Prof. Liu giving a lecture

Prof. Liu is the Associate Dean of the Department of Statistics and Data Science at Nankai University. He has been engaged in experimental design and data analysis for a long time.

Prof. Liu pointed out: When doing experimental design, it’s better to bypass complicated models to obtain pseudo-models.

Prof. Liu introducing OSOA

He then gave an elaborated introduction to his newly designed model: column-orthogonal strong orthogonal arrays (OSOA), and how it is constructed.

The construction of OSOA

Prof. Liu demonstrated the application of OSOA and its comparison with some other existing methods. He drew the following conclusions: In one dimension, this model has a greater level number. In two dimensions, the space filling of the model is higher.

Q&A session

At the end of the lecture, Prof. Liu interacted with the audience and answered their questions. During the Q&A session, he explained more about the advantages of OSOA.
