A new research paper explores hyperparameter transfer, a technique crucial for efficiently training large language models. The study introduces a framework with three metrics to quantify this transfer and investigates why certain parameterizations, like Maximal Update ($\mu$P), outperform standard methods. Researchers found that a key factor in $\mu$P's success is its higher embedding layer learning rate, which stabilizes training and improves hyperparameter transfer compared to standard parameterization.
