From: Using a kernel density estimation based classifier to predict species-specific microRNA precursors
The decision boundary plots, where (a) and (c) are generated by SVM and (b) and (d) are generated by RVKDE. The x-axis is frequency of the dinucleotide "UU", and the y-axis is base pairing propensity[44]. The black circle is a testing pre-miRNA for the pre-miRNA Caenorhabditis elegans miR-260. The red and blue circles represent positive and negative training samples. In (c) and (d), training samples not involved in the decision function of the classifiers are removed.
