WebNov 9, 2024 · The two constraints you have are: lr (step=0)=0.1 and lr (step=10)=0. So naturally, lr (step) = -0.1*step/10 + 0.1 = 0.1* (1 - step/10). This is known as the polynomial learning rate scheduler. Its general form is: def polynomial (base_lr, iter, max_iter, power): return base_lr * ( (1 - float (iter) / max_iter) ** power) WebPyTorch Lightning Module. Finally, we can embed the Transformer architecture into a PyTorch lightning module. From Tutorial 5, you know that PyTorch Lightning simplifies our training and test code, as well as structures the code nicely in separate functions. We will implement a template for a classifier based on the Transformer encoder.
