Webweight_decay – weight decay (L2 regularization coefficient, times two) (default: 0.0) weight_decay_type – method of applying the weight decay: "grad" for accumulation in the gradient (same as torch.optim.SGD ) or "direct" for direct application to the parameters (default: "grad" ) Webclass torch.optim.SGD(params, lr=, momentum=0, dampening=0, weight_decay=0, nesterov=False) [source] Implements stochastic gradient descent (optionally with momentum). Nesterov momentum is based on the formula from On the importance of initialization and momentum in deep learning. Example east loraborough
