报告摘要： In information fusion, regarding the set of considered predictive attributes (in classification, called feature attributes) in a data base as the universal set, nonadditive set functions defined on its power set can effectively describe the interaction among the contribution rates from various predictive attributes towards the fusing target, which can be regarded as a specified objective attribute. Such type of interaction is totally different from the traditional statistical correlationship. Relevantly, the classical linear aggregation tool, weighted sum, which can be expressed as a linear integral defined on the universal set, should be generalized to be some nonlinear integral. The Choquet integral, the upper integral, and the lower integral are the common types of nonlinear integrals. Data mining is just an inverse problem of information fusion. Using nonlinear integrals, some classical models in data mining, such as the multiregression and the classification, can be generalized as well. Once the necessary data set is available, the values of unknown parameters in these nonlinear models can be optimally determined through some soft computing techniques, including genetic algorism and pseudo gradient search, approximately. Since the above-mentioned interaction can be elaborately captured, the introduced new nonlinear models are significant and powerful in practice. They may be widely applied in bioinformatics, medical statistics, economics, forecast, decision making et al. In face of various challenges from big data, these nonlinear models may have relevant generalizations, adjustments, improvements, and deformations.
