Uniform weighted approximation by positive linear operators

We characterize the functions defined on a weighted space, which are uniformly approximated by a sequence of positive linear operators and we obtain the range of the weights which can be used for uniform approximation. We, also, obtain an estimation of the remainder in terms of the usual modulus of continuity. We give particular results for the Szász-Mirakjan and Baskakov operators. Mathematics...

Continuously Differentiable Exponential Linear Units

Exponential Linear Units (ELUs) are a useful rectifier for constructing deep learning architectures, as they may speed up and otherwise improve learning by virtue of not have vanishing gradients and by having mean activations near zero [1]. However, the ELU activation as parametrized in [1] is not continuously differentiable with respect to its input when the shape parameter α is not equal to 1...

Statistical Fuzzy Approximation to Fuzzy Differentiable Functions by Fuzzy Linear Operators

In this paper, we obtain fuzzy approximations to fuzzy differentiable functions by means of fuzzy linear operators whose positivity condition and classical limits fail. In order to get more powerful results than the classical approach we investigate the effects of matrix summability methods on the fuzzy approximation. So, we mainly use the notion of A-statistical convergence from summability th...

On the order of weighted approximation by positive linear operators

An estimation of approximation of continuous functions by positive linear operators in weighted norm using the weighted modulus of continuity is established. Application of the main result to the known Gadjiyev∗ -Ibragimov operators is given.

On the Approximation of Trivariate Functions by Means of Some Tensor-product Positive Linear Operators

In this paper we introduce and study a trivariate linear positive operator, depending on some parameters, denoted by L〈α,β,γ〉 m,n,r , useful for the approximation of functions of three real variables continuous on the unit cub C3. The corresponding approximation formula has the degree of exactness (1, 1, 1). For the remainder of this formula we give several representations by using the second-o...
