In your … WebMar 20, 2024 · Worse, a high learning rate could lead you to an increasing loss until it reaches nan. Why is that? If your gradients are really high, then a high learning rate is going to take you to a spot that's so far away from the minimum you will probably be worse than before in terms of loss.

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. WebMar 29, 2024 · Contrary to my initial assumption, you should try reducing the learning rate. Loss should not be as high as Nan. Having said that, you are mapping non-onto functions as both the inputs and outputs are randomized. There is a high chance that you should not be able to learn anything even if you reduce the learning rate. orange and grey color scheme

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 1, 2024 · Because our learning rate was so high, combined with the magnitude of the gradient, we “jumped over” our local minimum. We calculate our gradient at point 2, and make our next move, again, jumping over our local minimum Our gradient at point 2 is even greater than the gradient at point 1!
