Learning rate step gamma
Nettet25. jan. 2024 · the AdamW optimiser computes at each step the product of the learning rate gamma and the weight decay coefficient lambda. The product gamma*lambda =: p is then used as the actual weight for the weight decay step. To see this, consider the second line within the for-loop in the AdamW algorithm: Netteteta [default=0.3, alias: learning_rate] Step size shrinkage used in update to prevents overfitting. After each boosting step, we can directly get the weights of new features, …

However, if we use too large a learning rate, then the iterates get further and further away from the minima and we get divergence. In practice, we would want to use a learning rate that is just a little less than diverging.
