Fig. 2From: Deep neural networks for human microRNA precursor detectionOne-hot encoding and vectorization of pre-miRNA sequence. The seq_struc is the combination of nucleotide/base and the corresponding secondary structure indicated with different symbols. The left bracket “(“means paired base at 5′-end. The right bracket”)” means paired base at 3′-end. The dot “.” means unpaired base. The encoded sequence is padded with zero vectors to the length of 180Back to article page
