A Novel Feature Selection Method Using Backpropagation for Propositional Formula Matching – Propositional formula matching (PFFM) aims to extract a specific formula from the input data. For this purpose, we use one-to-one correspondence between a formula and the input set to learn the relationship between the formulas and the values of a metric function in the matrix space. In particular, we propose a method that learns the relationship between a formula and every value of a metric function in different matrices. We define a matrix factorization-based model which learns the matrix metric function for each set of formulas to provide a measure of similarity between the formulas and the values of metric functions. We also propose a novel feature selection method for PFFM, which we call Recurrent Matrix Factorization (RBMF) feature selection. Our method performs well on benchmark databases as well as benchmark data. Empirical results demonstrate that our approach significantly outperforms other existing feature selection methods on PFFM and other well-known database datasets, including the FITC database (1,2,3).

We propose a method of estimating the objective function using the covariance matrix of the coefficients. The covariance matrix has many special characteristics such as the coefficient’s normality, its independence, and the coefficients’ relationship to the variable. We present a method of exploiting and refining the covariance matrix in the form of a sparse coding scheme. In particular, we derive a generalization assumption to obtain a simple algorithm to learn the covariance matrix, known as the covariance coding scheme. In this scheme, the covariance matrix is represented by a latent function whose latent variable is assumed to be a covariance matrix. The latent variable is assumed to be of a Gaussian process. The covariance matrix is then learned by a supervised learning algorithm. We provide an efficient algorithm based on a Bayesian Bayesian approach to learning the covariance matrix. The framework makes use of a model of the covariance matrix to approximate the covariance matrix. To verify our method, we present extensive experiments on synthetic and real data.
