June 2011 High School graduation, undergraduate course, 2013 summer vacation August, the school for one months of mathematical modeling training, and then the second weekend in September in southeast University to participate in a three-day National Mathematical Modeling contest, "accident" won the National Mathematical Modeling Competition , June 2015 undergraduate, graduate, 2016 summer vacation, because the internship did not participate in the school organization of Mathematical Modeling training, September, the third weekend in Nanjing University of Posts and telecommunications in the 4.5-day National Postgraduate Mathematical Modeling Contest, "wish" to obtain the National Graduate Mathematics Modeling Competition First Prize, Subsequently participated in the "Huawei Cup" 13th Graduate Mathematical Modeling Competition Award Conference at Chongqing University, and won the award as the first prize representative. One is the second prize of "accident", one is "wish" first prize, embodies the charm of mathematical modeling, and his little maturity, plus on his body with a trace of luck. Mathematical modeling "Love You Not Easy". Too many halo enveloped the mathematical modelling contest, Shanghai settled in Add points, the world's largest scale, the Ministry of Education and Graduate Education Development Center, Tsinghua University, Southeast University, higher education, Huawei and other organizers, organizers, organizers, sponsors, each took out is the industry famous famous. Fortunately, in the sophomore ignorant to participate in the training of mathematical modeling, hot summer vacation, others at home cool and cool, their own in the school to look at the heavenly book topics, but also to answer, learning matlab, spass and even the simplest of Excel and so on, so that the training after school out of the training building, I heartily shouted a sentence " After the math modeling, the remaining undergraduate two years I no longer want to step into the physical laboratory building (training site) Half steps ", holding a trial mentality, participate in mathematical modeling contest, three days, two days a day from the Pukou 6 o'clock daily from the school bus to Kowloon Lake, and then 9 more from the Kowloon Lake ride back to Pukou, 6 hours of sleep time, Last day straight all night. Handed the mathematical modeling of the paper, feeling is a face, do not know what to write, not a little grasp the award, or even the provincial prize is not hope, but I feel that our group is still our school to do better, although we changed to the last time, but still feel is not hope, but happiness is so sudden, We are the only one in our school to obtain the second prize of the National Mathematical Modeling competition, there is a team is the third prize in Jiangsu Province, my good friend that team. Graduate stage, although in the South Post just read a year, but feel that they have improved a lot, do things to start the right to be sure, but the guilty is not to participate in the school organization of Mathematical Modeling training, September the third weekend I from the company to go back to school to attend, after 4 days and 4 nights of effort, submitted papers, The national second prize of their own more certainty, did not expect the final is the national first prize, and in this topic ranked in 13 or so, because they usually have a certain understanding of data mining algorithms, this topic can be combined with data mining algorithms and statistical analysis method。 Mathematical modeling, "Love You Not Easy", "love you do not regret." On December 11, 2016, on behalf of the first prize-winning team, I attended the award ceremony held by Chongqing University and attended the top 10 papers sharing seminar in the afternoon. Let me further realize Daniel's answer thinking, model of the ingenious, the professional solution. What impresses me most is that a team of the Ncepu Power Systems Institute, because of the lack of professional knowledge of SNP loci, genetics, traits, and so on, is purely from a mathematical point of view, perfect to play their statistical advantage, modeling and building the gorgeous let everyone in the presence praise There is also a team from ECNU life Information Science Professional team, the team belongs to the professional, they from their professional perspective, the use of professional tools, from a professional perspective, pointing out the shortcomings of other teams, such as a series of scientific, Nature the above paper to prove the rationality of his thesis. 5 days less than the time, they make the paper and the experiment is perfect, heartily admire. Participate in the exchange also has an experience is, different school gap is not small, although our ranking is very front (the exchange of the top 10, we are three places, we can be excellent in the excellent experience exchange), but we have to admire 985 of school knowledge of the professional and rapid learning ability. From the Wikipedia, science, nature, and so on professional, scientific and technical areas of the ability to search information and the ability to reproduce the experiment, I still have a long way to go. Combined with their own experience, talk about participating in mathematical modeling experiences: (1) Make full use of Wikipedia, the individual think that the award is not a problem, but the first prize is more difficult, (2) from the point of view of mathematics, with mathematical methods to solve problems, especially computer professional, Do not always think of machine learning algorithms, the use of chi-square test, Logistic regression analysis method, the use of decision trees, random forests and other mathematics teachers do not know the advantages of the method is not the dominant, because the teacher of the review paper is generally a math teacher. (3) Do the topic to do the whole, for example, you use Chi-square test, you must give confidence, give the test, this year if there is no test, basically and win-bye, first prize more impossible. (4) Do the topic can choose several methods to carry out their own solution verification. For a specific result of the topic, the results of their own solution is very important, this year, the teacher of the question B is clear that the accuracy of the answer is less than 60% of the reference answer, the basic can not be the first prize. (5) Do the topic must join the national mathematical modeling of the discussion group, many people share the answer, it is possible to join some of Shanghai University's specific topic discussion group, inside the teacher will share the idea of doing the problem. (6) Mathematical modeling is the comprehensive ability of the exercise, the study is fast learning ability, do not hold out the topic is your professional lucky heart, I am doing safe, estimated that in the holding of ten years will not be safe, password type of the topic, get the topic carefully analyzed,Mentality is very important, seriously finished, the results out, to find a mathematical model, writing a beautiful paper is the king. (7) must teamwork, do a good job of division, a person again cow, do not make all things, personal feeling first prize must three people work together. As far as we are concerned, we are alone in a mathematical model, a person's main code implementation, a person to write a thesis, the division of labor to be clear. Finally, thanks to the organization of the Organizing Committee of Mathematical modeling, let oneself participate in the game of their lifetime unforgettable, thanks to the support of the school, thanks to the cooperation of the teammates, they are not able to complete the mathematical modeling problem for a short time; Thanks to all the people involved in mathematical modeling!
