On the morning of July 3, at the invitation of the School of Management, Professor Nelia, the Deputy Dean of the Faculty of Physics at the University of Havana, Cuba, and Professor Milton gave academic lectures on "Applications of Nonlinear Dynamics and Chaos in Complex Systems" and "Python Programming for Machine Learning" respectively in the Lecture Hall 214 of the School of Management at Chang'an Campus. This lecture was the 15th session of the 2024 Overseas Lecture Series at the School of Management, chaired by Associate Professor Wu Bei, with participation from faculty and graduate students of the school.

At the beginning of the meeting, Wu Bei provided a brief introduction to the personal and academic backgrounds of Nelia and Milton, and extended a warm welcome to their visit.

During the meeting, Professor Nelia delved into nonlinear dynamics and chaotic phenomena from the perspective of complex systems, focusing on analytical methods, specific examples, and geometric analysis techniques. She provided a detailed explanation of first-order differential equations and their bifurcation phenomena, phase plane analysis, limit cycles and their bifurcations, the Lorenz equations, chaos theory, iterative mappings, period-doubling phenomena, renormalization and fractal geometry, strange attractors, and synchronization phenomena.

Through systematic theoretical explanations and analysis of real-world case studies, she helped the audience understand and learn these theories, and apply them to practical nonlinear dynamics problems. This enhanced their understanding and analytical skills regarding the behavior of complex systems.

Milton provided a comprehensive understanding of the Python programming language and its applications in machine learning, including data processing with numpy, pandas, and polar bears, an introduction to machine learning, practical machine learning, handling big data with PySpark, and processing images and videos using OpenCV and CNN with PySpark. He then demonstrated how to manipulate and analyze data, create data structures, and use general frameworks, and introduced knowledge in supervised and unsupervised learning, classification, and regression.

After the lecture, faculty and students asked questions about topics that interested them, and Wu Bei made a concluding remark for the event. This lecture not only acquainted the faculty and students of the School of Management with the basic concepts and techniques of machine learning, the latest research directions and trends in image processing, but also inspired everyone's enthusiasm for scientific research. It contributed to fostering a research atmosphere at the School of Management and laid a solid foundation for the advancement of academic research there.
