Blossom by blossom the spring begins. On the morning of April 14, a long-awaited academic lecture was held online in full swing. Weinan E, a professor at Princeton University and an academician of the Chinese Academy of Sciences, was invited to deliver the 3rd “Distinguished Lecture in Natural Sciences” at INS. The lecture “A Mathematical Perspective of Machine Learning” has amazed teachers and students at home and abroad. Shi Jin, Director of the Institute of Natural Sciences, Congming Li, Dean of the School of Mathematical Sciences, and more than 900 teachers and students from the School of Mathematical Sciences, SJTU, School of Physics and Astronomy, SJTU, Zhiyuan College, SJTU, and other domestic and overseas universities gathered on the “cloud” to participate in the meeting.
Academician Weinan E believed that the foundation of data science is machine learning. He shared the concept of machine learning from the perspective of a mathematician. He pointed out that traditional approaches, such as approximation by piecewise polynomials, wavelets, or other linear combinations of fixed basis functions, suffer from the curse of dimensionality. He would present a framework that is suited for analyzing machine learning models and algorithms in high dimension, and present results that are free of the curse of dimensionality. Finally, Academician Weinan E had an in-depth discussion with teachers and students online, and called on more young scholars to pay close attention to high dimension problems.
Since March, due to the impact of the global pandemic, many academic conferences of INS have been held online. Up to now, INS has held 1 international academic conference, 10 online academic reports. The average number of participants per meeting is more than 200. The academic activities received unanimous praise from scholars, teachers and students at home and abroad.
Weinan E, mathematician, mainly engaged in the research of machine learning, computational mathematics, applied mathematics and their applications in the fields of mechanics, physics, chemistry and engineering. In 1999, he became a professor of the Department of Mathematics and Applied Mathematics and Computational Mathematics of Princeton University. In 2011, he was elected as academician of the Chinese Academy of Sciences. He was elected as fellow of the American Mathematical Society.
