By using the underlying theory of proper scoring rules, we design a family noise-contrastive estimation (NCE) methods that are tractable for latent variable models. Both terms in NCE loss, one data samples and noise samples, can be lower-bounded as variational Bayes, therefore call this losses fully estimation. Variational autoencoders particular example also understood separating real from syn...

in this paper, we investigate the existence of a positive solution of fully fuzzy linear equation systems. this paper mainly to discuss a new decomposition of a nonsingular fuzzy matrix, the symmetric times triangular (st) decomposition. by this decomposition, every nonsingular fuzzy matrix can be represented as a product of a fuzzy symmetric matrix s and a fuzzy triangular matrix t.

there are two interesting methods, in the literature, for solving fuzzy linear programming problems in which the elements of coefficient matrix of the constraints are represented by real numbers and rest of the parameters are represented by symmetric trapezoidal fuzzy numbers. the first method, named as fuzzy primal simplex method, assumes an initial primal basic feasible solution is at hand. t...

One of the group's main activities involves distributed data mining. The GOLF framework developed earlier was extended with the capability to adapt to dynamically changing environments and concept drift. The basic idea behind this method is to maintain a fixed age distribution in the network among the models. Young models help in adapting to sudden changes, while older models represent stabilit...

A fully ionized plasma is assumed. T o this plasma cylindrically-symmetric magnetic fields are applied, thus causing a pinch collapse. The plasma is treated in hydromagnetic approximation, including electric and thermal conductivity. Separate temperatures are assigned to the electrons and ions. Two schemes are developed for solving numerically the resulting system of six partial differential eq...

Any primitive binary word contains at least two unbordered conjugates. We characterize binary words that have exactly two unbordered conjugates and show that they can be expressed as a product of two palindromes. In this paper we relate two elementary properties of finite words: being a palin-drome and being unbordered. These two concepts are in a sense complementary. Unbordered words have maxi...
