Tīmeklis2015. gada 7. maijs · The "Dying ReLU" refers to neuron which outputs 0 for your data in training set. This happens because sum of weight * inputs in a neuron (also called activation) becomes <= 0 for all input patterns. This causes ReLU to output 0. As derivative of ReLU is 0 in this case, no weight updates are made and neuron is stuck … Tīmeklis2024. gada 14. marts · nan values as outputs just mean that the training is instable which can have about every possible cause including all kinds of bugs in the code. If you think your code is correct you can try addressing the instability by lowering the learning rate or use gradient clipping.

"TīmeklisReLU激活函数的提出就是为了解决梯度消失问题。 ReLU的梯度只可以取两个值：0或1，当输入小于0时，梯度为0；当输入大于0时，梯度为1。好处就是：ReLU的梯度的连乘不会收敛到0，连乘的结果也只可以取两个值：0或1 。如果值为1，梯度保持值不变进行前向传播；如果值为0 ,梯度从该位置停止前向传播。 Sigmoid函数是双侧饱和的， … " - Relu nan

Tīmeklis2015. gada 16. jūl. · When using unbounded activation functions (e.g. Relu) the softmax function can saturate. This can lead to nan gradients when paired with categorical crossentropy cost. If the softmax function is replaced with a numerically stable version of log-softmax and this is used directly in the cost function, then the gradients don't … TīmeklisTo analyze traffic and optimize your experience, we serve cookies on this site.
