  • Model of Optimal Centroids Approach for Multivariate Data Classification

    • Authors: Lê, Thị Cẩm Bình; Pham, Van Nha (2021)

  • Particle swarm optimization (PSO) is a population-based stochastic optimization algorithm. PSO was inspired by the natural behavior of birds and fish in migration and foraging for food. PSO is considered as a multidisciplinary optimization model that can be applied in various optimization problems. PSO's ideas are simple and easy to understand but PSO is only applied in simple model problems. We think that in order to expand the applicability of PSO in complex problems, PSO should be described more explicitly in the form of a mathematical model. In this paper, we represent PSO in a mathematical model and apply in the multivariate data classification. First, PSOS general mathematical m...

  • Multi-view fuzzy co-clustering algorithm for high-dimensional data classification

    • Authors: Lê, Thị Cẩm Bình; Pham, Van Nha (2020)

  • Multi-view clustering considers the diversity of different views and fuses these views to produce a more accurate and robust partition than single-view clustering. In this paper, we proposes a multi-view fuzzy co-clustering algorithm for high-dimensional data classification. We call MvFCoC algorithm. The proposed algorithm is demonstrated through experiments on benchmark data sets. The experimental results show that the clustering quality is better by evaluating using validity indexes in comparison with previous methods.
