Reproducibility of decisive miRNAs (a) and mRNAs (b) influencing on classification. 100 hypergraphs are generated by randomly selecting miRNAs and genes, while another 100 hypergraphs are generated by our learning method (10 experiments with 10-fold cross validation). Each hypergraph includes 200 hyperedges consisting of three miRNAs and five mRNAs. The x-axis denotes the rank of the appearance of miRNAs or mRNAs, and y-axis is the number of miRNA or mRNA appearances. Both axes are log-scaled.
