Abstract—This paper proposes a noise filter with L₂-norm distance method to design a classification of RNA sequences for the species identification, including of the small sample size of the nucleic acid sequence. This method amends and expands the study of Hu et al. in 2011 [1]. We verify this method with the biological sample "slipper orchids" and its hybrid for biological species identification test. The result shows that we can distinguish the paternity of a hybrid among a set of samples of "slipper orchids" by using this method.
