讲座内容：
The ceaseless and infinite development of nature science is an endless and continuous process during which mankind observes and summarizes the nature behaviors, and then gains knowledge. From data to knowledge is a quantum jump, during which key factors are extracted and classified into input features and output responses, and relationships between input features and output responses are analyzed and, if possible, explicitly expressed in mathematic equations. Materials data, especially the materials data of mechanical behaviors such as creep, fatigue, fracture etc., are often small and high dimensional. Domain knowledge plays a crucial role in machine learning of small data. An example is given in the presentation to emphasize the role of domain knowledge in machine learning of small data. The example analyzes the data of size-dependent strength of concrete. On the other hand, statistical leaning of small data might be able to evaluate theoretical models developed from domain knowledge.
