报告摘要：

I will initially touch on some basic ideas in Artificial Intelligence, Brain-Computer Interface and Big Data, and their applications. I will argue that artificial intelligence is understood when computers emulate cognitive functions associated with human mind, while brain-computer interface is a technology that allows a human to control peripheral devices with thought. Big data, on one hand, refers to data sets that are so voluminous that require hardware with larger capacity and more capable data processing software. But on the other hand, often big data does not mean a lot of data, especially in scientific and technological applications, as the volume of available data from experiments or observations are small. Big data, in this case, refers to the ability to understand, analyse, make predictions and even to control the system, based on software methods and techniques to handle small data sets. One such powerful method developed by us recently – see references below – is compressive sensing. It enables us to deal with the reverse engineering, systems identification, or inverse problem in complex nonlinear dynamical systems and complex networks. Our ideas based on compressive sensing, in combination with innovative approaches, generates a new paradigm that offers the possibility to address the fundamental inverse problem in complex nonlinear dynamics and networks. In particular, in this talk, I will argue that evolutionary games model, a common type of interactions in a variety of complex, networked, natural systems and social systems, allows us to reconstruct the social network from small amounts of data.
