An algorithm for classification over uncertain data based on extreme learning machine

In recent years, along with the generation of uncertain data, more and more attention is paid to the mining of uncertain data. In this paper, we study the problem of classifying uncertain data using Extreme Learning Machine (ELM). We first propose the UU-ELM algorithm for classification of uncertain data which is uniformly distributed. Furthermore, the NU-ELM algorithm is proposed for classifying uncertain data which are non-uniformly distributed. By calculating bounds of the probability, the efficiency of the algorithm can be improved. Finally, the performances of our methods are verified through a large number of simulated experiments. The experimental results show that our methods are effective ways to solve the problem of uncertain data classification, reduce the execution time and improve the efficiency. (C) 2015 Elsevier B.V.
