Gene regulatory network (GRN) inference from gene expression data plays an important role in understanding the intricacies of the complex biological regulations for researchers. In this paper, a new hybrid supervised learning method (HSL) is proposed to infer gene regulatory network. In HSL, according to the data imbalance ratio, three different supervised learning methods: direct classification, K-Nearest Neighbor (KNN) method and complex-valued version of flexible neural tree (CVFNT) model are chosen to classify. A novel filtering method based on integration of mutual information (MI) and maximum information coefficient (MIC) is proposed to eliminate the redundant regulations inferred by HSL. Benchmark data from DREAM 5 are used to test the performance of our approach. The results show that our approach performs better than the popular unsupervised Learning methods and supervised Learning methods.
