MicroRNAs (miRNAs) are short.(~22nt. non-coding RNAs t.at.play an indispensable role in gene regulat.on of many biological processes. Most.of current.comput.t.onal, comparat.ve, and non-comparat.ve met.ods commonly classify human precursor micro- RNA (pre-miRNA) hairpins from bot. genome pseudo hairpins and ot.er non-coding RNAs (ncRNAs). Alt.ough t.ere were a few approaches achieving promising result. in applying class imbalance learning met.ods, t.is issue has st.ll not.solved complet.ly and successfully yet.by t.e exist.ng met.ods because of imbalanced class dist.ibut.on in t.e dat.set.. For example, SMOt. is a famous and general over-sampling met.od addressing t.is problem, however in some cases it.cannot.improve or somet.mes reduces classificat.on performance. t.erefore, we developed a novel over-sampling met.od named incre-ment.l- SMOt. t. dist.nguish human pre-miRNA hairpins from bot. genome pseudo hairpins and ot.er ncRNAs. Experiment.l result. on pre-miRNA dat.set. from Bat.wit. et.al. showed t.at.our met.od achieved bet.er Sensit.vit. and G-mean t.an t.e cont.ol (no over- sampling), SMOt., and several successsors of modified SMOt. including safe-level-SMOt. and border-line-SMOt.. In addit.on, we also applied t.e novel met.od t. five imbalanced benchmark dat.set. from UCI Machine Learning Reposit.ry and achieved improvement. in Sensit.vit. and G-mean. t.ese result. suggest.t.at.our met.od out.erforms SMOt. and several successors of it.in various biomedical classificat.on problems including miRNA classificat.on.

Det.iled knowledge of int.rfacial region bet.een int.ract.ng prot.ins is not.only helpful in annot.t.ng funct.on for prot.ins, but.also very import.nt.for st.uct.re-based drug design and disease t.eat.ent.

Moreover, t.e met.od promises an improvement.in t.e source of t.mplat.-based prot.in docking.

β-t.rn is one of t.e most.import.nt.reverse t.rns because of it. role in prot.in folding. Many comput.t.onal met.ods have been st.died for predict.ng β-t.rns and β-t.rn t.pes.
