Deep Scalogram Representations for Acoustic Scene Classification

IEEE/CAA Journal of Automatica Sinica 2018年第3期5卷 662-669页

作者： Zhao Ren Kun Qian Zixing Zhang Vedhas Pandit Alice Baird Bjorn Schuller ZD.B Chair of Embedded Intelligence for Health Care and Wellbeing University of Augsburg Germany Machine Intelligence and Signal Processing Group Technische Universitat Munchen Group on language Audio and Music (GLAM) Imperial College London UK IEEE

Spectrogram representations of acoustic scenes have achieved competitive performance for acoustic scene classification. Yet, the spectrogram alone does not take into account a substantial amount of time-frequency information. In this study, we present an approach for exploring the benefits of deep scalogram representations, extracted in segments from an audio stream. The approach presented firstly transforms the segmented acoustic scenes into bump and morse scalograms, as well as spectrograms; secondly, the spectrograms or scalograms are sent into pre-trained convolutional neural networks; thirdly,the features extracted from a subsequent fully connected layer are fed into(bidirectional) gated recurrent neural networks, which are followed by a single highway layer and a softmax layer;finally, predictions from these three systems are fused by a margin sampling value strategy. We then evaluate the proposed approach using the acoustic scene classification data set of 2017 IEEE AASP Challenge on Detection and Classification of Acoustic Scenes and Events(DCASE). On the evaluation set, an accuracy of 64.0 % from bidirectional gated recurrent neural networks is obtained when fusing the spectrogram and the bump scalogram, which is an improvement on the 61.0 % baseline result provided by the DCASE 2017 organisers. This result shows that extracted bump scalograms are capable of improving the classification accuracy,when fusing with a spectrogram-based system.

A Study on the Symbolism in The Garden Party

引用

海外英语 2015年第20期 165-167,173页

作者：王伊阳 Foreign language college Zhongyuan University of Technology

The object of this research focuses on exploring the writing techniques of Katherine Mansfield's short stories. The paper uses illustration and contrast analysis to discuss symbolism in Mansfield's masterpiece The Garden Party. The main contention includes: The symbolic meaning of the"garden party"itself, the symbols of the two worlds(the world of"garden party"and the world of"lane"), the image of the main characters, the representative objects and the implied meaning of the ending. It can be concluded that the"life and death"is the story's theme which has a profound significance of reality through the young girl Laura's process of maturing.

Study on the Applied Talents Training in Local colleges

引用

International Journal of Technology Management 2015年第7期 55-57页

作者： Wang Qiuyuan college of Foreign language Baicheng Normal University

It is the inevitable requirement to emphasize applied talents training in modem society when the economy and society are under rapid development, during which the local colleges are obliged to undertake this significant responsibility. Taking the training of applied talents as the core during the teaching and education is the important step taken by local colleges in Jilin to adapt to the social demands. The quality of the talents would directly influence the contributions made to the society by local colleges and its own sustainable development. Nowadays, the local colleges in Jilin should reinforce their efforts in the training of applied talents and deepen the reform comprehensively from the educational concepts, training programs and teaching courses so as to effectively realize the teaching objectives of the training on applied talents.

Consciousness of Sorrow and Worry and the National Pedagogy of Reform

引用

文化研究 2013年第1期 238-282页

作者： Yipeng Shen language and Culture Studies and International Studies Trinity College

River Elegy(Heshang)is a Chinese TV documentary aired on Chinese Central Television(CCTV)in *** provocative condemnation of the thousand-year-old'yellow civilization'(huangse wenming黄色文明)of China stirred up a tornado of controversies among Chinese *** debates and reflections on the documentary both inside and outside China have made Heshang one of the most intriguing'phenomena'in contemporary Chinese *** paper proposes a new perspective to read Heshang,tackling it as a historically situated narrative that embodies a post-Mao intellectual discourse of the national *** the new context of post-Mao China,what does Heshang tell of the relative positionalities of the intellectuals,the masses,and the state in the frame of Chinese modernity?How do we dialectically understand the documentary’s national pedagogy of reform in relation to the elusive agency of the low-quality Chinese masses?With these questions in mind,I revisit Heshang’s claim of weak political agency as an embodiment of low people quality.I argue that the national sentiment of the consciousness of sorrow and worry(忧患意识)simultaneously suggests and subverts the national pedagogy of reform promoted by the Heshang intellectuals.
