Recently, the concept for determining the key parameters of agent-based models from empirical data instead of setting them artificially was sug- gested. We first review several agent-based models and the new approaches to determine the key model parameters from historical market data. Based on tile agents＇ behaviors with heterogeneous personal preferences and interactions, these models are successful in explaining the microscopic origi- nation of the temporal and spatial correlations of financial markets. We then present a novel paradigm combining big-data analysis with agent-based modeling. Specifically, from internet query and stock market data, we extract the information driving forces and develop an agent-based model to simulate the dynamic behaviors of complex financial systems.展开更多
