Sentence examples for estimate the gradient from inspiring English sources

An Artificial Neural Network is employed as a Critic to estimate the gradient of cost-to-go function.

We assume that the agents can estimate the gradient of the cost function element-wise by measuring the steady state response of the system.

The agents know their position and the local value of the field, and by communicating with their neighbors estimate the gradient direction of the field.

The proposed algorithm requires less number of experiments to estimate the gradient and can be used with the iterative learning control proposed previously.

Provided that the energy functional is differentiable with respect to its input parameters, it is possible to estimate the gradient with respect to each parameter using a numerical method known as the central difference approximation, thereby avoiding mathematically complex differentiation.
