From: miRFam: an effective automatic miRNA classification method based on n-grams and a multiclass SVM
Center vectors comparison among three miRNA families (let-7, mir-17 and mir-9) and the dataset S (snoRNAs). All horizontal axes are the n-grams arranged in the order from trigrams to bigrams and unigrams. (A) Family centers before weighting; (B) Family centers after weighting; (C) The variances of n-gram feature values among the four families before weighting; (D) The variances of n-gram feature values among the four families after weighting.
