"This is a difficult question to answer. Let me sum up the following points: (1) I love research, (2) I am diligent and studious, (3) I have profound thoughts, (4) I have rich imagination, (5) I have a solid foundation and (6) I am modest. I have met many world-class scientists, almost without exception. The following are a few short stories I have experienced, heard or seen as evidence. I want to encourage you. Ito Ito is one of the greatest mathematicians of our time. He extended the calculus method to stochastic process and established Ito calculus. This method is widely used in stochastic differential equations, financial mathematics and other fields. When I was an undergraduate at Kyoto University in Japan, Mr. Ito retired from Kyoto University. I went to listen to his' last lesson'. I remember the conclusion of Mr ITO's report vividly. He said, "I study math because it is interesting." As soon as the voice fell, the audience broke into prolonged applause. Persi Diaconis is a famous statistician. /kloc-started to be a magician at the age of 0/4. 18 I bought a probability book and found that I couldn't understand it at all, so I started studying mathematics at night school at the age of 24. Later, he received a doctorate in mathematics from Harvard University, became a professor at Stanford University, and became an academician of the American Academy of Sciences. One of Diogenes' famous research results is that he proved that playing cards can only be washed seven times, and he really turned from a magician to a mathematician. I have heard Diogenes' lecture on classified learning. What impressed me was that he was so devoted that he would close his eyes from time to time during his speech and completely enter his own world. Rakesh Agrawal put forward many important concepts and methods of data mining, such as association rule mining algorithm. He said: "When I choose a research topic, I must consider whether it will have an impact in ten years. "I once accompanied him to a restaurant in Beijing for dinner. As soon as he entered the door, he slowed down, poked his head out curiously like a child and leaned against the glass cabinet next to him. There used to be many dolls in national costumes. Laksh studied there for a long time and said "good" in English with an Indian accent, with a happy smile on his face. Like many scientists, Laksh is an energetic and curious person. Michael Jordan is one of the most influential scholars in the field of machine learning and a representative of Bayesian learning. Jordan has trained many excellent students, and much of the work he and his students have done is a milestone. Jordan didn't come from a prestigious school, but he became a professor at MIT and Berkeley with his intelligence and hard work, and was elected as an academician of the American Academy of Sciences on 20 1 1. Jordan has formed a habit for many years that he must read a paper before going to bed at night. Leo Breiman is an outstanding statistician who invented CART and Bagging algorithms. Brayman thinks that most of the current mathematics education is a failure. It is important for children to like math, because math is very interesting. He personally went to the fifth grade of primary school to teach mathematics. Brayman recalled that experience before his death: "We played all kinds of games together. They learned complex things such as analytic geometry and algebra in the game. "[1] Robert Schapire, who invented the famous machine learning algorithm, won the Golder Prize, the highest prize in computing theory, together with Yoav Freund. I once asked Rob, "How did you come up with AdaBoost?" His answer is simple: "Because we proved that we can upgrade a weak classifier to a strong classifier, we later thought of AdaBoost. "It seems that everything is reasonable. His expression was as calm as usual. First-class scientists have reached a very high level of thinking, and many inventions and discoveries are produced by natural reasoning, not by epiphany. Some people say that edward witten is the greatest theoretical physicist of all time, while others say that he is Einstein today. Witten established and developed many physical theories, especially superstring theory. He has written more than 200 papers and cited the H index to rank first in physics. He won many awards, including the Fields Medal in mathematics. Witten has a quick mind and often comes up with many ideas. Because of this, he never stints on his own ideas, and only puts the best ideas into research. He said: "When I was young, I woke up every morning with a feeling that today I would have a better idea than ever before." [2] Peter bartlett founded the analysis method of learning generalization ability, and he is the leader of machine learning theory. Peter's machine learning lecture notes are clear in thinking, rigorous in proof and concise in narration, which makes people feel that it is a pleasure to read. Once, Peter's son's school asked him to give a class to elementary school students, and the content was calculus! He said that he spent a lot of time preparing lessons, but it also showed that he had a deep theoretical foundation. Ross Quinlan won the highest honor award in the field of data mining, KDD Innovation Award 20 1 1. I heard Mr. Quinlan's report more than ten years ago. At the end, an audience boldly asked, "What is variance?" The Australian gentleman who looks like Lincoln didn't show impatience. Instead, he patiently explained, "I'm not a statistician.
