EnhancerPred: a predictor for discovering enhancers based on the combination and selection of multiple features

Abstract: Enhancers are cis elements that play an important role in regulating gene expression by enhancing it. Recent study of modifications revealed that enhancers are a large group of functional elements with many different subgroups, which have different biological activities and regulatory effects on target genes. As powerful auxiliary tools, several computational methods have been proposed to distinguish enhancers from other regulatory elements, but only one method has been considered to clustering them into subgr… Show more

“…iEnhancer-EL [70] and iEnhancer-2L [26] produced better outcomes using ensemble classifiers and achieved accuracy of 78.03% and 76.89% respectively in which they were successful in predicting strong enhancers with accuracy of 65.03% and 61.93% respectively. Whereas EnhancerPred [27] achieved 80.82% accuracy and used SVMs which produced slightly better results in predicting strong enhancers with 62.06% accuracy. Similarly, iEnhancer-2L-Hybrid [71]and iEnhancer-5Step [29] improved the accuracy results with their prediction model and acquired 77.86% and 82.3% accuracies respectively with identifying the strong enhancers with 65.83% and 68.1% accuracies respectively.…”

“…Furthermore, many other methods, such as EnhancerPred [27] and EnhancerPred_2.0 [28], were introduced to improve the performance by incorporating other features based on DNA sequences. iEnhancer-5Step [29] was recently developed using the hidden information of DNA sequences infused with Support Vector Machine (SVM) based predictions.…”

“…In order to distinguish the contribution of different features to the prediction model. To analyze these feature vectors, F-score method (Chen W. et al, 2016 ; Jia and He, 2016 ; Tang et al, 2016 , 2018 ; He and Jia, 2017 ) was adopted to rank the feature, in this study. The F-score value of the i -th feature is defined as: where , and are the average values of the i -th feature in whole, ncDNA and cDNA datasets, respectively.…”

“…It has been proven to be powerful in many fields of pattern recognition and data classification (Byun and Lee, 2002 ; Nasrabadi, 2007 ; Zhang N. et al, 2018 ;). More and more applications also proved that SVM also has strong data processing capabilities in the fields of bioinformatics (Xiong et al, 2011 ; Jia et al, 2013 , 2017 ; Cao et al, 2014 ; Liu et al, 2014 , 2017b ; Wei et al, 2015 ; Chen X. X. et al, 2016 ; Jia and He, 2016 ; Yang et al, 2016 ; Zou et al, 2016 ; Xiao et al, 2017 ; Qiao et al, 2018 ; Su et al, 2018 ). A set of ncDNA samples and cDNA samples were represented by the feature vectors.…”

“…Definitive epigenetic signatures of enhancer elements have been challenging to identify. A number of computational tools have been developed to predict enhancer elements from chromatin state and transcription factor in vivo DNA binding information (1)(2)(3)(4)(5)(6)(7)(8)(9)(10)(11)(12). Tools that attempt to measure predictive accuracy using only indirect evidence of enhancer activity, e.g.…”
