Defines a class in python with a (not optimized) version of gradient descent, in addition to line search which improves the method's convergence capabilities. Using the class Gradient_Descent ...

Abstract: This paper addresses the robust gradient learning (RGL) problem. Gradient learning models aim at learning the gradient vector of some target functions in supervised learning problems, which ...

Abstract: This paper analyzes the relationship between the residual frame and the previous frame in motion-compensated video coding. It is found that the variance of the residual signal depends on the ...
