Feature selection for protein dihedral angle prediction
2017 9th International Conference on Computational Intelligence and Communication Networks (CICN), 2017 Three-dimensional structure prediction has crucial importance for bioinformatics and theoretical chemistry. One of the main steps of three-dimensional structure prediction is dihedral (torsion) angle prediction. As new feature extraction methods are developed the dimension of the input space increases considerably yielding longer model training and ...
