Nettet9. mar. 2024 · That is the correct way to manually change a learning rate and it’s fine to use it with Adam. As for the reason your loss increases when you change it. We can’t even guess without knowing how you’re changing the learning rate (increase or decrease), if that’s the training or validation loss/accuracy, and details about the problem you’re solving.
