WebNov 9, 2024 · 1 Answer Sorted by: 2 The two constraints you have are: lr (step=0)=0.1 and lr (step=10)=0. So naturally, lr (step) = -0.1*step/10 + 0.1 = 0.1* (1 - step/10). This is known as the polynomial learning rate scheduler. Its general form is: def polynomial (base_lr, iter, max_iter, power): return base_lr * ( (1 - float (iter) / max_iter) ** power) WebApr 7, 2016 · 4 Answers Sorted by: 216 The learning rate is a parameter that determines how much an updating step influences the current value of the weights. While weight decay is an additional term in the weight update rule that causes the weights to exponentially decay to zero, if no other update is scheduled. WebOct 31, 2024 · These methods are same for vanilla SGD, but as soon as we add momentum, or use a more sophisticated optimizer like Adam, L2 regularization (first equation) and weight decay (second equation) become different. AdamW follows the second equation for weight decay. In Adam weight_decay (float, optional) – weight decay (L2 penalty) … burton lysecki books winnipeg
