The "preferences" P acts as an important role in Affinity Propagation (AP) clustering algorithm and has great influence on the clustering performance. In the original AP method, the P is set at the beginning and kept fixed during the whole process. However, it is difficult to select a suitable P to obtain laudable clustering performance in practical applications. In this paper, we proposed a novel AP algorithm supervised by Silhouette Index where P is adjusted in the iterative process. After applied to 11 artificial and real datasets, the experiment results show that our method can get higher In-group Proportion values and Fowlkes-Mallows Index values, which is more superior and steady than the original AP method.

More about this publication?
  • Bionanoscience attempts to harness various functions of biological macromolecules and integrate them with engineering for technological applications. It is based on a bottom-up approach and encompasses structural biology, biomacromolecular engineering, material science, and engineering, extending the horizon of material science. The journal aims at publication of (i) Letters (ii) Reviews (3) Concepts (4) Rapid communications (5) Research papers (6) Book reviews (7) Conference announcements in the interface between chemistry, physics, biology, material science, and technology. The use of biological macromolecules as sensors, biomaterials, information storage devices, biomolecular arrays, molecular machines is significantly increasing. The traditional disciplines of chemistry, physics, and biology are overlapping and coalescing with nanoscale science and technology. Currently research in this area is scattered in different journals and this journal seeks to bring them under a single umbrella to ensure highest quality peer-reviewed research for rapid dissemination in areas that are in the forefront of science and technology which is witnessing phenomenal and accelerated growth.
