 相似文献

儿童哲学的诞生缘于20世纪60年代对话哲学与"批判性思维"运动的兴起.我国有近三十年的儿童哲学研究,相比于前二十年的研究,近十年的研究显得更为"理智",在引进、介绍、实验的同时,研究者开始对儿童哲学研究的方向和内容进行审视,寻找儿童哲学与中国教育改革的契合之路. 相似文献
