Extraction of novel features for emotion recognition

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.

马克思主义的"守夜人" --阿尔都塞的理论解读

阿尔都塞甘当马克思主义的"守夜人",全身心投入到重新解读马克思的理论活动中,其思想初衷是要在马克思主义与非马克思主义之间"划一条分界线",坚守马克思理论发现的科学特性."回归马克思",更准确地说是"回归成年马克思",构成了阿尔都塞理论解读的逻辑线索.有了结构主义和精神分析学的强力介入,阿尔都塞的理论解读不可避免地打上了这些时尚精神的烙印.他对马克思的全新解读,是把马克思描绘成一个不自觉的结构主义者,让马克思穿上了"理论反人道主义"的外衣.崭新的方法和概念,展现了一个全新的马克思的形象.这种解读着实给马克思主义的理论研究带来了一股难得的清风,为如何发展马克思主义提供了一种有益的启示.     

怎样求函数EXP~((q))的可接受有理逼近

本文首先得到了函数R_(?)~s(q)是函数exp(q)的各类可接受有理逼近的必要条件,其次证明了exp(q)的含有s+t-p~*个自由参数的不低于p~*阶的有理逼近存在,且对于参数的每一组给定值,逼近式唯一.接着就逼近阶P≧2s-2,s≧2情形给出了exp(q)的双参数有理逼近R_s~s(q_ib_(s-1),b_s)和三参数有理逼近R_(s+1)~s(q_ib_(s-1),b_s,b_(s+1))的系数计算公式,并由此得到了求exp的含有多个自由参数的有理逼近的一般方法.

Critical Thinking and Educational Ideal

Critical thinking, as an educational trend, has been much discussed and proposed nowadays. In this paper, an analysis is made on the gap between our present educational practice and educational ideal from three different aspects, that is, the content, the manner and the one-sidedness of our teaching. It＇s observed that there is still a long way to go in order to realize our educational ideal and critical thinking, and critical pedagogy should be widely promoted and applied so as to foster well-educated people in its true sense. A conclusion is finally reached that education is the core no matter what theories and concepts are proposed and adopted.     

提高人的素质是促进两个文明建设的根本：－对外来人口教育与培训的思考

改革开放引发了全国人口大流动，大批农村富余劳动力涌入城市，为城市经济的建设和发展主入了生机和活力。但由于来外人口大多来自偏远落后地区，精神、化素质较差，因而也给城市经济的发展和社会的稳定带来了负面影响，因此，在对其加强管理的同时，也应从培训、教育的角度促使其自身素质的提高。高等学校做为育人阵地，应该充分发挥自己的办学优势，协同有关部门共同做好外来人口培训工作，为促进两个明建设做出自己的贡献。
