This article proposes a penalized composite likelihood method for model selection in colored graphical Gaussian models. The provides sparse and symmetry-constrained estimator of the precision matrix thus conducts estimation simultaneously. In particular, uses penalty terms to constrain elements matrix, which enables us transform problem into constrained optimization problem. Further, computer e...

Reconstructability Analysis (RA) and Bayesian Networks (BN) are both probabilistic graphical modeling methodologies used in machine learning artificial intelligence. There RA models that statistically equivalent to BN there also unique BN. The primary goal of this paper is unify these two via a lattice structures offers an expanded set represent complex systems more accurately or simply. concep...

This study presents a robust and rigorous method based on intelligent models, namely radial basis function networks optimized by particle swarm optimization (PSO-RBF), multilayer perceptron neural networks (MLP-NNs), and adaptive neuro-fuzzy inference system optimized by particle swarm optimization methods (PSO-ANFIS), for predicting the equilibrium and kinetics of the adsorption of sulfur and ...
