WebSep 5, 2024 · One possible cause is a high learning rate. High values of this hyperparameter usually cause updates that are too drastic, and therefore divergence from the optimum. Please keep in mind this is only a suggestion, your problem might be due to completely different reasons. Try different learning rates and schedules, in order to understand if that ... WebAug 28, 2024 · Training neural networks can become unstable, leading to a numerical overflow or underflow referred to as exploding gradients. The training process can be made stable by changing the error gradients either by scaling the vector norm or clipping gradient values to a range.
WebJul 17, 2024 · It happened to my neural network, when I use a learning rate of <0.2 everything works fine, but when I try something above 0.4 I start getting "nan" errors because the output of my network keeps increasing. From what I understand, what happens is that if I choose a learning rate that is too large, I overshoot the local minimum. WebJul 21, 2024 · Learning rate refers to the amount by which the weights are updated during training (also known as step size) of machine learning models. It is one of the important hyperparameters used in the training of neural networks and the usual suspects are 0.1, 0.01, 0.001, 0.0001, 0.00001, 0.000001 and 0.000001.
WebJan 25, 2024 · This seems weird to me as I would expect that on the training set the performance should improve with time not deteriorate. I am using cross entropy loss and my learning rate is 0.0002. Update: It turned out that the learning rate was too high. With low a low enough learning rate I dont observe this behaviour. However I still find this peculiar.
WebJul 25, 2024 · Play around with your current learning rate by multiplying it by 0.1 or 10. 37. Overcoming NaNs. Getting a NaN (Non-a-Number) is a much bigger issue when training RNNs (from what I hear). Some approaches to fix it: Decrease the learning rate, especially if you are getting NaNs in the first 100 iterations.
