论文AdamW里对比了Adam+L2 与AdamW(Adam+weight decay)两种优化器,然后采用不同的lr schedule方式进行实验。最后的实验结果表明,虽然Adam及AdamW是一种自适应lr的Adam优化器方法,应该来说不需要增加额外的lr scheduler方法,但在它的实验中,加了lr decay的Adam还是有效提升了模型的表现。 但这只是在它的实验里进行了...

Note: when applying a decay to the learning rate, be sure to manually apply the decay to the weight_decay as well. For example: decay = tf.train.piecewise_constant(tf.train.get_global_step(), [10000, 15000], [1e-1, 1e-2, 1e-3]) lr = 1*decay wd = 1e-4*decay # ... op...
Excuse me,what would be the difference of accuracy if I didn't add param{lr_mult, and decay_mult} when training? What is the default value(lr_mult, and decay_mult)for Caffe?
pytorch learning rate decay 本文主要是介绍在pytorch中如何使用learning rate decay. 先上代码: 代码语言:javascript 复制 defadjust_learning_rate(optimizer,decay_rate=.9):forparam_groupinoptimizer.param_groups:param_group['lr']=param_group['lr']*decay_rate ...
很多时候我们要对学习率(learning rate)进行衰减,下面的代码示范了如何每30个epoch按10%的速率衰减: def adjust_learning_rate(optimizer, epoch): """Sets the learning rate to the initial LR decayed by 10 every 30 epochs""" lr = args.lr * (0.1 ** (epoch // 30)) ...
Caffe入门:lr_mult和decay_mult参数说明,一、Caffe网络定义:lr_mult和decay_mult通常在Caffe的网络定义中,某些layer会有如下参数:param{lr_mult:xdecay_mult:y}当令lr_mult=x
Proposition 1 : There exists aL~(η)for any learning rateη. It is the lossLif we keep the learning rate fixed atηand train for infinite time. Remark : Instead of testing multiple runs, we can quickly estimateL~(η)by setting LR =ηand train an already-converged model. The lossLwill...
