Web27 de jun. de 2024 · Momentum also helps in smoothing out the variations, if the gradient keeps changing direction. A right value of momentum can be either learned by hit and trial or through cross-validation. Momentum uses past gradients for updating values, as shown in the formula below. The value v associated with momentum is often called the ‘velocity’.
