Pairwise protein structure comparison has taken significant scientific research effort in last two decades. Even though it all started with alignment-based comparison methods, recently there are several non-alignment based methods that have shown good potential. One such approach is based on shape descriptors. These methods use histograms or vectors to represent the molecular shapes. They have shown...
Dihedral angles play a very important role in determining the backbone structure of any protein macromolecule. The backbone structure is associated with protein function. In this work, dihedral angles along with geometric angles have been used as features to represent protein structures. These features are then used to perform protein secondary structural classification.
Big Data presents challenges for predictive analytic algorithms due to the possibility of non-stationary populations. Concept drift detection algorithms can be used to detect changes in underlying distribution in order to retrain. Most concept drift detection methods are known to scale to a relatively low number of features (a few hundred). However, in many areas, datasets with thousands or even tens...
