Hight learning rate nan
WebJul 16, 2024 · Taken that classic way of cross-entropy would cause nan or 0 gradient if "predict_y" is all zero or nan, so when the training iteration is big enough, all weights could suddenly become 0. This is exactly the reason why we can witness a sudden and dramatic drop in training accuracy. WebDec 26, 2024 · First, print your model gradients because there are likely to be nan in the first place. And then check the loss, and then check the input of your loss…Just follow the clue and you will find the bug resulting in nan problem.

WebIf the loss does not decrease for several epochs, the learning rate might be too low. The optimization process might also be stuck in a local minimum. Loss being NAN might be … 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.

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!
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.
WebJun 28, 2024 · The former learning rate, or 1/3–1/4 of the maximum learning rates is a good minimum learning rate that you can decrease if you are using learning rate decay. If the test accuracy curve looks like the above diagram, a good learning rate to begin from would be 0.006, where the loss starts to become jagged. green and yellow checkered bikiniWebMay 28, 2024 · pytorch-widedeep, deep learning for tabular data IV: Deep Learning vs LightGBM A thorough comparison between DL algorithms and LightGBM for tabular data for classification and regression problems May 28, 2024 • Javier Rodriguez • 56 min read 1.
