On the morning of September 6, our college held an academic exchange meeting for young teachers in the lecture hall on the first floor of the college building.This academic exchange was presented by 8 teachers from different research directions in the School of Computer Science, they exchanged and discussed about their respective research contents.The meeting was presided over by Yu Zhiwen, the secretary of the CPC Committee of School of Computer Science. Some professors, young teachers, and graduate students of the College participated in this meeting.
First of all, Secretary Yu welcomed the teachers and students, and introduced the purpose and significance of the academic exchange meeting. It is hoped that teachers can share the research contents, methods and achievements to enlighten each other and broaden their research visions. At the same time, it is indicated that the academic exchange meeting will be a normal activity of the college, constantly innovate the contents and forms, and promote the deepening of teachers' scientific research exchange and the improvement of their scientific research level.
Zhang Kailong, Wang Zhu, Yao Yuan and Wang Jihe from the first department, Song Lingyun and Chen Bolin from the second department, and Cao Congqi and Liang Guoqiang from the third department gave reports in turn.
Mr. Zhang Kailong made a report on the topic of "Boating on the Sea of 'Learning' -- Qi, Dao and Shu in Scientific Research", and discussed the dialectical relationship between the connotation and dialectic of "Qi", "Dao" and "Shu" in scientific research by combining the research mission and connotation of research universities and his understanding of scientific research work, and how to keep gathering "Qi" and nurturing "Qi" , choosing "Dao" to cultivate "Dao" and combining "Shu" with "Shu" in scientific research activities with the attitude of self-education, and improve academic quality and research ability.
Professor Wang Zhu's report was titled "Intelligent Wireless Sensing Research Practice". The report combined the perception of human behavior to understand this scientific question, based on the theoretical model of wireless perception, the paper tried to introduce the research practice of intelligent wireless perception from the perspectives of whether there are people in the target perception area (dynamic detection), who are there (identification) and what are they doing.
Teacher Yao Yuan made a report on "Sybil Attack Detection in Vehicle-borne Wireless Autonomous Network". Aiming at the malicious attack of Sybil Attack in vehicle-borne network, a pure distributed detection method independent of channel model was proposed.By detecting the similarity of RSSI time series instead of direct ranging location,at the same time, aiming at the problem that the malicious node changed RSSI sequence by controlling sending power, a method based on multi-mutation detection was proposed to estimate.The design method has been verified by simulation and real vehicle environment, and achieved good results.
The title of Mr. Wang Jihe's report was "Green Artificial Intelligence System". By analyzing the source of the energy efficiency problem in artificial intelligence system, the paper focused on solving the energy efficiency problems of key system bottlenecks such as system-level storage and multiplication-accumulation calculation, and proposed a linear and smooth model scale control theory for the popular embedded neural network architecture, so as to realized the flexible deployment of artificial intelligence under the condition of limited resources.
As a new teacher, Song Lingyun shared the report themed "research on image recognition algorithm based on cross modal semantic correlation", in the case of the present explosive growth in image data and the majority of the image data without annotation, introduced how to develop efficient and accurate algorithm of image content understanding, which included three tasks: image classification, object detection and image text description automatic generation.In addition, the paper introduced the research problems faced by each task, mainstream solutions, and the latest research results.
Teacher Chen Bolin's report was simple in its depth, "several research hotspots on disease gene identification" were discussed. This paper mainly introduced the hot issues of disease-related gene recognition in recent years, which included from the initial related genes of similar diseases to the recognition of a single disease-related gene, also included the recognition of abnormal genes for the onset stage of cancer to the two-way fine classification of cancer subtypes and cancer stages.The research and analysis of these algorithms had important guiding significance for people to understand the pathogenesis and carcinogenesis of cancer.
Teacher Cao Congqi's report was entitled "Research on Human Behavior Recognition Based on Temporal and Spatial Models". Aiming at the problem that it is difficult to effectively model the temporal and spatial information in video data and accurately identify the behavior, based on skeleton data, color video data, and the combination of skeleton information and color video, this paper introduced the proposed behavior recognition method, and proposed a learning algorithm which can automatically remove the camera global motion for the first perspective interactive gesture recognition application.
Professor Liang Guoqiang presented a report entitled "Human Posture Estimation and Its Application in Cross-Perspective Identity Recognition".Firstly, a two-dimensional human pose estimation method based on the limb graph model was proposed, and a structure relation model was used to model the relationship between human limbs and nodes, and good estimation accuracy was obtained.Secondly, starting from the inconsistency of the estimation accuracy of the position of human body nodes, a cross-angle identification based on the confidence of human body attitude estimation was proposed, which verified inaccurate gesture can still be used for identification.
Finally, Shang Xuequn, deputy dean of the college, summarized the research and expressed his gratitude to the teachers who participated in the report. At the same time, he pointed out that the academic exchange meeting of the college can not only let teachers know the cutting-edge issues in related fields, but also exchange and share the research results, which is of great long-term significance to enlighten scientific research ideas and promote interdisciplinary.
