New principle optimizes AI model training by aligning gradients and updates

Researchers have introduced a new principle called Greedy Alignment for selecting and tuning optimizer hyperparameters in machine learning. This principle treats optimizers as causal filters that map gradients to updates, aiming to minimize loss over a set of optimizers. The theory suggests a greedy approach to finding the optimal momentum for optimizers like SGD and Adam, which has been validated through experiments on image classification and language model fine-tuning tasks.
