TīmeklisReLU has a range of [0, +Inf). So, when it comes an activation value z=0/1 produced by ReLU or softplus, the loss value computed by cross-entropy : loss = - (x*ln (z)+ (1 … Tīmeklis2024. gada 7. dec. · Averu December 7, 2024, 12:09pm #1. nn.ReLU randomly outputs Nan on forward.

Tīmeklis有了這個,訓練損失在大約 30 輪后突然跳到 NaN,批次大小為 32。如果批次大小為 128,在大約 200 輪后梯度仍然爆炸。 我發現,在這種情況下,由於邊緣屬性e ,漸變會爆炸。 如果我沒有將neighbors_mean與e連接起來,而只是使用下面的代碼,就不會出現 … Tīmeklis2024. gada 7. dec. · nn.ReLU randomly outputs Nan on forward. The problem only appears on GPU and not on CPU. I captured ReLU input and outputs. This happens randomly on different parts of my torchvision VGG_16bn backbone, but allways at the first half of layers. For example in one of the calculations where output contained a …
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 … Tīmeklis2024. gada 7. dec. · The neural network I trained is the critic network for deep reinforcement learning. The problem is when one of the layer's activation is set to be …
TīmeklisI'm also getting this problem (Ubuntu 14.04, GTX 980Ti/970, Theano as backend, CNN with residual units, ReLU, BN, mse/mae loss). In my case problem occurred randomly, the probability of getting nan is increasing with model's complexity (and memory usage).
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, … song old town road kidz bopTīmeklis2024. gada 2. maijs · the loss is nan · Issue #14 · hunglc007/tensorflow-yolov4-tflite · GitHub. hunglc007 / tensorflow-yolov4-tflite Public.
