w88 casino News Network (provided by the Graduate Affairs Department)The 17th "Huawei Cup" China Graduate Student Mathematical Modeling Competition was held from September 17 to 21, 2020. The competition results were announced recently. Our graduate students have achieved impressive results in the competition. A total of 20 teams from w88 casino participated in this competition, among which the "Brick Moving Team WLW" team won the first prize, and the "Comparative Advantage" team and the "We Do It All Team" won the third prize.
The "WLW" team is composed of three students from the Quantitative Department of the w88 casino of Finance, Wang Dejiang, Li Weisheng, and Wang Tong. The competition topic is p3000 waveform identification and sleep band prediction. It predicts sleep waves through the study and analysis of the brain's EEG signals. By using programming software such as python and matlab, machine learning and other related knowledge, combined with clustering methods, and using convolutional neural networks and xgb algorithms, the three students successfully identified five characters to be recognized and completed the sleep band prediction. The accuracy of the model verification set reached 92%. Finally, based on the above work, they jointly completed the paper "Research on the EEG Signal Analysis and Discrimination Model".
The "How Do We Do All Team" team is composed of Zou Huiyuan from the Global Value Chain Research Institute, Zhou Ling from the Insurance w88 casino, and Nie Li from the w88 casino of International Economics and w88. The title of the paper is "Research on Optimization of Aircraft Center of Mass Balance Fuel Supply Strategy." Mainly by establishing differential equations to solve the coordinates of the center of mass of the aircraft at different pitch angles; and then using goal programming and genetic algorithms to solve for the optimal fuel supply speed of the aircraft under different constraints, thereby formulating the best fuel supply strategy.
The "Comparative Advantage" team is composed of three students, including Yu Yufang from the w88 casino of Government and Xie Jie from the w88 casino of International Economics and w88. In view of the fact that the visibility detection of video images is becoming another major development trend in the field of visibility detection, the team chose question E and tried to make a certain marginal contribution to this. Through full online cooperation, we established a measurement model that can explain the specific relationship between visibility and surface meteorological observation characteristics, a deep neural network model based on Tensorflow that can predict visibility, and a mathematical model that can predict the changing trend of heavy fog. We also jointly completed a digital-model paper titled "Visibility Estimation and Prediction Based on the Evolution of Heavy Fog."
The Chinese Graduate Mathematical Modeling Competition is guided by the Degree and Graduate Education Development Center of the Ministry of Education and hosted by the Youth Science and Technology Center of the China Association for Science and Technology. It is one of the themed events of the "China Graduate Student Innovation and Practice Series Competition". The competition is open to postgraduate students to conduct applied research on mathematical modeling. It is a large platform for postgraduate students to improve their ability to build mathematical models and use Internet information technology to solve practical problems, and to cultivate the spirit of scientific research innovation and teamwork awareness. The Graduate Affairs Department of the w88 casino Party Committee carefully carried out the organization and mobilization, team training, expert guidance and other work for the competition.
