Improving MiRNA prediction accuracy by deep learning strategies

Published:09 September 2015Publication History

ABSTRACT

MiRNAs are small non-coding RNAs, but perform important function in regulating the translation of mRNAs into proteins. Experimental identification of miRNAs is still challenging due to the fact that the biogenesis of miRNAs is a complex process and is regulated by many factors that have not been completely characterized. Therefore, developing knowledge-based computational predictors provides an alternative strategy to discover novel miRNAs. While many computational predictors have been developed, a perpetual theme in this field is to improve the prediction performance continuously. Inspired by the success of deep leaning strategies in many other fields, we developed novel miRNA meta-predictors by integrating several deep learning techniques, including: preprocessing of input features based on principal component analysis and non-linear transformation, and meta-strategy. The newly designed meta-predictors improved the prediction accuracy of miRNAs consistently by ~10% from the middle of 80% to the middle of 90%.
