        ​​​​​​Abstract：

Interview

Q1: This paper on multi-sensor registration in 3D covers mathematical, computer and other expertise, which has many similarities with mathematical modeling. What are the similarities and differences between the actual research and the modeling competitions that you have participated in? How do you think about these similarities and differences? Do you have any suggestions for junior students?

A1: The most significant difference is the purpose. The purpose of mathematical modeling is for fun. The purpose of the actual research is to contribute. So while it seems that both are building models to portray problems and solve problems with algorithms, the actual research is much more serious. There are many concrete manifestations: for example, research needs to be compared with many existing algorithm results, and a literature review is needed to ensure that your research really makes sense. The research cycle is long and requires enthusiasm and patience.

From my personal research experience, I feel that one should take the initiative to actively participate in research projects, actively learn the knowledge related to their own research fields, and actively consult the supervisor and other researchers in the laboratory. In fact, when you are humbly asking for advice from others, everyone will be happy to help you. Second, we must be patient. Those simple and beautiful formulas in textbooks and papers are all summed up by scholars after many failures. If you want to do research well and effortlessly, it is simply impossible. It doesn't matter if you fail, just don't give up, sum up the experience and move on.

Q2: What are the options for computer science and engineering students? How do they prepare? The information in this area of expertise is updated very quickly, so it is more focused on the ability of learners to absorb and respond to information. How do you excel in professional study?

A2: Actually, I don't think we should limit ourselves to the profession. There is no absolute connection between a person and his/her major in choosing a direction in the future. For undergraduate study, you can take more elective courses. You can listen to some other majors of interest to you. Computer majors can also take more math and statistics classes, as well as philosophy, history, psychology, economics, and more. You can go online to find open classes offered by universities at home and abroad so that you can see a lot of perspectives from the world. You will find that the roads you can choose will be very wide with many options. Even if they are not useful for a while, in my experience, you will find their role in a magical node in the future.

In fact, students of every major need to have such ability if they want to excel. I think the most important thing is to be curious. This motivation is the most important. Network resources, including speeches and open classes, should be fully utilized. Mind maps can be very useful, and I am still learning. It is recommended that you take notes, especially mind map notes, and organize the knowledge into a framework so that you can understand deeper when you study, and the efficiency will be high when reviewing.

My experience is to spend more time studying how to think of learning as a kind of happiness and a kind of enjoyment. In positive psychology, there is a concept called “flow”, referring to the immersive experience that we have when we learn. For example, the knowledge to be learned shall be challenging (it is boring if it is too simple), but not beyond your self-learning ability (or it will be suffocating). My advice is to create such an experience for yourself. I don't think "No pain, no gain" is always correct. Learning does take a lot of effort, but it doesn't mean it is painful. If you can think of learning as a happy thing, you don't even need any self-control to force yourself to learn. You will choose to study unconsciously rather than playing games because reading is much more interesting than the latter.
