Rate of convergence of some multivariate neural network operators to the unit

This paper deals with the determination of the rate of convergence to the unit of some multivariate neural network operators, namely, the Cardaliaguet–Euvrard and ‘squashing’ operators. This is given through the multidimensional modulus of continuity of the involved multivariate function or its partial derivatives of specific order that appear in the right-hand side of the associated multivariate Jackson type inequality.
