Linear weight decay cosine lr
NettetSummary. Weight decay is a regularization method to make models generalize better by learning smoother functions. In the classical (under-parameterized) regime, it helps to … NettetCosine Annealing is a type of learning rate schedule that has the effect of starting with a large learning rate that is relatively rapidly decreased to a minimum value before being increased rapidly again. The resetting of the learning rate acts like a simulated restart of the learning process and the re-use of good weights as the starting point of the restart …
