Optimizer weight_decay
WebJun 3, 2024 · to the version with weight decay x (t) = (1-w) x (t-1) — α ∇ f [x (t-1)] you will notice the additional term -w x (t-1) that exponentially decays the weights x and thus forces the network to learn smaller weights. Often, instead of performing weight decay, a regularized loss function is defined ( L2 regularization ): WebJul 2, 2024 · Weight Decay can hurt the performance of your neural network at some point. Let the prediction loss of your net is L and the weight decay loss R. Given a coefficient λ that establishes a tradeoff between the two. L + λ R. At the optimum of this loss, the gradients of both terms will have to sum up to zero: L = − λ R.
