Norm Decay and the Nuclear Non-Proliferation NormDoyle, Thomas E
后面在stack上看到一个小哥说用batch norm要非常耐心的等待他warm up,这才想到moving average的计算方式是以一个参数renorm_decay来 计算滑动平均的,这个值的默认值是0.99,如果训练的轮次太少,moving_average还保持在一个和初始值很接近的值,远远没有收敛,导致预测时结果错误。
在随机优化理论中,学习率往往设置为常数或者逐渐衰减 (decay),从而保证算法收敛,这种学习率的设置方法也与机器学习里很多任务上的实际经验类似。然而,不管是设置学习率为常数还是使学习率逐渐衰减都不能让Transformer很好地收敛。 在优化Transformer结构时,除了设置初始学习率与它的衰减策略,往往还需要在训练的初始阶段设置...
10 is_training:图层是否处于训练模式。在训练模式下,它将积累转入的统计量moving_mean并 moving_variance使用给定的指数移动平均值 decay。当它不是在训练模式,那么它将使用的数值moving_mean和moving_variance。 11 scope:可选范围variable_scope 注意:训练时,需要更新moving_mean和moving_varia...
另外,在实现时一般使用一个decay系数来逐步更新moving_mean和moving_variance,moving_mean = moving_mean * decay + new_batch_mean * (1 - decay) 三、tensorflow中的三种实现 tensorflow中关于batch_norm现在有三种实现方式。 1、tf.nn.batch_normalization(最底层的实现)...

However, the decay rate is related to the initial state parameters and parameters of the bit flip channels. Contrary to the view at first glance, we find that the bit flip channels even have cohering power. 展开 关键词: Quantum coherence Open quantum system Decay rate ...
