Print current learning rate of the Adam Optimizer?

WebbAdam is an optimizer method, the result depend of two things: optimizer (including parameters) and data (including batch size, amount of data and data dispersion). Then, I think your presented curve is ok. Concerning the learning rate, Tensorflow, Pytorch and … Webb20 mars 2024 · Adam has a separate learning rate for each parameter. The param_group ['lr'] is a kind of base learning rate that does not change. There is no variable in the PyTorch Adam implementation that stores the dynamic learning rates.

WebbWe fixed the initial learning rate to 0.001 which represents both the default learning rate for Adam and the one which showed reasonably good results in our experiments. Figure 2 shows the results for 12 settings of the weight decay of Adam and 7 settings of the normalized weight decay of AdamW. WebbSetting learning rates for plain SGD in neural nets is usually a process of starting with a sane value such as 0.01 and then doing cross-validation to find an optimal value. Typical values range over a few orders of magnitude from 0.0001 up to 1. Webb19 nov. 2024 · Thank you for this repo! I saw that you rewrite the "lr" to "learning_rate" but now new problems appears..
