WebLinear momentum is the product of a system’s mass and its velocity. In equation form, linear momentum p is. p = m v. You can see from the equation that momentum is … WebAdam and rmsprop with momentum are both methods (used by a gradient descent algorithm) to determine the step. Let Δ x j ( t) be the j th component of the t th step. Then: In Adam: Δ x j ( t) = − learning_rate BCMA ( g j 2) ⋅ BCMA ( g j) while: learning_rate is a hyperparameter.
